Kinetics of alkaline protease production by Streptomyces griseoflavus PTCC1130
BACKGROUND AND OBJECTIVES Proteases are a group of enzymes that catalyze the degradation of proteins resulting in the production of their amino acid constituents. They are the most important group of industrial enzymes which account for about 60% of total enzymes in the market and produced mainly by microorganisms. The attempts were made to study the kinetic parameters of protease produced by S...
متن کاملRestoration of aerial mycelium and antibiotic production in a Streptomyces griseoflavus arginine auxotroph.
An arginine auxotrophic mutant was obtained from Streptomyces griseoflavus (bicozamycin-producing strain). The mutant grew on synthetic agar supplemented with either arginine, ornithine, citrulline or argininosuccinate, but produced massive aerial mycelium and bicozamycin only with citrulline. In liquid culture, citrulline also completely restored the ability of the mutant to produce bicozamyci...
متن کاملGenome sequence of an industrial microorganism Streptomyces avermitilis: deducing the ability of producing secondary metabolites.
Streptomyces avermitilis is a soil bacterium that carries out not only a complex morphological differentiation but also the production of secondary metabolites, one of which, avermectin, is commercially important in human and veterinary medicine. The major interest in this genus Streptomyces is the diversity of its production of secondary metabolites as an industrial microorganism. A major fact...

متن کاملMetabolic products of microorganisms. 246. 2880-II, a metabolite related to ferulic acid from Streptomyces griseoflavus.
By chemical screening methods we detected in the mycelium of Streptomyces griseoflavus (strain Tii 2880) the colabomycin-complex2) and a second compound, called 2880-ll (Rf values see Table 1). 2880-ll absorbed UV light on Silica gel F254, and turned black with molybdatophosphoric acid and dark brown with vanillinsulfuric acid. It could be separated from the crude extracts by silica gel chromat...
