硫（S）是环境和生物体中的关键成分。这项工作是首次尝试对硫氧化细菌（SOB）的作用、机制和环境应用进行概述和批判性讨论。研究结果表明，SOB 的关键酶开始氧化硫化物、亚硫酸盐、硫代硫酸盐和元素 S。还原 S 化合物的转化由各种酶（例如硫化物：醌氧化还原酶、黄素细胞色素 c-硫化脱氢酶、异化亚硫酸盐还原酶、杂二硫键还原酶样蛋白）氧化催化。讨论的 SOB 的环境应用包括硫化氢解毒、土壤生物修复和废水处理。产生 SOB 的 S0 参与生物 S 土壤改良剂（例如盐碱土壤修复、含硫化物矿物的氧化）。使用 SOB 对 H2S 进行生物处理，在好氧和厌氧条件下均发生。通过 SOB 悬浮培养物和基于 S0 的载体去除硫化物、硝酸盐和磺胺甲噁唑。最后，这项工作提出了 SOB 开发的未来前景，包括 S0 回收、SOB 富集、硫化合物的现场测量和鉴定以及数学模拟的发展。

Roles, mechanism of action, and potential applications of sulfur-oxidizing bacteria for environmental bioremediation

Sulfur (S) is a crucial component in the environment and living organisms. This work is the first attempt to provide an overview and critical discussion on the roles, mechanisms, and environmental applications of sulfur-oxidizing bacteria (SOB). The findings reveal that key enzymes of SOB embarked on oxidation of sulfide, sulfite, thiosulfate, and elemental S. Conversion of reduced S compounds was oxidatively catalyzed by various enzymes (e.g. sulfide: quinone oxidoreductase, flavocytochrome c-sulfide dehydrogenase, dissimilatory sulfite reductase, heterodisulfide reductase-like proteins). Environmental applications of SOB discussed include detoxifying hydrogen sulfide, soil bioremediation, and wastewater treatment. SOB producing S0 engaged in biological S soil amendments (e.g. saline-alkali soil remediation, the oxidation of sulfide-bearing minerals). Biotreatment of H2S using SOB occurred under both aerobic and anaerobic conditions. Sulfide, nitrate, and sulfamethoxazole were removed through SOB suspension cultures and S0-based carriers. Finally, this work presented future perspectives on SOB development, including S0 recovery, SOB enrichment, field measurement and identification of sulfur compounds, and the development of mathematical simulation.
