[Characteristics of the process of regulated biosynthesis of oxytetracycline].

Investigation of the process of oxytetracycline biosynthesis in a model medium showed that addition of maltose during the phase of antibiotic biosynthesis resulted in an increase in the rate of the culture growth, prolongation of the antibiotic production phase and increased productivity of the mycelium. The productive mycelium was characterized by a higher content of total nitrogen and phosphorus.
