title: Enhancement of the 7 alpha-dehydroxylase activity of a gram-positive intestinal anaerobe by flavins.
abstract: The addition of flavins to the growth medium specifically enhanced the 7alpha-dehydroxylation of bile acids by anaerobically growing cultures of a Eubacterium lentum-like intestinal anaerobe, strain c-25, without an increase in cell growth. The order of the enhancement of the reaction was flavin adenine dinucleotide > flavin mononucleotide >> riboflavin.
