Abstract：
Bioleaching has gained significant attention as a cost-effective and environmentally friendly approach for extracting metals from low-grade ores and industrial byproducts. The application of acidophiles in bioleaching has been extensively studied. Among the various mechanisms leaching microorganisms utilize, quorum sensing (QS) is pivotal in regulating their life activities in response to population density. QS has been confirmed to regulate bioleaching, including cell morphology, community structure, biofilm formation, and cell metabolism. Potential applications of QS have also been proposed, such as increasing mineral leaching rates by adding signaling molecules. This review is helpful for comprehensively understanding the role of QS in bioleaching and promoting the practical application of QS-based strategies in bioleaching process optimization.
摘要：
生物浸出作为一种从低品位矿石和工业副产品中提取金属的具有成本效益和环境友好的方法已经获得了极大的关注。嗜酸菌在生物浸出中的应用已得到广泛研究。在浸出微生物利用的各种机制中，群体感应（QS）对于调节人口密度的生命活动至关重要。QS已经被证实可以调节生物浸出，包括细胞形态学，群落结构,生物膜的形成，和细胞代谢。还提出了QS的潜在应用，例如通过添加信号分子来增加矿物浸出率。该综述有助于全面了解QS在生物浸出中的作用，促进QS策略在生物浸出工艺优化中的实际应用。
