The paper is dedicated to selecting main components of the nutrient medium and additional sources of nutrients for the maximum production of adamalysin-like metalloproteinase Bacillus pumilus. For convenience, the gene of metalloproteinase MprBp was cloned in protein-deficient strain B. subtilis BG2036. During the study, optimal concentration of peptone, inorganic phosphate, and casein was selected. Besides, it was shown that the enzyme production is stimulated by kasamino acids, leucine, alanine, asparagine, glutamine, as well as calcium and magnesium ions.
