Fungi play an important role in bioremediation of contaminated soil. However, the diversity of fungal populations in four mine-contaminated soils located in Hechi City has remained unexplored. In this study, high-throughput sequencing of ITS was performed to investigate the diversity and abundance of fungal communities in four mine-contaminated soils in Hechi city. Phylogenetic taxonomy showed that the fungal communities included five phyla. Ascomycota and Basidiomycota were the most abundant phyla in four samples. The most abundant fungi included Agaricomycetes , Nectriaceae , Eurotiomycetes , Mortierellaceae , Incertae sedis , Trichocomaceae , Sordariomycetes , and Fusarium . Various fungi with the potential of bioremediation and industrial application were discussed. The results of fungal composition will provide a clue for isolation of new fungi with the potential of bioremediation and industrial application. Furthermore, this study will lay a good foundation for modifying the indigenous fungi by genetic engineering in the future.

河池市矿山污染土壤真菌成分分析

真菌在污染土壤的生物修复中发挥着重要作用。然而，河池市四个受矿山污染的土壤中真菌种群的多样性仍未得到探索。本研究对河池市4个矿山污染土壤中真菌群落的多样性和丰度进行了ITS高通量测序。系统发育分类学表明真菌群落包括五个门。子囊菌门和担子菌门是四个样品中最丰富的门。最丰富的真菌包括伞菌纲、Nectriaceae、Eurotiomycetes、Mortierellaceae、Incertae sedis、Trichocomaceae、Sordariomycetes 和 Fusarium。讨论了具有生物修复和工业应用潜力的各种真菌。真菌组成的结果将为分离具有生物修复和工业应用潜力的新真菌提供线索。此外，本研究将为今后通过基因工程改造本土真菌奠定良好的基础。
