Subsidence from coal mining is a major environmental issue, causing significant damage to soil structure. Soil microorganisms, highly sensitive changes, adapt accordingly. This study focused on four areas of the Burdai mine: non-subsidence area (CK), half-yearly (HY), 1-year (OY), and 2-year (TY) subsidence areas. Using high-throughput sequencing molecular ecological network analysis, we examined microbial community diversity structure across these zones, exploring assembly functional predictions. Results showed that compared control, experienced reduced water content, organic matter, available phosphorus, alkaline nitrogen, with lowest levels observed at 1 year. These values began rise after year, suggesting natural recovery stabilized. Microbial communities were closely related nitrogen. At mark, property changes significantly diversity, which then recover 2 years. The during was simpler, 102 nodes, 179 edges, an average degree 3.51, indicating early unstable, still adapting. By interactions had begun stabilize. Stochastic processes played key role in variability short-term subsidence.

In the context of bioelectrochemical systems (BES), a profound understanding taxonomic composition within indigenous microbial communities is crucial. Their metabolic versatility assumes foundational role in dictating functionality BES, yielding diverse applications for bioenergy production and bioremediation anthropogenically impacted estuaries. Employing high-throughput sequencing V3-V4 region 16S rRNA predictive metagenomic analyses three different estuaries samples (eutrophicated urban reservoir, mud volcano river, its river mouth), this study delves into intricate interplay between these their functions response to human-induced perturbations, with specific focus on applicability BES. Our findings illuminate remarkable distinctions among samples, manifesting variations functional pathways respective ecosystems. The volcano-affected characterized by highest diversity, exhibited most array processes, prominently dominated chemoheterotrophy (67.43%). contrast, mouth displayed distinct penchant autotrophy (33.33%). eutrophicated reservoir showcased balanced coexistence (41.18%) (35.29%). Regarding potential BES application, metabolism were associated anodic activity, while cathodic activity was restricted relatives. results suggested that potentially used reactions as electrogens generate bioelectricity reduce pollutants.
