Abstract:The effect of the aeration rate on biosynthesis of carminomycin by Actinomadura carminata and biochemical changes in the fermentation broth on the use of 3 complex media of different composition was studied. The carminomycin-producing organism can grow and produce the antibiotic within the ranges of the aeration changes from 0.98 to 18.56 mgO2/1-min. A decrease in the maximum rate of oxygen dissolution up to 0.98 mgO2/1-min resulted in some decrease in the activity level. Intensive aeration, i.e. 18.56 mgO2/1-min induced suppression of the antibiotic production by 25 per cent.
