The selection of the composition of the medium for optimizing the amine-synthetic activity of aerobic bacilli]

Nutrient medium chosen as a basic one after preliminary test of several media known from literature has been optimized to intensify biosynthesis and amine nitrogen production by three strains of aerobic sporulating bacteria to culture liquid. The method of mathematical planning used in the experiments has permitted obtaining the components ratio for the medium on which production of amine nitrogen to the environment increased 2.3-3.2 times. The best variants of the optimized medium promoted an increase of the aminosynthetic activity of the studied bacteria by more than 320%. The obtained nutrient medium is appropriate for a wide screening of aerobic bacilli for their ability to synthesize amino compounds.
