Sulfate-reducing bacteria (SRB), which couple oxidation of organic carbon or hydrogen to reduction of sulfate to sulfide, are widespread in anaerobic soils and sediments and are key catalysts in the global carbon and sulfur cycles. The impact of SRB in resource-based industries is profound and can be positive (mining: remediation of acid waste) or negative (oil and gas: corrosion and lowering of product quality). The study of SRB is facilitated by the fact that several genome sequences are now available, including that of Desulfovibrio vulgaris Hildenborough (DvH), isolated from anaerobic clay soil.

硫酸盐还原菌（Sulfate-reducing bacteria，SRB）广泛存在于厌氧土壤和沉积物中，是全球碳、硫循环的关键催化剂。硫酸盐还原菌对资源型工业的影响是深远的，可能是积极的（采矿：酸性废物的补救），也可能是消极的（石油和天然气：腐蚀和降低产品质量）。硫酸盐还原菌的研究是由几个基因组序列，包括脱硫弧菌的Hildenborough（DvH），从厌氧粘土分离的事实，现在可用。
