ABSTRACT:
The side chains of sterols are degraded by fermentation with microorganisms capable of doing so in an improved manner by employing in such fermentations sterol derivatives of the formula ##STR1## wherein n is 1 or 2; R.sub.1 is H or lower alkyl, R.sub.2 is alkyl, whose chain optionally is interrupted by an oxygen atom, or when n is 2, also a hydrogen atom; and R.sub.3 is a sterol side chain.
