Abstract
The invention concerns a novel method for producing hydroxylated and/or acetylated steroid comprising steps which consist in: culturing yeasts on a medium comprising at least a precursor of such hydroxylated and/or acetylated steroids; then isolating the hydroxylated and/or acetylated steroids from the medium after bioconversion. Said method is characterized in that said yeasts are yeasts transformed so as to express the product of Cyp7b gene. The invention also concerns the modified yeast strains.
