Oxidation of hydrogen sulfide by Thiobacilli.

It has been previously demonstrated that the chemoautotroph and facultative anaerobe, Thiobacillus denitrificans, may be cultured aerobically or anaerobically in batch and continuous reactors on H(2)S(g) under sulfide-limiting conditions. A process has been proposed for the removal of H(2)S from gases based on oxidation of H(2)S by T. denitrificans.
