Abstract

The degradation kinetics of co-metabolic biodegradation of two linear alkylbenzene sulfonate (LAS) strains was researched. Two bacterial strains which could degrade linear alkylbenzene sulfonate by co-metabolism mechanism, named as L-2 and L-15 were determined to Klebsiella sp.and Enterobacter sp.The optimal degradation conditions of L-2 and L-15 were investigated by the orthogonal experiment.The results suggested that the degradation rate of LAS (50mg/L) by L-2 was up to 94.2% when glucose was chosen as growth substrate under the conditions as : 30 , pH 7.5, glucose concentration 500mg/L,while the degradation rate of LAS (50mg/L) by L-15 was up to 92.2% under the conditions as: 30 , pH 7.5, glucose concentration 1000mg/L.The degradation reactions were consistent with characteristics of first-order kinetics when the concentration of LAS ranged from 25mg/L to 100mg/L. Certain theoretical basis of the treatment of LAS wastewater was provided by this study.
