title: [Microbial degradation of beta-sitosterol: production of delta 4-androstene-3,17-dione].
abstract: Degradation of the side chain of beta-sitosterol (Ib) gave delta 4-androstene-3,17-dione (II) and a small amount of delta 1,4-androstene-3,17-dione (III) by Mycobacterium vaccae 209-20. The yield of the product II was 32%.
