Microbial mediation in the enrichment of geogenic phosphorus (P) is often mentioned but rarely explored, especially P processes through mineralization dissolved organic matter (DOM) containing natural P. To bridge theoretical gap, this study investigated mechanisms microbially mediated P-containing DOM by adopting an approach combining comprehensive field investigation with hydrochemical and molecular biological analyses. The co-analysis dominant microbial community compositions genomics revealed that metabolism pathways involved biodegradation were associated level inorganic (DIP). Specifically, dephosphorylation was more pronounced under conditions limited DIP, while C-P bond cleavage primary metabolic pathway sufficient DIP. Co-occurrence network analysis further indicated substrates for DIP differed between cleavage, namely CHONSP1 compounds region highly unsaturated-low O (AI ≤ 0.5, H/C < 1.5, O/C 0.4) CHOP1 unsaturated-high ≥ 0.4), respectively. These findings provide new insights into groundwater from perspective have potential implications bioremediation P-contaminated at different contamination levels.
