本文简述了能将硫代硫酸盐还原成硫化氢（H2S）的严格厌氧菌的重要特征。虽然在微生物界，硫代硫酸盐的还原作用是一种普通的新陈代谢作用，但它与微生物腐蚀之间的潜在关系未见过报道，硫代硫酸盐一般存在于硫化氢与氧气共存的生态系统中。本文以几内亚海湾的一条含硫原油管道为例说明这个问题，一年的时间，这条管线的点蚀深度达1cm。 This article outlines the key features of a strictly anaerobic bacteria capable of reducing thiosulfate to hydrogen sulfide (H2S). Although the reduction of thiosulfate is a common metabolic activity in the microbial community, the potential relationship between it and microbial corrosion has not been reported, and thiosulfate is generally found in ecosystems where hydrogen sulfide and oxygen coexist in. In this paper, a sulfur-containing crude oil pipeline in the Gulf of Guinea is used as an example to illustrate this problem. The pitting depth of this pipeline reaches 1 cm in a year.
