以前已经证明，化学自养和兼性厌氧菌，脱氮硫杆菌，可以在间歇和连续的H_2S(G)反应器中，在硫化物限制的条件下进行好氧或厌氧培养。提出了一种脱除气体中H_2S的新工艺--脱氮曲霉氧化H_2S。本文描述了其他硫杆菌对H_2S氧化的研究，其目的是确定其他硫杆菌在有氧氧化H_2S方面是否比脱氮硫杆菌有任何优势。尽管其他四种硫杆菌被发现以硫化氢为能源生长，但没有一种细菌比脱氮硫杆菌有明显的优势。
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 H2S(g) under sulfide‐limiting conditions. A process has been proposed for the removal of H2S from gases based on oxidation of H2S by T. denitrificans. Described here is a study of H2S oxidation by other Thiobacilli, the purpose of which has been to determine whether other Thiobacilli offer any advantages over T. denitrificans in the aerobic oxidation of H2S. Although four other species of Thiobacillus were found to grow on H2S as an energy source, none offer a clear advantage over T. denitrificans.
