Bioremediation of chlorimuron-ethyl-contaminated soil by Hansschlegelia sp. strain CHL1 and the changes of indigenous microbial population and N-cycling function genes during the bioremediation process.

Highlights: [•] Strain CHL1 was isolated and used to soil bioremediation. [•] Chlorimuron-ethyl had low residue in soils by inoculation strain CHL1. [•] Inoculation twice had higher remediation efficiency and longer survival time. [•] Microbial populations recovered to CK level by bioremediation. [•] The abundances of N-cycling functional genes were partially restored. [ABSTRACT FROM AUTHOR]
