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 °C. During the degradation of iprodione by strain CQH-1,

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.
