The characteristic of its degradation was researched and the results showed that the optimum conditions of this strain for degrading LAS were 30℃, pH 6.0, 150 ml solution in 500 ml triangle vase, 120 r/min, LAS concentration of 200 - 600 mg/L. The growth amount of the bacteria were up to 0. 443 （ OD400 ） and the degrading rate was up to 89.4%. The ability of the bacterium to degrade LAS could be as high as concentration of 1 200 mg/L.展开更多
