Determining The Property Of An Enzyme

Bacterial cell counts of food for thought Many of the foods we consume nonchalant are contaminated with microorganisms. In many instances these organisms are inwrought to the production process of the food itself, and are considered harmless, or plain beneficial. Many foods such as beer, wine, cheese, pickles, sausages, and dairy products are produced as a result of microorganisms metabolizing starting products into the finished products we later enjoy. not all organisms are welcome, and certain groups empennage be considered stabbing and may signal that the food supply has been contaminated. Contamination can lead to food poisoning and rapid spoilage. In the food industry the payoffs of bacteria are regularly monitored to train the safety of our food supply. One of the groups of microorganisms that are of a point concern to the food industry is the coliform bacterium. Organisms of this group are negative bacilli that ferment lactose under anaerobic conditions. The presence of coliforms is a lot used as sign of fecal contamination as coliforms are abundant in the feces since they reside in the colon and small intestine of mammals. Although we live in constant contact with these organisms they have been known to cause a number of severe food-poisonings that can lead to death.



Most coliforms are kinda easy to culture in the laboratory, and this makes monitoring their presence exemplification in general it is thought that the presence of coliform organisms indicates that other pathogenic organisms of fecal origin may be present as well. We will be using a selective and differential coefficient strength to identify coliform contamination in our milk samples. reddish blue red bile agar is a medium ordinarily used for the enumeration of coliform organisms in food and dairy products. The selectivity of the medium is due to the presence of bile salts and crystal violet. These ingredients inhibit the step-up of Gram-positive organisms such as Lactobacillus, Streptococci, and Staphylococci.
