[Effect of culture medium components on the biosynthesis of acid ribonuclease by Penicillium brevicompactum cultures].

The effect of different ingredients of the nutrient medium on the synthesis of acid ribonuclease by the culture Penicillium brevi-compactum was studied. The synthesis of RNase reached maximum on the medium containing glucose, pepton, soya bean flour, ammonium sulphate. An excessive content of phosphate in the medium decreased the RNase synthesis. An optimal medium for the synthesis of the enzymes was developed and recommended.
