摘要
微生物-矿物界面的相互作用贯穿着整个生物浸矿过程,在矿物生物浸出中至关重要,受到微生物的代谢特征、矿物表面结构和物质形态及环境条件的多重交叉影响。研究微生物-矿物界面的相互作用相关的微生物选择性吸附、矿物表面元素形态转化和钝化层、微生物铁硫氧化活性和微生物群落以及胞外物质的组成和性质等的演化,有利于了解微生物-矿物界面作用机制及其关键影响因素和影响机制,从而为优化浸出工艺提供科学的理论依据。达到这些目的,界面的(原位)显微分析手段和技术的进步也至关重要。本文对近些年来上述两方面的研究进行了综述。
Microbe-mineral interfacial interaction plays an important role in bioleaching process. It could be affected by the multi-influential factors among the metabolic characteristic of the microbes, state of the mineral surface structure, chemical speciation and the environmental factors. Researches on selective adsorption of microbes, conversion in mineral surface chemical speciation and passivation layer structure, microbial community and iron/sulfur oxidizing activities, and the composition and properties of extracellular polymer substance can help us to better understand the microbe-mineral interaction mechanism accompanying with its key influential factors and influential mechanism. This researches can also provide scientific base for optimization of the bioleaching techniques. In order to achieve these purposes, the progress in methodology and techniques for in situ（micro） analysis of the interfacial interaction is also pivotal. In this article, we reviewed the progresses on research of microbe-mineral interaction and interfacial micro-analysis in the recent years.
