嗜酸性微生物(如氧化亚铁硫杆菌)浸出金属硫化矿已在工业上得到应用,但多用于酸性环境,对中性或碱性环境不适应,而嗜碱性微生物使非酸性条件下的金属浸出成为可能。从不同营养代谢方式对碱性浸矿微生物进行归类,探讨了不同菌种浸出不同类型矿物的作用机制,展望了碱性微生物浸矿研究的发展趋势。
Acidophilic microbes, such as Thiobacillus ferrooxidans, have come into widespread industrial application. However, the acidophilic microbes are notorious inadaptable to neutral or alkaline environment. Alkaline microbes are potential used to leach metallic minerals in non-acid environment. This paper constructs a categorization for alkaline microbes. The mechanism of different alkaline microbes for leaching particular minerals is reviewed, and the research trend is introduced.
