In order to enhance the degradation of Di-n-octyl phthalate (DOP). One bacterial strain was isolated from activated sludge of waste water treatment plant(WWTP) using Di-n-octyl phthalate (DOP) as the sole source of carbon and energy. According to the phylogeny of 16S rDNA sequence, the bacterial strain ESF-17 was identified as Phenylobacterium sp. Biodegradation of DOP by Phenylobacterium ESF-17 was investigated. Results showed that the optimum pH and temperature for DOP degradation by Phenylobacterium ESF-17 were 8.0 and 25°C. The strain exhibited higher degradation efficiencies and growth rates in alkalinity than in acidity. The strain could degrade approximately 93% of 400mg/L DOP shorter alkyl chain PAEs, whereas the degradation efficiency of longer alkyl chain PAEs were relatively poor. The results suggest that Phenylobacterium ESF-17 may represent a promising application for DOP bioremediation.
