摘要
铜尾矿中硫化物成分被生物氧化，是高危险性酸性矿山废水的来源之一。本研究利用印度Malanjkhand铜矿项目(MCP)尾矿样品，采用基于16S rRNA基因扩增子测序(靶向V4区)的方法，了解微生物群落组成和产酸潜力。3个理化性质不同的尾矿样品(T1、T2和T3)显示出不同的微生物组合。最极端性质(pH <2.0)中有变形菌门、放线菌门、氯氟菌门，而样品(T1和T3)的性质略中等(pH <4.0和>3.0)显示丰富的变形菌门，有限菌门，放线菌门和/或硝化螺旋菌。宏基因组序列可在BioProject ID PRJNA361456下获得。
Metagenomic exploration of microbial community in mine tailings of Malanjkhand copper project, India
Mine tailings from copper mines are considered as one of the sources of highly hazardous acid mine drainage (AMD) due to bio-oxidation of its sulfidic constituents. This study was designed to understand microbial community composition and potential for acid generation using samples from mine tailings of Malanjkhand copper project (MCP), India through 16S rRNA gene based amplicon sequencing approach (targeting V4 region). Three tailings samples (T1, T2 and T3) with varied physiochemical properties selected for the study revealed distinct microbial assemblages. Sample (T3) with most extreme nature (pH < 2.0) harbored Proteobacteria, Actinobacteria, Chloroflexi while the samples (T1 and T3) with slightly moderate nature (pH < 4.0 and > 3.0) exhibited abundance of Proteobacteria, Fimicutes, Actinobacteria and/or Nitrospirae. Metagenomic sequences are available under the BioProject ID PRJNA361456.
