Abstract
Proteolytic enzymes with coagulase activity were found in the cultural broth of Bacillus subtilis var. amyloliquefaciens 759 grown on chemically defined and natural media. The effect of various sources of carbon, nitrogen and phosphorus on biosynthesis of proteases with coagulase activity was studied; mineral and organic nitrogen sources were equally favourable for the growth and protease biosynthesis. The best sources of carbon for biosynthesis of the enzymes were glucose, sucrose, maltose, fructose, and sorbitol. Potassium salts of ortho-phosphoric acid were assimilated as a source of phosphorus.
