摘要：
Mutants which are used in a novel microbiological process to selectively degrade steroids having 17-alkyl side chains of from 2 to 10 carbon atoms, inclusive, to androsta-1,4-diene-3,17-dione (ADD) and androst-4-ene-3,17-dione (AD). ADD and AD are valuable intermediates to make useful steroids.
