BIOTRANSFORMATION OF 5-ALPHA-ANDROSTANE-3,17-DIONE BY MICROALGAL CULTURES

Twenty-four different strains of unicellular algae have been used in the bioconversion of 5α-androstane-3,17-dione. 5 α -androstane-3,17-dione has been bioconverted by twenty-four microalgae The activity of algae seems to be species-specific. Reducted, hydroxylated or more unsaturated steroids have been isolated from the cultures.
