MICROBES AND FOOD – A ‘RELATIONSHIP’ Microbes and food have always had a love-hate relationship. Food producers have learned to harness their power -- and sometimes for good use. There is no doubt that organically grown fruits and vegetables are superior in flavor. Now‚ despite arguments to the contrary made by food manufacturers‚ they may well be more nutritious for a variety of reasons. There are always studies available to prove any point‚ especially one

1. Eukaryotic cells have a true nucleus‚ bound by a double membrane. Prokaryotic cells have no nucleus. The purpose of the nucleus is to sequester the DNA-related functions of the big eukaryotic cell into a smaller chamber‚ for the purpose of increased efficiency. This function is unnecessary for the prokaryotic cell‚ because its much smaller size means that all materials within the cell are relatively close together. Of course‚ prokaryotic cells do have DNA and DNA functions. Biologists describe

Biology 181 Ana Marti-Subirana Identification of unknown a-Amylase through testing different temperatures and pH values to detect the absorbance of maltose. Introduction: Enzymes are biological catalysts‚ mainly proteins for this experiment‚ generated by an organism to speed up chemical reactions. They have active sites on which the substrate is attached‚ and then broken up or joined. For this experiment we are going to work with the enzyme a-amylase. Amylase is an enzyme that breaks

Abstract: Stevia rebaudiana is an herb with a very high medicinal value. It has more than 100 phytochemicals. It is used as sugar substitute. The extracts from leaves are used for the microbial assay and study the antimicrobial activity. The microbes used for the testing the activities are E.coli‚ Staphylococcus aureus‚ Bacillus subtilis‚ Salmonella typhi‚ Aspergillusniger‚ Candida parapsilosis‚ Trichophyton rubrum. With different concentrations of the extracts starting from 2.5µg/ml‚ 5.0µg/ml‚ 7

Name of Student: Bal Krishna Maharjan Course: Food Microbiology 17/FA Describe how to isolate and differentiate between molds and yeasts? Answer: Isolation of molds: Isolation of molds can be done in two ways: 1. Direct isolation: Under this different methods can be selected depending upon the nature of molds and need of study. The following are the different direct isolation techniques. a. Direct transfer: Involves simple transfer of a mold from its source to a pure culture‚ usually consists of

belonging to the genus Aspergillus are most commonly used for the production of amylase. Traditionally‚ most of the production of amylase is carried out by submerged fermentation‚ a process which is a method for growing pure cultures of aerobic bacteria‚ and are incubated in a liquid medium subjected to continuous vigorous agitation. Because of the ease of handling and a greater control of the environmental factors like temperature and pH‚ microorganisms like Aspergillus can also be grown on moist
