THE RELATIONSHIP BETWEEN THE PROPERTIES T RANSFER IN INDUSTRIAL BIOREACTORS AND PENICILLIN BIOSYNTHESIS

This paper presents an analysis of the hydrodynamic and mass transfer conditions in an abiotic system and in the abiotic system and in the p enicillin biosynthesis performed in industrial bioreactors provided wi th classical and modified Rushton turbine agitation, The bioreactors u sing modified agitators create a hydrodynamic microclimate favourable to the penicillin culture, by actually increasing the well agitated ar ea, the oxygen mass transfer rate, the fluid pumping efficiency and th e micelles life scission frequency.
