Field study reveals distinct bacterial community shifts and altered metabolic pathways in heavy metal-contaminated paddy soils, indicating functional adaptation via microbial species replacement.

Key Points

To investigate soil bacterial community structures and functional profiles across heavy metal-polluted paddy fields near a smelter and identify key drivers of microbial community shifts.
Sampled paddy soils across three distinct sites located near a nonferrous smelter and a distant reference site in South Korea.
Characterized bacterial community composition, diversity, richness, and general soil properties alongside concentrations of arsenic, lead, and cadmium.
Predicted microbial functional profiles to evaluate enzymatic pathways associated with heavy metal exposure.
Soil bacterial community richness and diversity showed no significant differences among study sites, but distinct phylotypes and significant taxonomic abundance shifts occurred at phylum and genus levels.
Arsenic and lead concentrations significantly influenced community variations at finer taxonomic levels; Bacillus correlated positively with arsenic and cadmium, whereas Desulfatibacillum and Desulfovirga correlated negatively with arsenic, lead, and cadmium.
Contaminated soils exhibited functional enrichment in DNA replication, repair, translation, and nucleotide metabolism, alongside decreases in amino acid metabolism, lipid metabolism, and xenobiotic biodegradation.
