Abstract: | The final parameters of tetracycline biosynthesis in different fermentation apparatus were analysed comparatively with an account of possible changing of the fermentation broth volume against the initial one due to water evaporation. It was shown that for comparison of the biosynthesis parameters in different fermentation apparatus it is necessary to reestimate the activity values or the antibiotic concentration in a unit of the medium volume with respect to the initial volume of the fermentation medium charged into the apparatus. |
