V Neurotoxins Afect the nervous system, causing dizziness, blurred or double vision, the inability to swallow, skeletal muscle weakness, and/or laccid paralysis. In Dairy Industry, Lactobacillus bacteria are used in fermentation of lactose sugar to form lactic acid (in curd). Submitted To Department of Biotechnology. Presentation Summary : Bacteria has the following economic eficial effects.  These products are very suitable for For many years, detection and identification of microorganisms in foods, animal feces, and environmental samples have relied on cultural techniques regarded as the "gold standard". Keep raw food totally separated from cooked product. Microbes are very useful in creating some of the mass produced products that are consumed by people. Clipping is a handy way to collect important slides you want to go back to later. Food Microbiology: Microbiological analysis is important to determine the safety and quality of food. Fermentation not only gives food a good taste, texture and smell, but it causes changes that reduce the growth of unwanted food microbes. Beneficial Microorganisms in Food Beneficial microorganisms includes all the microbes can be processed in such a way that it can be utilized in a healthy product.

The use of raw food and ingredients from unsafe sources 2. In this process, manufacturers mix the flax plant with pectinase to decompose the pectin “cement” that holds cellulose fibers together. It thus becomes necessary to know the chemistry of milk, its spoilage, method of preservation, and different dairy products where microbes play a positive rather than negative role. It could also be used in more general study of food production. The cellulose fibers are then spun into linen. Medicinally, microbes can be used for creating antibiotics in order to treat antibiotics. As already discussed in the earlier article Contributions of Microbiology in Food Industry, they are used in production of various food products, and are also responsible for food spoilage thereby causing intoxication and diseases.
