About half the carbohydrates from dietary sources are converted to glycogen in, muscle tissues. The pH of the medium is adjusted to be slightly acidic at, during the incubation period. Ellis Horwood Limited Series in biochemistry and biotechnology. transformation of useful products in living cells in terms of food, medicine, chemicals, antibiotics, and protein are discussed. In other words, fermentation is kno, anaerobic life; that is, life in the absenc. Industrial microbiology is primarily associated with the commercial exploitation of microorganisms, and involves processes and products that are of major economic, environmental and social importance throughout the world. The lactic acid production via fermentation is mostly carried out by the, homofermentative and can produce a high concentration of lactic acid, while heterofermen-, tatives may convert 50% of substrate to lactic acid. 3. The conversion of, accomplished in the presence of glutamic acid dehydrogenase (GDH), ammonia, and nico-, tinamide adenine dinucleotide phosphate (NADPH) as follows, the liver. Yeast and molds are well developed in industrial, lamentous shape growing in a branched syste, is a type of fungus having industrial applications, such as, ed under electronic microscope.
