It is well accepted that biodiversity and ecosystem functions are strongly shaped by environmental conditions; however, relatively little is known about how they depend on the mineralogical assemblage of local environments, especially in mines. This study aims to reveal the diversity characteristics of the fungal community in the surface of granite lithium ores and their weathering products sampled from the Yifeng lithium mines in Jiangxi Province, eastern China. According to the analysis of internal transcribed spacer1 (ITS1) high-throughput sequencing, significant differences in fungal community diversity on the surface of lithium ores and their weathering products have been revealed. The operational taxonomic unit (OTU) of the ore surface and its weathering products ranged from 280 to 624, which may depend on the mineral composition as well as the degree of weathering. The community composition of each sample was significantly different at the phylum level, especially between the weathering products in Ascomycota and Basidiomycota. Although Ascomycota and Basidiomycota were the dominant fungal communities in all samples, each sample has its own distinctive fungi. The trophic modes of the fungi were more complex than that of the bacteria. 10 different fungal trophic modes and 25 dominant functional fungal groups were disclosed, and the saprophytic community was found to be the dominant group. These fungi could accelerate the decomposition of environmental organic matter in the environment by producing hydrolases and oxidases. Chytridiomycota with the function of producing and regulating secondary metabolites were the representative fungi in all samples. Our findings would provide theoretical basis and research clues for understanding the relationship between weathering of granite lithium and fungal communities.
人们普遍认为，生物多样性和生态系统功能受到环境条件的强烈影响；然而，人们对它们如何依赖于当地环境的矿物组合，尤其是在矿山中，知之甚少。本研究旨在揭示中国东部江西省宜丰锂矿表面花岗岩锂矿石及其风化产物中真菌群落的多样性特征。根据内部转录间隔区 1（ITS1）高通量测序分析，揭示了锂矿石及其风化产物表面真菌群落多样性的显著差异。矿石表面和其风化产物的操作分类单元（OTU）范围从 280 到 624，这可能取决于矿物组成和风化程度。在门水平上，每个样本的群落组成差异显著，尤其是在风化产物中的子囊菌门和担子菌门之间。尽管子囊菌门和担子菌门是所有样本中占主导地位的真菌群落，但每个样本都有其独特的真菌。真菌的营养模式比细菌更复杂。揭示了 10 种不同的真菌营养模式和 25 种主要的功能真菌群，发现腐生菌是主要群体。这些真菌可以通过产生水解酶和氧化酶来加速环境中环境有机物质的分解。产生活性物质和调节次生代谢物的壶菌门真菌是所有样本中的代表性真菌。我们的研究结果将为理解花岗岩锂风化与真菌群落之间的关系提供理论依据和研究线索。
