A IAS degradation strain with high resistance,which could taking linear alkylbenzene sulphonate(IAS) as only carton origin for growth,was isolated from the drain canal of Hangao Washing Plant of Xuzhou.Results showed that the optimum conditions of this strain growth for degradation of LAS were 30 ℃,pH 6.0,oxygen supply 150 ml/500 ml triangle vase,120 r/min,LAS concentration of 200~600 mg/L.The cell growth amount was up to 0.443(OD_460) and the degrading rate up to 89.4%.The ability of the strain to degrade ...
