Summary Degradation of the fungicide iprodione by the Paenarthrobacter sp. strain YJN‐5 is initiated via hydrolysis of its N1 amide bond to form N ‐(3,5‐dichlorophenyl)‐2,4‐dioxoimidazolidine. In this study, another iprodione‐degrading strain, Paenarthrobacter sp. YJN‐D, which harbours the same metabolic pathway as strain YJN‐5 was isolated and characterized. The genes that encode the conserved iprodione catabolic pathway were...
