The conventional stoichiometry of the oxidation of elemental sulfur by ferric iron in Acidithiobacillus ferrooxidans was not in agreement with our experimental data in terms of ferrous iron and proton formation. Reaction modelling under the actual conditions of bacterial activity resulted in a different stoichiometry, where additional iron species participate in the process to affect the number of released protons. The suggested reaction equation may more accurately predict the intensity of environmental acidification during the anaerobic bioprocess.
嗜酸氧化亚铁硫杆菌中铁离子氧化元素硫的传统化学计量法与我们在亚铁离子和质子形成方面的实验数据不一致。根据细菌活性的实际条件进行反应建模，得到了不同的化学计量，其中额外的铁物种参与该过程，影响释放质子的数量。建议的反应方程式可以更准确地预测厌氧生物过程中环境酸化的强度。
