Abstract

By preselection of microorganisms which preferentially attack the side chain of cholesterol we have been able to isolate a mutant of Corynebacterium spec. Chol 73 which forms 20-carboxy-pregna-1,4-dien-3-one (BNC) from cholesterol in nearly quantitative yields. The structure of this compound has been established by means of13C NMR-,1H NMR and CD spectroscopy.
