Published: Jan. 11, 2024

Polycyclic aromatic hydrocarbons (PAHs) are pervasive organic pollutants in coastal ecosystems, especially tidal flat wetlands. However, the mechanisms through which PAHs impact soil bacterial communities of wetlands featuring a simple vegetation structure Yellow River Delta (China) remain largely unclear. In this study, we examined samples from two sites single type (Suaeda salsa) Delta. Specifically, investigated impacts on diversity and composition bacteria high-throughput 16 S rRNA sequencing. significantly increased carbon content but decreased total phosphorus (p = 0.02). PAH contamination notably reduced community α (Shannon index) β diversity. Furthermore, altered relative abundance phyla, classes, genera < 0.05). phyla Acidobacteriota Gemmatimonadota 0.05), while decreasing Bacteroidota, Desulfobacterota, Firmicutes compared to control wetland Moreover, certain properties [total nitrogen (TN), (SOC), (TP), salt (TS)] were identified as key parameters affecting bacteria, with specific being both negatively positively affected by PAHs, SOC, TN. summary, our findings could facilitate identification existing environmental problems offer insights for improving protection management ecosystems China.

Soil bacterial and fungal communities play key roles in the degradation of organic contaminants, their structure function are regulated by bottom-up top-down factors. Microbial ecological effects polycyclic aromatic hydrocarbons (PAHs) trophic interactions among protozoa bacteria/fungi PAH-polluted soils have yet to be determined. We investigated microbiome PAH-contaminated wasteland farmland soils. The results indicated that total concentration 16 PAHs (∑PAHs) was significantly correlated with Shannon index, NMDS1 relative abundances bacteria, fungi (e.g., Pseudofungi) microbiome.

Unraveling the shift in bacterial communities profile grown in sediments co-contaminated with chlorolignin waste of pulp-paper mill by metagenomics approach

Frontiers in Microbiology, Journal Year: 2024, Volume and Issue: 15

Published: March 11, 2024

Pulp-paper mills (PPMs) are known for consistently generating a wide variety of pollutants, that often unidentified and highly resistant to environmental degradation. The current study aims investigate the changes in indigenous bacterial communities profile grown sediment co-contaminated with organic inorganic pollutants discharged from PPMs. two samples, designated PPS-1 PPS-2, were collected different sites. Physico-chemical characterization PPS-2 revealed presence heavy metals (mg kg −1 ) like Cu (0.009–0.01), Ni (0.005–0.002), Mn (0.078–0.056), Cr (0.015–0.009), Pb (0.008–0.006), Zn (0.225–0.086), Fe (2.124–0.764), Al (3.477–22.277), Ti (99.792–45.012) along high content chlorophenol, lignin. comparative analysis samples using gas chromatography–mass spectrometry (GC–MS) major refractory compounds, such as stigmasterol, β-sitosterol, hexadecanoic acid, octadecanoic acid; 2,4-di-tert-butylphenol; heptacosane; dimethyl phthalate; hexachlorobenzene; 1-decanol,2-hexyl; furane 2,5-dimethyl, etc which reported potential toxic compounds. Simultaneously, high-throughput sequencing targeting V3–V4 hypervariable region 16S rRNA genes, resulted identification 1,249 1,345 operational taxonomic units (OTUs) derived total 115,665 119,386 sequences read, respectively.

ABSTRACT The Zoige uranium mine is situated in the harsh, cold northern region of Sichuan, characterized by its high altitude and fragile ecosystem. Uncovering organisms that thrive such extreme climates, particularly microorganisms, paramount importance for advancing bioremediation efforts. Herein, potential functional microbiota sequestration soil was explored using high-throughput sequencing combined with bioinformatics analysis. Analysis physicochemical properties soils showed concentration ranged from 35.20 to 40.62 µg·g −1 around mine. Bacterial communities differed significantly mine, most abundant phyla being Actinobacteria, Proteobacteria, Acidobacteria, Chloroflexi, Gemmatimonadota, Verrucomicrobia, Firmicutes. Notably, Actinobacteria considered a biomarker distinguishing linear discriminant analysis effect size. Meanwhile, correlation demonstrated Firmicutes Cyanobacteria were positively associated samples, coefficients 0.8601 0.7832, respectively. Furthermore, phylogenetic investigation reconstruction unobserved states revealed bacterial mainly enriched biosynthesis function these soils. Interestingly, abundance genes involved amino acid increased whereas related fatty decreased an increase content. Taken together, Firmicutes, via pathways soil. These findings are conducive obtaining strains developing microbial remediation technologies contamination.
