简介：在过去的十年，biohydrometallurgy的领域里的进步是重要的。17新奇biomining微生物的一个总数被发现，并且八铜堆bioleaching种并且11黄金biooxidation植物被建立或膨胀。在这评论，它被总结为学习微生物引起的社区动力学和结构的最新孤立的biomining微生物和三个新奇微生物引起的生态的方法的生理的性质。另外，关于象铀，铝，碲，金者，铟，和第二等的稀罕金属资源那样的稀罕金属的biohydrometallurgy研究，以及象铜，镍，钴，和黄金那样的重非铁的金属被考察了，与在中国的一个重音。在未来，黄铜矿，稀罕金属，从废物的第二等的资源，和资源利用引起的环境污染的bioleaching上的进一步的研究是必要的。图形的AbstractZijinshan堆bioleaching植物与30,000的能力在2012重启操作?tonent蠨?蠨吗？？

简介：二酸矿排水(AMD)样品TS和WK，从在Guangxi省的Dachang充满金属的矿，中国，用基于PCR的克隆被学习途径。44个运作的分类单位(OTU)的一个总数从二件AMD样品被获得。然而，仅仅三OTU(GXDC-9，GXDC-19和GXDC-50)在样品TS检测了能也在样品WK被观察。种系发生的分析表明在二件样品的细菌掉进四个通常认为的部门，它是Nitrospira，Alphaproteobacteria，Gamaproteobacteria，和Acidobacteria。类Acidithiobacillus和Leptospirillum的有机体，在gamaproteobacteria班和Nitrospira家庭上，分别地在二件样品是主导的。在样品TS，它被低pH描绘，高硫酸盐，高铁，和高砷化物，二种(Acidithiobacillusferrooxidans和Leptospirillumferrooxidans)组成了98.22%全部微生物引起的社区。与样品TS相比，在样品WK的微生物引起的社区根据观察是更多样化的。抱持兴趣地，Legionella种类，很少在low-pH环境被观察，在样品WK被检测。这个工作帮助我们进一步理解微生物引起的社区与唯一的地球化学和acidophiles的忍耐能力在极端酸矿排水住在一起到重金属的差异。
