Not a little work has been done in the past few years in investigating the sulphur metabolism of the colon group of bacteria. So far no very definite conclusions seem to have been arrived at, and the results are rather conflicting. Myers (1920) suggests that hydrogen sulphide production in the intestinal tract is due to proteolytic organisms. He attempted to use hydrogen sulphide production for water analysis, but concludes: "There is no constant relationship between the number of colon bacilli present from different animals and the amount of H2S produced." Other workers have believed the production of hydrogen sulphide in the intestinal tract to be due to the action of B. coli on traces of systine present. B coli is not generally considered a producer of this gas from peptone. Sasaki and Otuska (1912), Berger (1914), and Tanner (1917) report B. coli as giving hydrogen sulphide from cystine.
