The following points highlight the top six microbial sources of enzymes. The sources are: 1. Production of Enzymes by Microbial Fermentation 2. Strain Improvement 3. Fermentation 4. Isolation and Purification 5. α-Amylase 6. Amyloglucosidase. Microbial Source # 1. Production of Enzymes by Microbial Fermentation: Enzymes are proteins, which catalyse specific biochemical reactions in a very efficient manner. Enzymes have been [...]
In this article we will discuss about the commercial production and use of yeast. Commercial Production of Yeast: Pure cultures of the selected strains of Saccharomyces cerevisiae are maintained in test tubes in laboratory. The test-tube cultures are increased to suitable volumes for commercial production (Fig. 40.9) by transferring them to the tanks containing bulk medium. Great care has to [...]
