2.1 The Microbiological Laboratories Isolation of organisms for new products normally does not occur in laboratories associated with production cultures, however, production (microbiological) laboratories frequently do mutation and isolation work to produce strains with higher yields, to suppress a by-product, to reduce the formation of a surfactant, to change the physical properties of the broth to facilitate the product recovery
Specific nutritional requirements of microorganisms used in industrial fermentation processes are as complex and varied as the microorganisms in question. Not only are the types of microorganisms diverse (bacteria, molds and yeast, normally), but the species and strains become very specific as to their requirements
