浸矿细菌——喜温硫杆菌研究进展

摘要

生物冶金技术具有良好的发展前景.喜温硫杆菌是生物冶金过程中的优势浸矿菌之一,在混合浸矿体系中可协助铁氧化细菌显著提高浸矿效率.本文在分析相关文献的基础上,并结合本实验室的研究工作,从喜温硫杆菌在浸矿过程中的作用机制、抗砷机制、基因组学研究和遗传改造等方面的研究进展进行了综述,并对未来相关研究方向做了展望,旨在为喜温硫杆菌研究提供参考.%Acidithiobacillus caldus (A .caldus) is one of the predominant biomining bacteria, which shows application prospect in biological metallurgy. It can enhance the biomining efficiency together with iron oxidation bacteria in mixed biomining system.Based on the published papers and our study on this bacterium; we described the research progress on it from four aspects; including the biomining mechanism; arsenic-resistant mechanism; genome study and genetic reconstruction. Furthermore; we discussed the prospects of research on A . caldus .
