生物冶金中耐盐浸矿微生物的研究进展

Salt-tolerant microorganisms in biohydrometallurgy: a review

摘要:

耐盐浸矿微生物是指在发挥矿物浸出功能时对所处的含盐环境具有一定耐受能力的一类浸矿微生物。耐盐浸矿微生物因其可以适应不同浓度的氯化钠等盐，因而在淡水资源缺乏地区的生物冶金中具有广泛的应用价值。本文从耐盐浸矿微生物的种类、耐盐机制及其在矿物生物浸出中的应用现状进行了系统性综述，为耐盐浸矿微生物的研究和应用提供参考。

Abstract:

Salt-tolerant bioleaching microorganism is a kind of microorganism that could survive in the salt-containing environments during bioleaching process. It is found that these species show great application potential in biometallurgy when freshwater resources are scarce. This paper systematically reviews current knowledge and understanding of taxonomic diversity, the salt-adapted mechanisms and the application status of salt-tolerant microorganisms, aiming to provide more information for the research and application of salt-tolerant microorganisms.
