Isolation and Identification of Haloxyfop-R-methyl Degrading Bacteria
摘要
Abstract
According to the potential carryover of long residual pesticide's residual to rotational crops,takingHaloxyfop-R-methyl as a model pollutant, three bacterial strains were isolated by selective enrichment from soil exposed to long residual herbicides, then the cultural characteristics and biochemical features of the three strains were determined and identified as HM1 ,HM2 and HM3,HM1 and HM2 were identified as Bacillus sp. , while HM3 was identified as Methyloeoccus sp. Then the effect of sugar content, temperature, pH value and initial concentration of haloxyfop-R-methyl on the growth of the three strains were studied,it was found out that the optimal sugar content for HM1 and HM3 was 0％,and HM2 was 0.5％; the optimal temperature range for HM3 and HM1 was 20 ℃ to 37 ℃ ,and HM2 was 25 ℃ to 41 ℃; the optimal range of pH for HM3 was 6.0 to 9.0 ,that for HM1 and HM2 was 6.0 to 8.0; the optimal initial concentration of Haloxyfop-R-methyl for HM3 was 200 mg/L,that for HM1 and HM2 was 100 mg/L.关键词
