摘要	Biocorrosion in marine environments is often associated with biofilms of sulfate reducing prokaryotes. However, the corrosion behaviors of steel differed greatly between the bacterial species. In this study, six strains of sulfate reducing prokaryote including 3 strains of strictly anaerobic bacteria and 3 strains of facultative anaerobic bacteria were isolated from the steel rust immersed in Sanya, China. The corrosion behavior of Q235 carbon steels by isolated six strains was studied by weight loss analysis, electrochemistry measurements, and surface morphology observation. In addition, the relationship between bacterial corrosivity and strain type was investigated. The results indicated that there is no direct relationship between the corrosivity of bacteria and strain type, whether the bacteria were strictly anaerobic or not. The corrosion rates of steel coupons fluctuated with the strain properties and soaking time. Among the strains tested, the strains belonging to Proteobacteria had relatively high corrosion rates on steel coupons, whereas, strain Virgibacillus Dokdonensis of Firmicutes has the lowest corrosion rate. The results provide a guiding basis for exploring the mechanism of microbial corrosion and controlling marine microbial corrosion.
