SynCom-mediated herbicide degradation activates microbial carbon metabolism in soils.

ABSTRACT: Extensive herbicide residues in the black soil of northeastern China are considered a significant agricultural pollution threat, yet effective bioremediation of this complex and persistent mixture remains a challenge. We identified 16 bacterial species that associated with these herbicide residues in situ, nine of which were culturable and could degrade multiple herbicides. From these strains, we constructed a four-member synthetic microbial community (SynCom) that degrades multiple herbicides, stabilizes colonization, increases soil bacterial biodiversity, and alters soil enzyme activity. Under laboratory conditions, the SynCom degraded eight herbicides within 48 h with >60% efficiency, and accumulated carbon on the cell surface of the constituent species. In black soil microcosm trials,
