为了探明混合浸矿微生物的耐氟特性及其群落动态，构建5株浸矿细菌(Acidithiobacillus ferrooxidans ATCC 23270, Leptospirillum ferriphilum YSK, Sulfobacillus thermosulfidooxidans ST, Acidithiobacills thiooxidans A01, Acidithiobacills caldus S1)的共培养体系。结果表明：氟胁迫在一定程度上抑制了该共培养体系的生长繁殖，对于高浓度的氟胁迫，共培养体系也保持较为平稳的生长延滞状态；氟胁迫对共培养体系硫氧化活性的影响并不明显。采用实时荧光定量 PCR 技术对其培养体系的群落动态进行分析。结果表明，不论是氟胁迫下还是无氟胁迫下， L. ferriphilum YSK和A. caldus S1，都是群...

In order to explore the fluoride tolerance and the community dynamics of mixed bioleaching microorganisms, a co-culture including five typical bioleaching strains (Acidithiobacillus ferrooxidans ATCC 23270, Leptospirillum ferriphilum YSK, Sulfobacillus thermosulfidooxidans ST, Acidithiobacills thiooxidans A01, Acidithiobacills caldus S1) was constructed. The results show that the growth of the co-culture is inhibited by fluoride stress, and the co-culture keeps the stable cell density at high fluoride stress. The sulfur activity of the co-culture is not affected by fluoride stress. Microbial c...
