摘要

Microbiologically influenced corrosion (MIC), driven by the bacterial metabolic process, severely degrades multiple metallic materials. Metal degradation causes significant economic losses in various industrial sectors. In order to maintain the integrity of the structure, efficient MIC inhibition strategies are indispensable. Conventionally, synthetic inhibitors have been used to suppress MIC. In spite of their effectiveness, the toxicity and environmental threats associated with synthetic inhibitors have led to the development of eco-friendly inhibitors. This publication delves into the paucity of MIC inhibition strategies for alumnium alloys through green corrosion inhibitors. The review highlights MIC inhibition mechanism using plant-based extracts and beneficial microbes. Further, the review emphasizes the role of phytochemicals targeting bacterial efflux pumps and disrupting its défense mechanisms. Additionally, plant-based extracts and beneficial microbes as quorum sensing inhibitors in suppressing biofilm formation is reviewed. It also discusses life cycle assessment (LCA) concerns of green versus conventional inhibitors, highlighting sustainable MIC mitigation needs.
