| Abstract: | The microbial degradative characteristics of DinButy1 Phthalate (DBP) was investigated by a strain FS1 that was isolated from the activated sludge at a petrochemical factory. The optimum pH and temperature of the strain FS1 for degrading of DBP are 6580 and 2035, respectively. The degradation of Dinbutyl phthalate can be described by the firstorder reaction model. The experimental results demonstrated that the strain FS1 has strong ability of degrading DBP. |
