摘　　要：在 Zijinshan 商业低档铜 bioleaching 堆的矿石表面的微生物引起的社区结构被 16S rRNA 基因克隆图书馆调查。为细菌和 Archaea， 105 克隆被定序。在矿石表面在场的主导的细菌种类是 Acidithiobacillus 和 Leptospirillum，为 51.42% 和 48.57% 的财务分别地。然而为 Archaea，仅仅一个运作的分类单位(外面) 属于 Ferroplasma acidiphilum。这些结果显示在商业低档铜 bioleaching 堆的类 Acidithiobacillus 的那功能可以被低估。详细说明的更多和微生物引起的社区结构的量的信息现在随着时间的过去在调查下面。The microbial community structure in the ore surface of Zijinshan commercial low-grade copper bioleaching heap was investigated by 16S rRNA gene clone library. For both bacteria and Archaea, 105 clones were sequenced. The dominant bacteria species present in the ore surface were Acidithiobacillus and Leptospirillum, accounting for 51,42% and 48.57%, respectively. However, for the Archaea, only one operational taxonomic unit （OUT） belonged to Ferroplasma acidiphilum. These results indicate that function of genus Acidithiobacillus in the commercial low-grade copper bioleaching heap may be underestimated. More detailed and quantitative information on microbial community structure over time are now under investigation.
