Whole-Genome Sequencing of a Chlorimuron-Ethyl-Degrading Strain: Chenggangzhangella methanolivorans CHL1 and Its Degrading Enzymes.

ABSTRACT: Chlorimuron-ethyl is a commonly used sulfonylurea herbicide, and its long-term residues cause serious environmental problems. Biodegradation of chlorimuron-ethyl is effective and feasible, and many degrading strains have been obtained, but still, the genes and enzymes involved in this degradation are often unclear. In this study, whole-genome sequencing was performed on chlorimuron-ethyl-degrading strain, Chenggangzhangella methanolivorans CHL1. The complete genome of strain CHL1 contains one circular chromosome of 5,542,510 bp and a G+C content of 68.17 mol%. Three genes, sulE, pnbA, and gst, were predicted to be involved in the degradation of chlorimuron-ethyl, and this was confirmed by gene knockout and gene complementation experiments. The three genes were cloned a
