title: [Determination of the bacterial contamination of nutrient media for the biosynthesis of antibiotics].
abstract: Contamination of separate components of nutrient media used in biosynthesis of antibiotics was tested. It was shown that corn steep liquor, corn and soybean meals were the most contaminated components. The results provided determination of the nutrient media contamination levels by the additive factor with respect to the percentage of the components. The safe period of 2-3 hours for the storage of the nutrient media was determined. After that period the media contamination levels markedly increased.
