Soil microbial communities are particularly sensitive to selenium contamination, which has seriously affected the stability of soil ecological environment and function. In this study, we applied high-throughput 16S rRNA gene sequencing examine effects low high doses sodium selenite selenite-degrading bacterium, Rhodococcus qingshengii PM1, on bacterial community composition, diversity, assembly processes under controlled laboratory conditions. Our results indicated that strain PM1 were key predictors structure in selenium-contaminated soils. Exposure initially led reductions diversity a shift dominant groups, an increase Actinobacteria decrease Acidobacteria. Sodium significantly reduced simplified co-occurrence networks, whereas inoculation with partially reversed these by enhancing complexity. Ecological modeling, including normalized stochasticity ratio (NST) Sloan’s neutral model (NCM), suggested stochastic predominated stress. Null analysis further revealed heterogeneous selection drift primary drivers turnover, promoting species dispersal buffering against negative impacts selenium.

Using environmental DNA sequencing, we analyzed communities in soils 3 natural vegetation (NV) plots, traditional afforestation (TA) and 12 (SR) plots located Triangle Island Zhuhai city, China, during both summer winter seasons. We estimated metabolic function, nutritional type, life strategy Proteobacteria through FAPROTAX rrnDB databases. Our findings demonstrated that was predominant phylum (relative abundance = 40.1–48.4%) bacterial across all three treatments. The relative Alphaproteobacteria ranged from 28.5% 38.1%, which significantly greater (2.6–10.3 times, p < 0.05) than Betaproteobacteria or Gammaproteobacteria. Most (90%) genera rhizobial found NV TA were also present SR soil, but there distinct differences community structures between NV/TA soil.

Tannery effluent poses significant risks to soil health, primarily through contamination with heavy metals like chromium, sulphides, and persistent organic pollutants (POPs). These toxic substances inhibit microbial activity, reducing nutrient cycling matter decomposition essential for fertility. Beneficial microorganisms, including nitrogen-fixing bacteria, are particularly affected, leading altered communities dominated by less advantageous, metal-tolerant species. Accumulation of POPs disrupts enzymatic activities, interferes plant root growth, complicates remediation efforts due pollutant migration groundwater potential entry into the food chain. Prolonged exposure such contaminants diminishes fertility, reduces resilience, ecosystem services, posing threats agricultural productivity environmental health. This review was aimed outline what made bioremediation a superior treatment technology among other methods used in remediating tannery contaminated soil.
