Comparison of bacterial communities in the Baotou Quanshan gold before and after acid leaching

Abstract:

[Objective] Influence on bacterial communities of different ore composition. [Methods] The change of acidic microbial community dominance before and after leaching ore were investigated by using 16S rRNA-RFLP methods. [Results] AMD of three sampling points are the independent Acidithiobacillus bacteria genera of microbes, which accounts for about half the number of tested strains, three sample points between ore leaching microbial species and quantity larger similarity. Meantime, we use the AMD to bioleaching ore, the result of microbial community of four ore samples indicated that H71 and F11 community structure difference are bigger, J72 and S71 are almost the same. [Conclusion] The test sequences can be divided into two branches: Acidithiobacillus bacteria genera and relatively independent bacteria genera.
