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

The most effective strain for the degradation of toluene, i.e., JYZ0315 was screened by the further mutation of the above strains. The degradation capacity experiment was carried out in simulated groundwater. Under the optimal conditions, the degradation rate could reach 93.5%. During the extend application experiments with a percolation tank, the degradation of toluene reached 87.3% in 11 d and 95.2% in 15 d, which was close to that of the microenvironment, and this proves that JYZ0315 is one of the predominant strains to degrade toluene in groundwater.展开更多
