- Abstract
A bacterial strain CQH-1 capable of mineralizing iprodione was isolated and characterized. On the basis of its morphological, physiological, and biochemical characteristics combined with phylogenetic analysis of its 16S rRNA gene sequence, strain CQH-1 was identified as a Microbacterium sp. CQH-1. It was able to use iprodione and 3,5-dichloroaniline as the sole source of carbon and energy for its growth. It completely degraded 100 mg·L−1 iprodione within 96 h at 30 °C. During the degradation of iprodione by strain CQH-1, 2 compounds were detected in GC-MS analysis and were recognized as N-(3,5-dichlorophenyl)-2,4-dioxoimidazolidine and 3,5-dichloroaniline. So, the biodegradation pathway of iprodione by strain CQH-1 was proposed. This is the first report of an iprodione-mineralizing strain from the genus Microbacterium, and strain CQH-1 might be a promising candidate for application in the bioremediation of iprodione-contaminated environments.
