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

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

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

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

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

Erik Fountain Kinkajou Bestiary The Discreet Kinkajou Not rare‚ but hard to come by‚ the kinkajou (Potos flavus) is a small‚ honey-colored‚ nocturnal rainforest mammal related primarily to the raccoon. On average‚ the kinkajou weighs four to seven pounds but can range anywhere from three to ten. To compensate for its small body‚ the kinkajou has a tail around twenty inches long. This animal uses its tail as a fifth arm‚ usually to hang from branches or help with balance. The kinkajou lives
