FIELD: biotechnology, microbiology.
SUBSTANCE: invention proposes a nutrient medium containing components chosen in the following ratio, g/1 l: casaminic acids, 10-12; yeast extract, 3-5; potassium hydrogen phosphate, 7-8; magnesium sulfate, 0.1-0.2; sodium citrate dihydrate, 0.5-0.6; ammonium sulfate, 2-2.5, and glucose, 1-2. Using a liquid nutrient medium provides the intensive growth of staphylococci since first hours of cultivation and allows attainment of maximal yield of antibacterial compound after 8 h growth of culture. Invention is designated for culturing staphylococci in aim for preparing antibacterial peptide compounds.
EFFECT: improved and valuable properties of nutrient medium.
