Contribution of microbial metabolism to geogenic phosphorus enrichment in groundwater

Microbial mediation in the enrichment of geogenic phosphorus (P) is often mentioned but rarely explored, especially in P enrichment processes through the mineralization of dissolved organic matter (DOM) containing natural P. To bridge the theoretical gap, this study investigated the mechanisms of P enrichment through microbially mediated mineralization of natural P-containing DOM by adopting an approach combining comprehensive field investigation with hydrochemical and molecular biological analyses.

地质源磷（P）富集过程中的微生物介导作用虽常被提及却鲜有探索，尤其是针对通过含天然磷的溶解有机质（dissolved organic matter, DOM）矿化作用实现的磷富集过程。为填补该领域的理论空白，本研究采用全面野外调查与水化学、分子生物学分析相结合的研究手段，针对含天然磷的溶解有机质经微生物介导矿化过程驱动的磷富集机制展开了系统探究。
