Often inducers are analogs or derivatives of the substrate, e.g., isopropyl--D-thiogalactoside for -galac- tosidase. The enzymes are classified into six major. Fermentation processes for microbial production of enzymes can be carried out through solid state culture or using submerged culture of microorganisms. Amylases hydrolyse gelatinised starch, which tends to stick on textile fibres and bind other stain components. The selection of a suitable strain for the required purpose depends upon a number of factors, in particular upon the nature of the substrate and environmental conditions. A large number of microorganisms, including bacteria, yeast and fungi produce different groups of enzymes.Selection of a particular strain, however, remains a tedious task, especially when commercially competent enzyme yields are to be achieved. enzymes, organic acids, biopolymers, and biosurfactants, and the processes for isolating and purifying them from a production medium. The available models for predicting the causal effects of changes of control variables are not simple and not accurate. (7) The strain must not produce toxic substances and should be free of antibiotic activities. The general aspects of this procedure can be outlined as follows: (1) Extracellular enzymes are preferred, because difficult and costly methods of cell disruption are not necessary. Kalashnikov et al. Strain Improvement 3. However, comparatively little is known about the mechanism(s) by which readily utilizable C sources repress the synthesis of many enzymes involved in the carbon metabolism of fungi; and still less is known about the way in which carbon catabolite repression is integrated with ammonium repression of enzymes involved in nitrogen metabolism.
