| 摘要 |
Acid mine drainage (AMD) environments are typically used as models to study the crucial roles of acidophilic microbes in aquatic environments. Nevertheless, knowledge regarding microbial-driven biogeochemical cycling across mining regions remains limited. In this study, a metagenomics-based approach was employed to explore the diversity, composition, and ecological functions of microbiomes in global AMD environments with different mineral types. A total of 226 metagenomes, covering 12 mineral types of AMD, were analyzed. As a result, 2114 microbial metagenome-assembled genomes (MAGs) were obtained, representing members from 33 bacterial phyla and 8 archaeal phyla. The core taxa and functional groups in AMDs were identified. Additionally, twelve bacterial and two archaeal lineages were discovered for the first time in AMD environments. The specific metabolic potentials of these genomes were also determined. Our results revealed a high level of specialization in the diversity structures and ecological functions of AMD microbial communities based on mineral-type conditions. Mineral type significantly contributed to the dissimilarity in the AMD microbiomes, especially in water environments, underscoring the pivotal role of mineral types in shaping the microbial community in the AMD environment. Collectively, these findings provide novel perspectives on the ecology and metabolism of micro- biomes in extreme AMD environments globally. |
