The oxidation of tritium gas (HT) by fecal suspensions from rat, monkey and man was measured under aerobic and anaerobic conditions. In any case tested, the HT oxidation activity in fecal suspension under anaerobic conditions was almost the same among animals and man and remarkably higher than that under aerobic conditions. In order to understand what kinds of bacteria actually oxidize HT in the intestine, a number of bacterial strains were isolated from rat and human feces by using various media for isolation and selection of intestinal anaerobes. Among the isolates, 27 strains derived from rat feces and 63 strains from human feces were found to oxidize HT under anaerobic conditions. Most of them were identified as some species of Bacteroides, Fusobacterium, Veillonella or Clostridium, and some of them were facultative anaerobes and identified as Escherichia coli. HT oxidation activity of Veillonella was highest. All strains identified as Lactobacillus acidphilus, L. plantarm of Bifidobacterium adlescentis did not oxidize HT.
