To isolate a novel strain that could degrade many kinds PAEs efficiently and investigate the DBP-degrading pathway in this strain.Based on its 16S rRNA gene sequence, was identified as Rhizobium sp. This strain, named LMB-1, can also utilize phthalates, such DEHP, DMP, DBP DEP. During degradation of DBP, six possible metabolites, diethyl phthalate, mono-ethyl di-methyl mono-methyl phthalic acid tartaric acid, were by gas chromatography-mass spectrometry (GC-MS) analysis, study.In summary, sp., found to be capable degrading PAEs, it determined degraded DMP completely within 45 h. DEP, MEP, MMP, PA detected during course LMB-1. We propose or other PAEs. Our results offer potential candidate, for use bioremediation cultivated soil contaminated PAEs.This is first report concerning complete phthalate esters
