为了筛选可高效浸出低品位硫化矿的混合菌株,从10个典型的硫化矿矿区的酸性矿坑水中分离富集到混合菌株。以浸出率作为筛选的主要标准,筛选后的高效菌株,利用群落基因组芯片分析混合菌群的组成和过程变化。浸矿持续进行24d后,采集自江西德兴银山铅锌矿的混合菌浸出率最高,为68.89%。群落基因组芯片结果表明银山菌群包含9种菌,可被分为6类,在浸出过程中群落始终在变化。该研究为加速浸出和了解浸出过程中群落演替提供了一个较好的方法。
To screen for a mixed strain that efficiently leached low-grade sulphide ore, mixed strains were isolated and enriched from acidic pit water in 10 typical sulphide ores. Taking the leaching rate as the main screening criteria, the highly efficient strains after screening were used to analyze the composition and process changes of the mixed bacteria population by using the genome genomic chip. After leaching for 24 days, the leaching rate of mixed bacteria collected from Yinxing lead-zinc mine in Dexing of Jiangxi Province was the highest, which was 68.89%. The results of the community genomic chip showed that 9 strains of Yinshan flora were divided into 6 groups, and the community was always changing during the leaching process. This study provides a good way to accelerate the leaching and understand the community succession during the leaching process.
