There are some conflicting reports, in the investigation that has been reported, of the ability of different organisms to evolve hydrogen sulphide from various sulphur-containing compounds. One report quite at variance with a majority of others is that of Tanner (1917) who has reported more exhaustive investigation than any other worker, unless it be Sasaki and Otsuka 2 (1912). Tanner, using four per cent of peptone, brand not stated, reports several organisms as producing hydrogen sulphide that other investigators report as negative. Among these are B. paratyphosus A, B. dysentery, B. aerogenes, and Staphyloccus albus. Much of the variation reported, no doubt, is due to the methods used in conducting the investigation. Each investigator has prepared his media according to his own desires, and has employed a concentration often times quite different to that used by others. While this does not make for standard methods it does suggest the extent of influence that substances and concentrations may have upon sulphur metabolism.
