Optimization of cultivation medium for the production of Bacillus intermedius 3-19 glutamyl endopeptidase | Optimizatsiia sredy kul'tivirovaniia dlia produktsii glutamiléndopeptidazy Bacillus intermedius 3-19.

The effect of some components of cultivation medium on the growth of the streptomycin-resistant Bacillus intermedius strain 3-19 and on the production of glutamyl endopeptidase was investigated using factorial experimental design, which allowed the concentrations of peptone and inorganic phosphate to be optimized for the maximum production of the enzyme. Experiments with different peptones and casamino acids showed that the enzyme production is maximum with peptone 3 of plant origin. The addition of casamino acids or amino acids to the peptone-containing cultivation medium inhibited the production of glutamyl endopeptidase

Hydrolytic enzymes and spore formation in Bacillus intermedius | Gidroliticheskie fermenty i sporoobrazovanie u Bacillus intermedius.

The investigation of the activity of extracellular hydrolytic enzymes and sporulation in the bacterium Bacillus intermedius 3-19 showed that the activity of ribonuclease is maximal in the glucose-containing growth medium, in which sporulation is suppressed. At the sporulation stages II-IV, the synthesis of phosphatase was not regulated by the factors that influence this synthesis in the phase of growth retardation. Caseinolytic activity exhibited two peaks. The first peak was observed when thiol-dependent proteinase began accumulating in the medium. The second peak corresponded to the late stages of sporulation, i.e., the stages of spore maturation and the autolysis of sporangium. The regulatory relationship between proteinase synthesis and sporulation and the possible role of extracellular phosphatases and proteinases in the sporulation are discussed
