A bacterial strain A1-3 with iprodione-degrading capabilities was isolated from the soil for vegetable growing under greenhouses at Lhasa, Tibet. Based on phenotypic, phylogenetic, and genotypic data, strain A1-3 was considered to represent a novel species of genus Azospirillum. It was able to use iprodione as the sole source of carbon and energy for growth, 27.96 mg/L (50.80%) iprodione was reduced within 108 h at 25°C. During the degradation of iprodione by Azospirillum sp. A1-3, iprodione was firstly degraded to N-(3,5-dichlorophenyl)-2,4-d...
