Abstract
Studies on supporting medium composition and its feed rate were performed i n order to maintain stationary biomass concentration during the process of progesterone hydroxylation with Rhizopus nigricans pellets. Growth kinetic parameters were evaluated for two media with different nitrogen sources. Th e results indicate the benefit of using complex media at higher feed rates than those used for the maintenance of stationary biomass concentration wit hout exogenous steroid addition.
