Degradations of 4‐cholesten‐3‐one and 1,4‐androstadiene‐3,17‐dione, which are intermediates of microbial conversion of cholesterol, by cholesterol‐degrading bacteria (12 strains of the genus Rhodococcus isolated from food of animal origin and 12 culture collection strains) were examined. All strains had the ability to degrade 4‐cholesten‐3‐one without necessarily being able to degrade cholesterol. On the other hand, the bacteria were divided into three groups with little or no (0–10%), intermediate (10–70%) and high (70–100%) degradation abilities for 1,4‐androstadiene‐3,17‐dione.
