Pharmaceutical microbiology: the study of microorganisms that are related to the production of antibiotics, enzymes, vitamins, vaccines, and other pharmaceutical products and that cause pharmaceutical contamination and spoil.
Industrial microbiology: the exploitation of microbes for use in industrial processes. Examples include industrial fermentation and wastewater treatment. Closely linked to the biotechnology industry. This field also includes brewing, an important application of microbiology.
Food microbiology: the study of microorganisms causing food spoilage and foodborne illness. Using microorganisms to produce foods, for example by fermentation.
Although the exact ways of actions are not fully understood, the possible modes of probiotics action include the following: enhancement of epithelial barrier function; increased adhesion to intestinal epithelial cells; competitive exclusion of pathogenic microorganisms, and; production of antimicrobial peptides.
Lipases are a group of water-soluble enzymes that catalyze the hydrolysis (and synthesis) of ester bonds in insoluble acylglycerols at lipid-water interfaces. Lipases hydrolyze triacylglycerides into diacylglycerides, monoacylglycerides, free fatty acids and glycerols. Lipase reaction occurs at the interface between the aqueous and the oil phases because of an opposite polarity between the enzyme (hydrophilic) and their substrates (lipophilic).
Idli is a white, fermented acid (leavened), soft, spongy textured product and steamed cake of rice and dehulled black gram dhal eaten in Southeast Asian countries. is a very popular fermented breakfast food consumed in the Indian subcontinent made mainly of rice and black gram. Soybean, green gram and chick pea can be substituted for the black gram.
The use of microbes in wastewater treatment plant is an integral piece of the treatment process, as microorganisms are used in the secondary treatment of wastewater to remove dissolved organic matters. In this seminar abstract, the presenter showed an overview of the usefulness of fungal treatment of wastewater.
Garri is perhaps the second-ranking most staple food in Nigeria, ranking closely after rice.However, despite its popularity, the product is highly deficient in almost all food classes except carbohydrate. This has prompted numerous attempts by food scientists to fortify it with other classes of food, especially foods rich in protein.
