Microbial transformation of dehydrocholic acid into steroid dimers containing the benzene ring
Abstract
Dehydrocholic acid has been converted by Streptomyces gelaticus into steroid dimers (4,4′ : 6,6′- or 4,6′ : 4′,6-bisteroids) in which carbon atoms 4, 4′, 5, 5′, 6, and 6′ comprise a benzene nucleus.
