Corrosion of stainless steel by Desulfovibrio species through end-to-end connection attachment
Source abstract
Abstract
Electron transport via sulfate-reducing bacteria (SRB) is a major cause of anaerobic corrosion. In this study, we elucidated the attachment process and metabolic mode of Desulfovibrio bizertensis SY-1 on 316L SS via surface analysis and transcriptomic. Surface morphology observation revealed D. bizertensis could survive on SS surfaces for long time through end-to-end connections. Reducing the carbon source in the medium decreased the time needed to form these end-to-end connections and increased their length, creating more obvious pitting on the coupons. Gene expression found that attached cells obtained energy mainly through oxidative phosphorylation and the oxidation of succinate, while sulfate reduction genes were downregulated. These findings further expand our understanding of SRB biofilm and metabolic mechanism.
