摘要：

An aerobic diethyl phthalate (DEP) degrading bacterium, DEP-ADI, was isolated from activated sludge. Based on its 16S rDNA sequence, this isolate was identified belonging to Sphingomonas genus with 99% similarity to Sphingomonas sp. strain C28242 and 98% similarity to S. capsulate. The specific degradation rate of DEP was concentration dependent with a maximum of 14 mg-DEP/(L h). Results of degradation tests showed that DEP-ADI could also degrade monoethyl phthalate (MEP), dimethyl phthalate (DMP), dibutyl phthalate (DBP), and diethylhexyl phthalate (DEHP), but not phthalate and benzoate.
