Microbially influenced corrosion (MIC) and biomineralization are widely observed in marine, deep-sea, freshwater, and soil ecosystems. Recently, MIC and biomineralization associated with biofouling have significantly impacted marine resources, including deep-sea minerals and organisms. Notably, uncontrolled biomineralization by certain microorganisms, such as barnacles adhering to ship hulls, can lead to structural damage and economic challenges due to biocorrosion. Biomineralization can be categorized into induced mineralization and controlled mineralization. In natural environments, induced biomineralization is the predominant process. The mechanisms of induced biomineralization and MIC in extreme deep-sea environments have attracted significant attention. The factors influencing these processes are highly complex. The microbial-material interfaces serve as the primary sites for key biochemical reactions driving biocorrosion and biomineralization. Within these interfaces, biofilms, their secreted extracellular polymers, and extracellular electron transfer mechanisms play crucial roles in these processes. Thus, a comprehensive understanding of MIC and biomineralization under deep-sea environmental conditions is essential. Investigating the relationship between these phenomena and exploring their underlying mechanisms are critical for both research advancements and industrial applications.
微生物影响的腐蚀（MIC）和生物矿化在海洋、深海、淡水和土壤生态系统中广泛存在。最近，与生物污损相关的MIC和生物矿化对包括深海矿物和生物在内的海洋资源产生了重大影响。值得注意的是，某些微生物的不受控制的生物矿化，如藤壶附着在船体上，会由于生物腐蚀导致结构损坏和经济挑战。生物矿化可分为诱导矿化和受控矿化。在自然环境中，诱导生物矿化是主要过程。极端深海环境中诱导生物矿化和MIC的机制引起了广泛关注。影响这些过程的因素高度复杂。微生物-材料界面是驱动生物腐蚀和生物矿化的关键生化反应的主要场所。在这些界面内，生物膜、其分泌的胞外聚合物和胞外电子转移机制在这些过程中起着关键作用。因此，全面了解深海环境条件下的MIC和生物矿化至关重要。研究这些现象之间的关系并探索其潜在机制对于研究进展和工业应用都至关重要。
