Isolation and characterization of a bacterium able to degrade high concentration of iprodione

A bacterial strain CQH-1 capable of mineralizing iprodione was isolated and characterized. In combination with morphological, physiological biochemical characters, and the phylogenetic analysis of 16S rRNA gene sequence, strain CQH-1 was identified as Microbacterium sp.. It could use iprodione and 3,5-dichloroaniline as the sole carbon source and energy source for growth. It completely degraded 100 mg L-1 of iprodione within 96 h at 30 째C. During the degradation of iprodione by strain CQH-1, two compounds were detected in GC-MS analysis and recognized as N-(3,5-dichlorophenyl)-2,4-dioxoimidazolidine and 3,5-dichloroaniline, respectively. So, the biodegradation pathway of iprodione by strain CQH-1 was proposed. This is the first report of iprodione-mineralizing strain from the genus of Microbacterium, and strain CQH-1 might be a promising candidate for its application in the bioremediation of iprodione-contaminated environments.The accepted manuscript in pdf format is listed with the files at the bottom of this page.
