Whole Foods Market Input Analysis

The Firm’s Strategy One of the significant tricks being sought after by the firm is the separation. The firm embraces the separation technique as far as item arrangement so as to upgrade its upper hand. Actually, the firm has guaranteed that all its business forms including items are novel to the industry.Advertising We will compose a custom appraisal test on Whole Foods Market Input Analysis explicitly for you for just $16.05 $11/page Learn More The significant driver for the technique is the expanded fitness of the business partners and representatives as far as abilities and capacities (Whole Foods Market, 2013). Additionally, the serious edge relies upon the degree where the firm’s business forms are led. At the end of the day, the firm cautiously chooses various brands of things that are profoundly esteemed by the clients. In any case, profoundly esteemed items draw in significant expenses. Entire Foods comprehends the affectability of costs. All things considered, the firm offers its top notch food items at reasonable costs that customers can manage. The blend of value and reasonable costs is one of the best upper hands to the firm (Whole Foods Market, 2013). As showed, Whole Foods is not the same as the significant rivals as far as the readied food brands. The firm offers a wide assortment of arranged suppers for lunch, supper and desert (Martin, 2008). Customers have the alternatives of eating on the premises or take out. Entire Foods exploits the expanding number of customers that typically have their dinners on the premises as top of the line buyers will in general search for methods of controling spending in the midst of a troublesome monetary circumstance (Martin, 2008). Also, the retail location lean towards the extraordinary brands for the regular significant treats found in a large portion of the stores. Since the firm has a thin specialty of clients and few contending stores are found in many regions it works, Whole Foods can witho ut much of a stretch output and comprehend the market. The systems are the fundamental givers of the firm’s higher net revenues (Martin, 2008). How the Strategy is Aligned to Porter’s Generic Model According to Porter’s nonexclusive powers model, methodologies are activities that help in the arrangement of resistant spot in the business (Porter, 1998).

Then again, hostile systems changes the basic reasons for the serious powers and as such changes nature in which the firm works. Doorman proposed thre e expansive and standard methodologies that the firm can use to produce solid faultless circumstances just as increment its upper hand. The procedures incorporate cost authority, separation and the concentration or the specialty methodology (Porter, 1998). The firm’s approach fits straightforwardly with the separation system of the Porter’s model. As per the model, the separation methodology implies offering administrations, items and brands that are interesting to the business (Porter, 1998). Basically, the separation methodology necessitates that the firm makes own market specialty. Ways to deal with the separation procedure incorporate assorted item plans, brand picture, assortment of highlights and the new innovation (Porter, 1998). Every one of these methodologies have been applied by Whole Foods to make its item marks along with serious costs to make its own market specialty. The separation system has contributed incredibly to the development of the firm in a pro foundly serious industry. Truth be told, the separation approach has protected the firm from the serious contention through the making of brand devotion and decrease of value versatility of interest by making customers to be less touchy to the value changes of the item (Martin, 2008). Additionally, the uniqueness of the items have made hindrances and the decrease of substitutes, which as a result, has prompted higher edges and diminishes the requirement for minimal effort advantage (Martin, 2008). In addition, higher edges empower the firm to deal with powerful providers. Truth be told, the technique has empowered the firm to ease the buyer’s power since barely any choices are accessible to the buyers (Whole Foods Market, 2013). The Firm’s Inputs According to the consistent model, authoritative sources of info are extending from the earth to the procedures applied by the firm (Nadler Tushman, 1980). Inside the continuum are sources of info, for example, assets and the firm’s history.Advertising We will compose a custom evaluation test on Whole Foods Market Input Analysis explicitly for you for just $16.05 $11/page Learn More The assets accessible to the firm incorporate human capital, mechanical applications, budgetary capital, data just as other impalpable resources.

As indicated by the model, natural data sources are factors that are outside the organizations impact including things that originate from an establishment or industry, people, bunches just as occasions (Nadler Tushman, 1980). Basically, the ecological information sources must impact the association. For this situation, the firm’s ecological sources of info incorporate industry innovative work, providers and in particular natu ral food customers. Additionally, assets incorporate all advantages that the firm can get to. The assets incorporate both human and money related capital just as data. What's more, assets incorporate impalpable resources, for example, acknowledgment by the market specialty. For the most part, the asset inputs are expansive and ordinarily applied by the firm to create the ideal result (Nadler Tushman, 1980). Regarding the info history, past choices, exercises and conduct are considered as more noteworthy exertion to achieve the current wanted outcomes. Basically, these elements must impact the current hierarchical activities. Entire Foods is known for its customary quality natural food contributions, which the firm endeavor to build its upper hand. Regardless of whether the Inputs are Congruent to the Strategy According to the harmonious model, the firm’s system is the flood of choices concerning the way where the information sources or the hierarchical assets are changed to a ddress the issues of the customers. Also, techniques are including the way the firm’s assets are arranged to manage restrictions just as possibilities accessible to the firm inside the setting of the examples of the past conduct (Nadler Tushman, 1980).

For this situation, the asset inputs fit incredibly to the firm’s system. Entire Foods has utilized every one of its assets so as to guarantee expanded upper hand. At the end of the day, the sources of info are adjusted to the firm’s system to achieve the ideal upper hand. Basically, the firm’s assets are exceptionally used to build the exhibition of the methodology. Truth be told, the firm has guaranteed that every one of its assets are adjusted to the vital objective of guaranteeing expanded upper hand. At the end of the day, the firm’s assets incredibly fit with the organization’s technique. Moreover, the firm has completely used its HR to accomplish the ideal it em marks. Likewise, the capital assets including money related and different resources have been completely used to guarantee that the particular and one of a kind food items are created to meet the customer needs. The objective clients’ worthiness of the items affirms the congruity of the assets to the system. The natural information sources accessible to the firm including customers have a more noteworthy level of congruity to the methodology of separation. The separation methodology targets expanding the objective client esteem. Inside the setting of Whole Foods Market, customers and providers are considered as individual information sources. The commitment of the providers and shoppers stays basic in the item improvement and conveyance. Be that as it may, as far as providers, the separation system has guaranteed a radical decrease of supplier’s power, which thusly has brought about expanding the firm’s execution. Basically, the firm’s natural assets a re profoundly harmonious to its system. Be that as it may, the history inputs genuinely fit with the present separation technique. The firm scarcely uses its authentic assets in the assurance of the present item contributions. All things considered, a portion of the viable choices that were made before structure the premise of the present methodology. References Martin, A. (2008, August 2).

The Minimum Legal Drinking Age Essay - 1599 Words

Appropriate Minimum Legal Drinking Age What is the right age to drink alcohol? Alcohol’s reputation varies from one culture to another. For some cultures, like the United States, they perceive it as a â€Å"forbidden fruit† while many European countries view it more leniently as another essential complement to their daily diet. In reality, alcohol is essentially a drug, that manipulates people’s minds to make them anxious, dizzy and aggravated. The law understands that drinking alcohol has some side effects and therefore trusts its citizens to be mature about it. According to some people the pros outweigh the cons of alcohol; this is precisely the reason why modern countries attempt to alleviate its circulation because of its effects or even setting restrictive laws upon it. However, with the creation of these laws also arose imminent opposition and doubt over the age of which the laws would restrict. While today’s minimum legal drinking age (MLDA) i n the United States is 21, some people argue that the ideal minimum drinking age is 18, because it is safer for the health and it demotes crime while those people face a large opposition stating that the drinking age shall not be 18. On the other hand there is the other side which states that alcohol should be restricted to the age of 25 or above.

New and Old World Archaeology Essay - 1520 Words

NEW AND OLD WORLD ARCHAEOLOGY Artifacts of the old and new world have some likeness but also have many differences. I made a visit to the Cobb Museum at Mississippi State University to analyze this for myself. When down there, I saw pottery, writing, tools, jewelry, and many other things from each world. I then found ten artifacts of each period that was listed in the back of my workbook on the spreadsheets and wrote descriptions of them. For the new Old World, I described the Moabite stone, Sarcophagus of Eshmunazar, the Roman bronze figure of Artemis, the 60 piece strand of beads, the 107 piece beaded necklace, the bronze beaker Iranian, the bronze Persian repousse bowl, the 11 bracelets, 5 human figurines, and the Rosetta Stone.

Its shaped kind of like cylinder. The bronze Persian repousse bowl is a deep bowl with a flower engraved interior in a dark bronze and green color that originated in 5th century B.C. The eleven bracelets that I saw were all green except one that was a thick, black, and bronze one. Most weren’t fully connected in a complete circle and some seem to be flexible for any sized wrist and others were solid. They all were very small in size. Of the five human figurines, three looked like soldiers in uniform with swords, shields, and head gear on for battle. The other two had cone shaped heads, skinny, hands directly on sides, while standing with a little bend to the knees. The Rosetta Stone originated in 196 B.C and was found in 1799 by Napoleon’s soldiers. It was important because it was a major key to translating Egyptian hieroglyphs. It was also in demotic script and ancient Greek (Cobb)†.

The Effects of Power and Fear on a Government Free Essays

The Effects of Power and Fear on a Government Fear is one of the few emotions everybody feels at some point in their lives. From their environment to the leaders that were in charge there were many things for the boys to be fearful of. Lord of the Flies, by William Gilding is about a group of boys stranded on an Island during World War II. We will write a custom essay sample on The Effects of Power and Fear on a Government or any similar topic only for you Order Now They have to deal with power struggles and situations they would have never thought of. In Lord of the Flies, the destructive power struggle between the primary characters mirrors the power struggle between Hitler and the Jews during World War II, and the current dictator Basher al- Sad and his citizens in Syria. Lord of the Flies represents a political allegory because some of the characters represent an abstract idea of government. Many people who have great leadership attributes but have a hard time with their appearance struggle, † Piggy is Ralph advisor, someone who is unable to rule because of his own social and physical shortcomings† (Winnfield). Nowadays appearance has become a huge part of the society at hand. Appearance helps a society decide what it wants to be like as well as ho to follow. Struggling with appearance Is not the only Issue, It Is also struggling with standing up for yourself. Which In the book It Is shown that Piggy struggles with this. † â€Å"Then went on piggy, that boy- I forgot â€Å"your talking too much† said Jack Merrier. â€Å"Shut up, Fatty. † Laughter arose and Piggy was silent† (Gilding 21). In a society there are many people just like Piggy. There are so many great leadership characteristics in people. The problem is if that Pearson can not stand up for themselves or any of their beliefs none of the great characteristics matter. This shows owe Lord of the Flies represents a political allegory because It shows how some of the characters Like Piggy represent an abstract Idea of government In the book. In addition to the characters representing government they also act similarly to past and current political figures in the world. Most people at some point In time have a chance at power, if they choose to take it they will most likely lose It eventually as well â€Å"Even Jacks power Is Illusory or at least temporary, vanishing the moment an adult authority arrives on the island† (Olsen). In this it is seen that the power Jack had elates to many figures in the world. The power Jack had though is instantly taken away when someone else with higher authority arrives. This happens all the time in the real world as well. In the book it adds on to the same situation even more so † Whoso boss here asked the officer? I am said Ralph loudly. A little boy with the pair of spectacles started forward then changed his mind and stood still† (Gilding 148). It is clearly shown that Jack loses the power he had quite quickly. This has happened to those in the real world, who thought they would never be run out of rower, such as Doll Hitler. As seen the characters in Lord of the Flies act similarly to past and current political figures in our world. In Lord of the Flies there is a very similar situation when Jack is put in control of the island and the rest of the boys, Just like when Doll Hitler was put in charge of Germany and it’s people. At some point in everybody’s lives they will most likely want to be in charge of something or be a leader of some sort, † Seen in this light, Hitler thought the only way to prevent Germany from losing again was to eliminate the impure groups from society. He also knew the only way he could accomplish this is if he rose to power† (â€Å"Doll† 1). In Lord of the Flies Jack thinks a lot like Hitler. When most people hear the name â€Å"Hitler† the first thing that comes to most minds is a dictator in Germany who killed Jews. This is true, but the reason behind that was Just because he wanted power. Hitless strong desire for power is a lot like Jacks. They both Just wanted to rule something which in their case it was people. Arrogance is a big reason for people wanting power † I ought to be chief said Jack with simple arrogance, because IM chapter chorister and head boy. I can also sing C Sharp said lace (Gilding 228). Jack obviously thought he was better than everybody else and was very arrogant. It was one thing that some of the boys didn’t like about him. Hitler was the same way, he normally thought no one was better than him and if he did he got rid of them quite quickly. Arrogance only got Jack and Hitler so far. Clearly shown the similar situation of Jack and Hitler being put in control shows the similarities of their leadership. Doll Hitler was a dictator during World War II, the character Jack acts much like Hitler in the book by emphasizing the strong desire of power and intolerance towards others. In life some people think the only way to fix certain problems is to completely get rid of them â€Å"Hitler implemented government policies based on anti-Semitism and racism. These policies became more severe over time and led to the extermination of the Jews, racial minorities and other groups† (â€Å"Doll†l). In Lord of the Flies it is seen that Jack does this quite often. He doesn’t really give any thought to what he is doing unless he really wants it done. For instance when Jack took Piggy as a really different errors and not in a good way. Eventually Jack got his way and Piggy died. Hitler does this with the Jews. He wanted the people who he thought were perfect and those people were not the Jews. So because he thought the Jews were the problem he started to kill them off. In the book we not only see Jack treating Apply harshly but he also treats some of the other boys the same way â€Å"I’m chief yelled Jack. Viciously, with full intention, he hurled his spear at Ralph. The point tore the skin and flesh over that Jack is willing to hurt people in order to get what he wants. This is such a moment where Jack showed the power he thought he had to the boys. It also gave the boys a reason to fear him. Jack was using this fear to control the boys much like Hitler. Fear can cause people to do unbelievable things including follow and listen to unwise rulers or leaders. This adds to the desperate wanting of power and intolerance towards others. Another Situation very similar to the one the boys are put into due to Jack is more current, the power struggle between Basher al-Sad and the harsh way he treats his citizens in Syria. Most dictators are harsh, cruel and will try and do anything to keep heir place secure muff need to show that you are strong, that you are a leader. You need to crush in the first moment any signs of opposition, resentment, or independence. As well as causing the people to fear you said Sad† (â€Å"Basher† 2). Basher al-Sad uses the harsh way he treats his citizens to produce fear so that no one will overtake his place as being leader in Syria. In the book when some of the boys start to show opposition Jack did exactly what Sad mentioned, he crushed it the moment it started. Which caused fear amongst the boys. Dictators find terrible hinges to do for no reason but to cause fear amongst their people † † Hess going to beat Wilfred! † â€Å"What for? â€Å"said Ralph but Robert shook his head doubtfully. â€Å"l don know he never said why’ The chief was sitting in the cave, naked to the waist, his face blocked out in white and red. The newly beaten and untied Wilfred was sniffing noisily in the background† (Gilding 160). In this it is clear that Jack Just beat Wilfred because he had been angry. This act caused fear amongst the group of boys. The fear caused kept the boys loyal to their chief. Jack would have had no way to control al the boys if he never used fear. This doesn’t mean its right by any means. Basher al-Sad and Jack both use fear in a harsh way to control their people and ideas of government. Basher al-Sad current dictator in Syria is very similar to the character Jack in Lord of the Flies such as some of their motives. In Syria there are many rules â€Å"Freedom of speech was only marginally restored but for the most part Sad kept it the same† (â€Å"Basher† 2). In Lord of the Flies Jack and Basher kind of relate to each other because the both did not allow freedom. The fact that Basher and Jack wouldn’t allow freedom of speech was most likely because they wanted to prevent any uproars or anything that could harm their spot in leadership. † â€Å"Then went on piggy, that boy- I forgot -† â€Å"your talking too much† said Jack Merrier. â€Å"Shut up, Fatty. † Laughter arose and Piggy was silent† (Gilding 21). Here we not only see Jack being cruel towards Piggy but we also see him limiting Piggy speech. This action is harsh and even though Piggy had freedom of speech it was almost as if Jack stole that from him. Most likely Piggy is not the only person Jack treated like that. This is how we can see some f Basher al-Sad and Jacks motives line up. In Lord of the Flies we see that fear plays a enormous role in the book. It plays off between the see between Jack and Ralph. Fear is a strong emotion and can cause many situations. We see this not only in the book Lord of the Flies but also in our everyday lives and other political power struggles in our World. Such as the fight for power in World War II with Doll Hitler and the Jews. It is even seen currently in Syria with Basher al- Sad and his citizens. Jack, Hitler, and Sad all have one main thing in common they all ruled with fear. How to cite The Effects of Power and Fear on a Government, Papers

Paper of Aflatoxin with Nanis free essay sample

The active antifungal substance(s) were separated, semi purified and characterized as a protein substance. The semi purified substance inhibited spores formation, thinned the conidiophores and deformed both strigmata and conidial heads. Key words: Aspergillus niger, Streptomyces noursei, ochratoxin A. INTRODUCTION Growing mould may produce toxic secondary metabolites, such as mycotoxins. Among hundreds of fungal secondary metabolites are mycotoxins which include aflatoxins (AFL), deoxynivalenol, fumonisins (FB), ochratoxin A (OTA), and zearalenone. They are of major health concern for humans and domestic animals (Miller, 1994). Mycotoxins can enter into the human food chain directly through foods of plant origin and indirectly through foods of animal origin (Kovacs, 2004). Many types of food products in the markets have been reported to be contaminated with AFL or metabolites of AFL. These include tree nuts, peanuts, figs, melon seed, pumpkin seed, sesame seed, sunflower seed, lotus seed, coix seed, red pepper, white pepper, nutmeg, paprika, mixed spices, rice, corn, mixed cereals, chilies, and copra (Wilson, 2002). We will write a custom essay sample on Paper of Aflatoxin with Nanis or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page OTA has been found in many cereals, raisins, cocoa products, green coffee beans, wine, soybeans, grape juice, pork sausages (Pittet, 2001), spices, and herbs (Patel et al. , 1996). Ueno et al. (1991) were the first to report on ochratoxin A production by a black Aspergillus species, Aspergillus foetidus. This was later confirmed by Teren et al. (1996) and Magnoli et al. (2003). Abarca et al. (1997) reported that two strains of Aspergillus niger produced OTA, and confirmed in numerous studies (Abarca et al. , 2003; Suarez-Quiroz et al. 2004). Horie (1995) reported OTA in Aspergillus carbonarius, and confirmed by Heenan et al. (1998), Varga et al. (2000), Abarca et al. (2003) and Sage et al. (2004). Biological control means the use of living agents to control pests or plant pathogens and offers an important alternative to synthetic chemicals. The use of bacteria like Pseudomonas sp. and Bacillus sp. , have been investigated due to their properties to produce antifungal metabolites and protect plants from fungal infection (Siddiqui et al. , 2005; Nourozian et al. , 2006). Biological control is being increasingly considered by the scientific community as a reliable alternative to pesticide utilization in field and in post-harvest. This biological approach is highly desirable for controlling fungal growth on grapes, helping to reduce the amount of *Corresponding author.

Actinomycetes are antibiotic producers that are capable of generating 75% of all known antibiotic products. Actinomycetes are a group of filamentous, Gram-positive bacteria (Williams et al. 1993). These organisms are aerobic, saprophytic, and mesophilic forms whose natural habitat is the soil. Several members of the Actinomycetes are known to be producers of important secondary metabolites, including antibiotics, herbicides, and growthpromoting substances (Connell, 2001). Over 55% of antibiotics have been isolated from the genus Streptomyces (Embley, 1994), and more than 400 species of the genus Streptomyces are mostly soil saprophytes. The gram-positive bacterium S. noursei ATCC 11455 produces a complex mixture of polyene macrolides generally termed nystatins (antifungal agent). The main objective of this study is to prevent or inhibit the growth of ochratoxin producing A. niger using biological method. In this connection, the potential effect of Actinomycete antagonistic to the test organism was focused. MATERIALS AND METHODS Source of used bacteria True and lactic acid bacteria (LAB) used in this study were obtained from Microbiology unit, Bacteriology Laboratory, Faculty of Science, Tanta University. The used Actinomycetes were isolated from soil samples collected from different localities in Egypt, namely Tanta, El-Mansoura, Kafr El-Zayat and El-Mehala El-Kobra. Soil samples were taken after the removal of about 5 cm of the surface, and then kept in clean plastic bags. Over the surface of solidified starch nitrate agar plates, 0. 2 ml samples of the soil dilution were spread out with a sterilized glass rod. The plates were then incubated at 28  ± 2 °C for 7 days. Biological control Different bacterial and Actinomycete isolates were grown in their corresponding suitable liquid media (Nutrient Broth for true bacteria, de Man, Rogosa and Sharpe (MRS) for LAB and starch nitrate for Actinomycetes) for 24 h and 7 days, respectively. Aliquots (100 ? l) of each cell free extract which was previously extracted by milling the cells in sterile saline were applied on the holes, and agar diffusion method was applied. After incubation for 5 days, the diameters of inhibition zones were measured. Characterizations of Actinomycete isolate number 3 For complete identification of the most fungal and ochratoxin antagonistic isolate, several physical, morphological and biochemical properties were examined. The criteria described in keys of identification (Kuster, 1972; Nonomura, 1974; Szabo et al. , 1975; Szabo and Csortos, 1975) were followed. Bergeys Manual of Systematic Bacteriology (Williams et al. , 1989) and Bergeys Manual of Systematic Bacteriology (Holt et al. , 1994) were followed for identification. These fall into the following classes: Microscopic characterization Light and scanning electron microscopes in Electron Microscope Unit, Tanta University (model JEOL, JSM-5200 LV) were used for the characterization of Actinomycetes. Determination of diaminopimelic acid (DAP)-isomer Diaminopimelic acid isomer was determined according to the method of Becker (1964) after modifications as follows: The Actinomycete isolate 3 was grown under shake culture conditions at 28 °C in nutrient yeast extract broth and the cells were collected after the achievement of a maximal growth 1 mg of the dried bacterial cells were hydrolyzed with 1 ml 6 N HCl in a sealed Pyrex tube held at 100 °C for 18 h. After cooling, the sample was filtered through Whatman no. 1 filter paper, which was then washed with 1 ml water. The filtrate was dried two or three consecutive times on a rotary evaporator under reduced pressure at 40 °C to remove most of the HCl. The residue was taken up in 0. 3 ml water and a volume of 5 ? l was then spotted on a thin layer macrocrystalline cellulose plate (Art 5577 Dc- Plastikfolien cellulose 20 ? 20 cm, layer thickness 0. 1 mm. Merck). For separation of amino acids, the following solvent mixture was used: Methanol-water- 10 N HCl – Pyridine (80: 17. 5: 2. 5: 10, by volume). Amino acids were detected by spraying with acetonic ninhydrin (0. 1, w/v), followed by heating for 2 min at 100 °C. Diaminopimelic acid (DAP) spots were olive- green fading to yellow, whereas the other amine acids exhibited purple spots. Physical and nutritional factors influencing the growth and antifungal activity of Streptomyces sp. To find out the best growth and antifungal activity of the best antagonistic organism, we study the effect of different media, pH, temperature, carbon and nitrogen sources. Partial purification of antifungal substance(s) produced by experimental Actinomycete isolate Fractionation by salting out with ammonium sulfate A modified technique of Jakoby (1971) was used. Different concentrations of ammonium sulfate (25, 50, 75 and 90%, (w/v)) were investigated. The supernatant – ammonium sulfate mixture was kept for 30 min at 4 °C before being separated by centrifugation. The precipitate was dialyzed in a dialysis bag in buffer in a refrigerator at 4 °C over night until the protein precipitate inside the bag became free from excess sulfate. Protein analysis Native electrophoresis The methods described by Stegemann et al. (1985) were applied as follow: Gel electrophoresis: Dissociating polyacrylamide gel electrophoresis (SDS-PAGE) was carried out according to a protocol proposed by Laemmli (1970). Subunit molecular weight estimation by SDS-PAGE: The method of Weber and Osborne (1969) was used to determine the apparent (subunit) molecular weight of proteins dissolved or extracted in the presence of sodium dodecyl sulfate (SDS). Mode of action of antifungal substance: Different concentrations (0. 10, 0. 25 and 0. 50%) of the active protein extracted from 668 Afr. J. Biotechnol. Table 1.

Among different bacteria, isolate 3 of Actinomycete (Photo 1) was the best bacterial isolate that revealed the highest antifungal activity against A. niger. Factors influencing growth and antifungal activity of isolate 3 Figures 1, 2, 3, 4 and 5 illustrate the effect of different conditions on growth of isolate no 3. The optimum growth was on starch nitrate medium containing starch as carbon source and potassium nitrate as nitrogen source, at 30 °C, pH 7. Characterization and identification of Actinomycete isolate no 3 Out of the 7 isolates of Actinomycetes, organism no 3 was the most active organism that inhibited the growth of ochratoxin A producing A. niger. It was subjected to further studies in order to be characterized and identified. Light microscopic examination showed the shape of the branches arranged in whorls and spiral spore chain (Photo 2). Scanning electron microscope (Photo 3) showed the spiny spore surface. The data obtained from the previous characterization program (Table 2) suggesting that isolate no 3 belong to genus Streptomyces as indicated by the colour of its aerial mycelia and the presence of LL-DAP in the cell wall, spore form, physiological and biochemical characteristics. On the basis of the pervious characters, this isolate showed to be similar to S. noursei. Thus, it could be concluded that the Actinomycete isolate no 3 is suggestive of being related to S. noursei and thus could be given the name S. noursei. Extraction and semi-purification of the antifungal substance Here, a study on the purification of antifungal substance extracted from the culture broth of the tested S. noursei was carried out. Fractionation by salting out with ammonium sulphate Ammonium sulphate was the best precipitant agent used to separate the antifungal substance from S. noursei and showed the highest antifungal activity.

Statistical analysis One-way analysis of variance (ANOVA) was carried out. Separation between different means was carried out according to Duncan multiple range test (LSR) and the simple linear correlation analysis (r) were carried out according to SAS (1985) software for windows version (6. 2). All experiments and analytical determinations were replicated at least three times. RESULTS Control by antagonistic microorganisms Effect of different bacteria on ochratoxin producing A. niger the growth of In this experiment, different types of bacteria were tested to control the growth of the common fungal producer of ochratoxin (A. niger) which was p reviously isolated and identified from herbs and medicinal plants in Egypt.

Gel electrophoresis of protein polyacrylamide gel and SDS-PAGE The obtained antifungal substance was by native performed to native polyacrylamide gel and SDS-PAGE to illustrate the subunits structure to confirm the degree of purity. In the case of native polyacrylamide gel, it was presented as one thick band (Photo 4). The final eluted proteins were subjected to SDS-PAGE according to the method of Laemmli (1970).

Allam et al. (2008) detected the fungal contamination of 22 investigated samples of herbal and medicinal plants in Egypt. A total of 7 species of fungi belonged to 5 genera were isolated and identified as Aspergillus, Penicillium, Fusarium, Botrytis and Cladosporium. The greater number of species was related to the genus Aspergillus, including A. iger, A. flavus and A. terreus and the formers were the most dominant and the responsible one for ochratoxin A production was A. niger. In the present study, biological control of ochratoxin A producing A. niger using antagonist bacteria and Actinomycetes was applied through screening program using liquid cultures. The program showed that Actinomycete isolate no 3 was the most potent organism whi ch gave the best antifungal activity. Subsequently, it was subjected to further studies in order to be characterized and identified. It was found that the selected isolate can grow well on starch nitrate medium, it is aerobic, spore forming, Gram positive, isolated from soil, spore mass was gray. The aerial mycelium with long straight filaments bearing at more or less regular spindles, the vegetative mycelium produced branched mycelium with the presence of LL-DAP in cell wall. All of the previous characters confirmed that the selected isolate belong to the genus Streptomyces. Microscopic examination showed spiny spore surface and spiral spore chain. The growth on carbon and nitrogen source in synthetic media and other characters are useful in species determination. Following the international keys of Kuster (1972), Nonomura (1974), Szabo et al. (1975) and Szabo and Csotros (1975), the survey of literatures on the description of Streptomyces species was done with these keys. In addition, Williams et al. (1989) and Holt et al. (1994) indicated that this isolate belongs to S. noursei and thus the name S. noursei is given. The polyene macrolide antibiotic nystatin produced by S. oursei is an important antifungal agent. The nystatin molecule contains a polyketide moiety represented by a 38-membered macrolactone ring to which the deoxysugar Allam et al. 673 Photo 3. Photography of scanning electron microscope showing the spore surface of isolate (3) at magnifications; (a) x7500 (b) x20000. mycosamine is attached. Molecular cloning and characterization of the genes governing the nystatin biosynthesis is of considerable interest because this information can be used for the generation of new antifungal antibiotics (Brautaset et al. 2000). The present results showed the promotion or inhibition of biological control organism to inhibit the fungal growth as well as the presence of ochratoxin on the contaminated herbs may be related to the different chemical contents which are present in each type of herbs. This hypothesis led to an examination of the effect of different factors which may be present in the surround environ- ment of medicinal and food herbs on the growth of S. noursei and its antifungal acti vity. Fractional precipitation of crude antifungal substance produced by S. oursei was performed by using different concentrations of ammonium sulphate. Results obtained showed that the ammonium sulphate at concentration 50% was the most suitable to give the highest antifungal activity. The use of ammonium sulphate for protein extraction was reported by Chitte and Dey (2000) on Streptomyces megasporus, Patcharaporn et al. (2008) on Shizophyllum commune BL23, Cheng et al. (2006) on B. subtilis DC33 and Wang et al. (2007) on B. subtilis LD-8547. 674 Afr. J. Biotechnol. Table 2. Characterization and identification of isolate.
