硫氧化菌在碱性尾矿中的适应机制与生态修复作用研究进展
A Review of Advances in Understanding the Adaptation Mechanisms and Ecological Functions of Sulfur-Oxidizing Bacteria in Alkaline Tailings
摘要
Abstract
Alkaline mine tailings(pH>8),predominantly derived from the flotation of iron,aluminum,and molybdenum ores,are characterized by high salinity,nutrient deficiency,low organic matter,and poor structural integrity.These extreme physicochemical conditions impede natural recovery processes and pose long-term environmental and health risks.Conventional remediation measures,such as topsoil coverage and chemical stabilization,have demonstrated limited efficacy in such contexts,necessitating alternative strategies with enhanced ecological compatibility.Sulfur-oxidizing bacteria(SOB),recognized for their metabolic plasticity and environmental resilience,have shown significant potential in the bioremediation of extreme substrates.Recent advances in understanding SOB distribution and adaptation mechanisms in alkaline tailings are synthesized in this review,including diversified sulfur metabolism,utilization of alternative electron acceptors,stress response to salinity and metal(loid)s,biofilm development,and regulation of functional gene expression.Furthermore,the roles of SOB in improving alkaline tailing physicochemical properties,promoting soil structure formation,enhancing organic matter stabilization,and facilitating metal(loid)s immobilization are systematically evaluated.Key environmental factors influencing SOB activity are also discussed.A conceptual framework integrating physicochemical function,nitrogen and carbon fixation,and ecosystem build-up is proposed to support SOB-based mine tailing rehabilitation technologies.Research gaps and future directions for SOB application in ecological rehabilitation of alkaline tailings are proposed.The BRIEF REPORT is available for this paper at http://www.ykcs.ac.cn/en/article/doi/10.15898/j.ykcs.202505050113.关键词
