Introduction • Food supply consists basically of plants and animals or product derived from them. This includes eukaryotes (organisms with a nucleus), such as fungi and protists, and prokaryotes (organisms without a nucleus), such as bacteria. Putrefaction caused by C. sporogenes may cause a can to swell and burst, releasing its partially digested contents and a putrid odour. Absolutely no food, drinks, chewing gum, or smoking is allowed in the laboratory. Microbiology Lab Practices and Safety Rules 1. Fermentation ensures not only increased shelf life and microbiological safety of a food but also may also make some foods more digestible and in the case of cassava fermentation reduces toxicity of the substrate. Prevention—or, more accurately, minimization—of contamination is achieved by the sanitary handling of raw food products, inhibition of growth by low temperatures (refrigeration or freezing), dehydration by evaporation or by high concentrations of salt or sugar, and killing of microbes by the application of high temperatures and, in some instances, radiation. Industrial Microbiology also plays an important role in the preservation of the environment. Many go on to earn master's or doctorate degrees as well. Preservation of foods by fermentation is a widely practiced and ancient technology. Microbiologists are employed in both the public and private sectors across a broad spectrum of industries. Microbiology is the study of microorganisms, their impact on humans, their roles in human physiology, and their roles in the environment. The changes vary according to the type of food degraded but can be summarized by examining the fates of the major nutrients found in food: proteins, carbohydrates, and fats. The product formed by the metabolism of the microorganism must be removed from a heterogeneous mixture that also includes a tremendous crop of microbial cells and unused constituents of the medium, as well as products of metabolism other than those being sought. Foodborne illnesses are a … One example of what can be achieved via recombinant DNA technology is the production of human insulin by a genetically altered strain of E. coli. One example of microbial spoilage of canned foods is “sulfide spoilage” caused by C. nigrificans, in which contents are blackened and have the odour of rotten eggs. (2014). Microorganisms play an important role in food industry. Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox.
