| 微生物腐蚀（microbiologically influenced corrosion，MIC）是海洋环境中一种非常重要的腐蚀形式，其是微生物、环境、材料共同作用的结果，本文自MIC对海洋环境、菌株、材料性质的依赖性三个方面概述其机理的研究进展。在MIC对海洋环境的依赖性方面，突出溶解氧浓度和营养水平的影响规律与机制。在MIC对菌株的依赖性方面，首先介绍典型单菌株的腐蚀影响机制，然后分析混合菌株间不同菌株的腐蚀协同与拮抗作用，最后阐述复杂微生物群落的影响。在MIC对材料性质的依赖性方面，在总结基体化学成分与结构影响的基础上，介绍对MIC有抑制作用的典型表面的特性及其作用机制。 |

| Abstract: |
| Microbilogically influenced corrosion (MIC) is a very substantial corrosion pattern in marine environment, and it is a joint consequence of microorganism, environment, and material factors. In this paper, we reviewed the research progress on MIC mechanisms from the aspects of marine environment, bacterial strains, and material characteristics. The impact rules and function mechanisms of dissolved oxygen concentration and nutrient level were focused in the view of marine environment dependence of MIC. For the dependence of MIC on bacterial strains, the corrosion impact mechanisms of typical pure strains were introduced, and then corrosion synergistic and antagonism among different strains in mixed cultures were analyzed. The effect of microbial communities with complex structures was described. In addition, dependence of MIC on material characteristics was discussed from two aspects:substrates and surfaces. To our understanding, the former is related to chemical compositions and structures of substrates, while the latter refers to the mechanisms of the features and functions of typical surfaces inhibiting MIC. |
