Abstract:
A bacterium which can effectively degrade LAS (Linear Sodium Alkylbenzenesulfonate) was isolated from washing powder manufacturing effluent and was preliminarily identified as Corynebacterium jeikeium GZ6. The bacterium can degrade LAS up to till 700 mg/L, and the optimum pH, temperature and concentration of LAS are 7.0, 30℃ and 400 mg/L, respectively. The biodegradation rate can reach 98.7% after 24 hours'cultivation in the suitable conditions. Experiments also showed that some heavy metal ions such as Hg2+ , Co2+ , Cd2+ can differently inhibit the degradation of LAS.
