Microbially influenced corrosion (MIC) of metals exerts a negative effect on the marine environment and causes a great loss of marine facilities. Corrosion prevention in an eco-friendly and sustainable way is a difficult problem to address, especially in the marine environment. In this work, , a corrosive bacteria isolated from the South China Sea was studied by using carbon steel. The results indicate that caused a corrosion loss of 7.68 mg cm and a corrosion pit of 13.0 μm on the carbon steel surface, but the corrosion is inhibited in the presence of sp. EF187016 in the medium. sp. EF187016 preferentially occupied the carbon steel surface, forming a protective biofilm that hindered the attachment of . In addition, extracellular polymeric substances extracted from sp. EF187016 was added to inoculated medium and showed a significant inhibition of MIC on carbon steel.

南海有益生物膜天然有效抑制碳钢微生物腐蚀

金属微生物腐蚀（MIC）对海洋环境造成负面影响，造成海洋设施的巨大损失。以生态友好和可持续的方式预防腐蚀是一个很难解决的问题，特别是在海洋环境中。在这项工作中，利用碳钢研究了从南海分离出来的一种腐蚀性细菌。结果表明，在碳钢表面造成了7.68 mg cm的腐蚀损失和13.0 μm的腐蚀坑，但sp的存在抑制了腐蚀。 EF187016 在介质中。 sp。 EF187016 优先占据碳钢表面，形成保护性生物膜，阻碍 的附着。此外，从 sp. 中提取的细胞外聚合物。将EF187016添加到接种培养基中，对碳钢表现出显着的MIC抑制作用。
