Microorganisms capable of degrading di-n-butyl phthalate (DBP) were immobilized by polyvinyl alcohol (PVA) and used for DBP degradation. The characteristics of DBP degradation by immobilized and free cells were investigated. The experimental results showed that the degradation rate of immobilized cells was higher than that of free cells. The optimal pH and temperature for DBP degradation were determined...
The microbial degradation by acclimated activated sludge of three phthalates, priority pollutants listed by both the China National Environmental Monitoring Centre and the U.S. EPA, i.e., dimethyl (DMP), di-n-butyl (DBP), and di-n-octyl (DOP) phthalate was investigated. The experimental results demonstrated that DMP and DBP with the shorter alkyl-side chain phthalic acid esters (PAEs) can be rapidly...
