title: [Study of the dynamics of n-propyl alcohol in an Act. erythreus culture during the biosynthesis of erythromycin using a gas-liquid chromatographic method].
abstract: The effect of n-propyl alcohol on biosynthesis of erythromycin and the dynamics of the precursor consumption were studied with the method of gas-liquid chromatography. It was shown that neither the optimal concentration of the precursor, nor its stimulating effect on different media correlated. n-Propyl alcohol was used not only for the antibiotic biosynthesis but also according to other metabolic path-ways and in addition its evaporation from the medium was registered. During the first period of the fermentation n-propyl alcohol suppressed the antibiotic biosynthesis.
