[Effect of the growth conditions for the inoculum on cephalosporin biosynthesis].

It was shown that intensification of cephalosporin biosynthesis is possible with the use of the inoculum grown on the seed medium enriched with the sources of carbon and organic nitrogen. The inoculum grown on the initial medium is usually added to the fermentation medium by the 31st-33rd hour of the growth, while with the use of the enriched medium it is added to the fermentation medium by the 36th-38th hour. The intensity of the culture respiration is recommended to be used as a technological parameter for estimation of the time when the inoculum may be added to the fermentation medium.
