Microbiologically induced deterioration (MID) causes corrosion of concrete by producing acids (including organic and inorganic acids) that degrade concrete components and thus compromise the integrity of sewer pipelines and other structures, creating significant problems worldwide. Understanding of the fundamental corrosion process and the causal agents will help us develop an appropriate strategy to minimize the costs in repairs. This review presents how microorganisms induce the deterioration of concrete, including the organisms involved and their colonization and succession on concrete, the microbial deterioration mechanism, the approaches of studying MID and safeguards against concrete biodeterioration. In addition, the uninvestigated research area of MID is also proposed.
微生物诱导的劣化（MID）通过产生酸（包括有机酸和无机酸）导致混凝土腐蚀，这些酸会降解混凝土成分，从而损害下水道管道和其他结构的完整性，在全球范围内造成重大问题。了解基本的腐蚀过程和致病因素将有助于我们制定适当的策略，以尽量降低维修成本。本综述介绍了微生物如何诱导混凝土劣化，包括涉及的微生物及其在混凝土上的定殖和演替、微生物劣化机制、研究MID的方法以及防止混凝土生物劣化的措施。此外，还提出了MID尚未研究的领域。
