PG - 1185-8 AB - Eubacterium sp. strain VPI 12708 has several bile acid-inducible (bai) genes which encode enzymes in the bile acid 7 alpha-dehydroxylation (7 alpha DeOH) pathway. Twelve 7 alpha DeOH-positive intestinal bacterial strains were assayed for 7 alpha DeOH activity, and 13 strains were tested for hybridization with bai genes. Cholic acid 7 alpha DeOH activity varied greatly (> 100-fold) among these strains. Southern blot experiments showed that DNA prepared from 7 of 13 strains hybridized with at least one of the bai genes from Eubacterium sp. strain VPI 12708.
