In natural and engineered environments, microorganisms often co-exist and interact with various minerals or mineral-containing solids. Microorganism-mineral interactions contribute significantly to environmental processes, including biogeochemical cycles in natural ecosystems and biodeterioration of materials in engineered environments. In this mini-review, we provide a summary of several key mechanisms involved in microorganism-mineral interactions, including the following: (i) solid minerals serve as substrata for biofilm development; (ii) solid minerals serve as an electron source or sink for microbial respiration; (iii) solid minerals provide microorganisms with macro or micronutrients for cell growth; and (iv) (semi)conductive solid minerals serve as extracellular electron conduits facilitating cell-to-cell interactions. We also highlight recent developments in harnessing microbe-mineral interactions for biotechnological applications.
在自然环境和工程环境中，微生物常常与各种矿物质或含矿物质的固体共存并相互作用。微生物与矿物质的相互作用对环境过程有重大贡献，包括自然生态系统中的生物地球化学循环以及工程环境中材料的生物劣化。在这篇小型综述中，我们总结了微生物与矿物质相互作用所涉及的几个关键机制，包括：（i）固体矿物质作为生物膜形成的基质；（ii）固体矿物质作为微生物呼吸的电子源或电子受体；（iii）固体矿物质为微生物细胞生长提供大量或微量营养元素；以及（iv）（半）导电固体矿物质作为细胞外电子传导通道促进细胞间相互作用。我们还强调了利用微生物与矿物质相互作用进行生物技术应用的最新进展。
