DDT exposure drives time-dependent restructuring of soil microbiomes in urban garden microcosms

declined. Inferred functional profiling revealed a marked metabolic restructuring in which pathways involved in aromatic amino acid and fatty acid metabolism decreased, while modules related to the degradation of chlorinated aromatic compounds, redox homeostasis, and stress responses were enriched. These findings suggest that DDT induces a specialized successional trajectory in soil microbiome, reflecting an adaptive transition toward a stress-resilient and potentially degradative community.
