Abstract: The present disclosure discloses a novel strain of Glutamicibacter, derived from insects, which efficiently degrades bifenthrin, belonging to the field of microbial strains. The Glutamicibacter CCTCC NO: M20221445 of the present disclosure was isolated from the intestinal tract of bifenthrin-resistant Ectropis grisescens Warren larvae. It exhibits unique genomic characteristics, growth and phenotypic traits, physiological and biochemical characteristics, as well as the ability to utilize and degrade bifenthrin efficiently. Specifically, it can effectively degrade bifenthrin. Based on phenotypic features, physiological and biochemical characteristics, chemical composition, and molecular biology-based polyphasic classification, Glutamicibacter CCTCC NO: M20221445 is identified as a new species. This bacterium possesses the capability to efficiently degrade bifenthrin, laying the foundation for biological control of E. grisecens and offering new microbial resources to address pesticide residue problems.
