[Extracellular amino acids of aerobic spore-forming bacteria].
An ability to synthesize and accumulate in the growth medium for extracellular amino acids of 108 strains of 13 aerobic sporeforming bacteria species at deep cultivation on the simple synthetic glucose-mineral liquid nutrient medium optimized for the representatives of this genus. Has been studied the bacillus strains studied in the present conditions synthesize 19 amino acids and 2 amino carbons in different quantities and combinations. Amino acids being synthesized the most and least by these microorganisms have been determined in quantitative expression. Extracellular amino acid accumulation was proved to be a strain property not of genus. In general, the genus studied was evaluated as active one in amino acid production. The most active strains may present an interest as initials for further selective obtaining of producers of separate amino acids. The outlook for aerobic bacilli strains having marked amino-synthesizing properties and complex of other biological activities is being discussed for construction of medicinal and prophylactic of live microbial culture preparations.
