[Effect of the aeration conditions on the biosynthesis of oxytetracycline and the formation of organic acids by a culture of Actinomyces rimosus].
The effect of the aeration conditions on oxytetracycline biosynthesis and production of organic acids by Act. rimosus was studied. Intensive biosynthesis of oxytetracycline in shaken flasks with concentrated complex media was observed at the rate of oxygen dissolution in the liquid ranging from 14 to 25 mg/1/min. Lower rates of the oxygen dissolution up to 7 mg/1/min resulted in decreased rates of the culture growth and the medium component consumption, decreased antibiotic levels, production of significant amounts of pyruvic and acetic acids.
