Abstract
The effect of various concentrations of ammonium sulfate, sodium and potassium chlorides and sulfates on biosynthesis of polymyxin M by Bac. polymyxa Ross. on media containing wheet meal as the carbon source was studied. The culture growth, antibiotic accumulation and consumption of the main nutrients was studied as dependent on the level of the salts in the medium. The highest productivity was observed on media with the salt concentrations amounting to 1--2 per cent except sodium sulfate: changes in the concentration of the latter had practically no effect on the activity of the fermentation broth.
