摘要

研究了油田采出水中硫酸盐还原菌（SRB）对碳钢微生物影响腐蚀（MIC）的抑制机理。在实际油田污水中验证了其实际应用的可行性。B. velezensis显著减少了无根SRB种群，抑制SRB生物膜在碳钢表面的发育。因此，28天内腐蚀速率降低了93 %。B. velezensis显示出干扰SRB介导的生物催化阴极硫酸盐还原过程的能力，这种影响归因于B. velezensis释放的多种抗菌代谢物。

A novel biological control strategy for microbiologically influenced corrosion in oilfield produced water based on Bacillus velezensis

The inhibition mechanism of Bacillus velezensis against microbiologically influenced corrosion (MIC) of carbon steel by sulfate reducing bacteria (SRB) in oilfield produced water was investigated. The feasibility of its practical application was validated in real oilfield sewage. B. velezensis markedly diminished the population of sessile SRB and suppressed the development of SRB biofilms on the carbon steel surfaces. The corrosion rate was consequently reduced by 93 % within 28 days. B. velezensis demonstrated the ability to interfere with the biocatalytic cathodic sulfate reduction process mediated by SRB, an effect attributable to the diverse antimicrobial metabolites released by B. velezensis.

期刊介绍： Corrosion occurrence and its practical control encompass a vast array of scientific knowledge. Corrosion Science endeavors to serve as the conduit for the exchange of ideas, developments, and research across all facets of this field, encompassing both metallic and non-metallic corrosion. The scope of this international journal is broad and inclusive. Published papers span from highly theoretical inquiries to essentially practical applications, covering diverse areas such as high-temperature oxidation, passivity, anodic oxidation, biochemical corrosion, stress corrosion cracking, and corrosion control mechanisms and methodologies. This journal publishes original papers and critical reviews across the spectrum of pure and applied corrosion, material degradation, and surface science and engineering. It serves as a crucial link connecting metallurgists, materials scientists, and researchers investigating corrosion and degradation phenomena. Join us in advancing knowledge and understanding in the vital field of corrosion science.
