| Abstract: | Degradation of pyrene and benzoa]pyrene in soils by Bacillus subtilis,white rot fungus and mixed degrading bacteria that were isolated from oil contaminated soil were investigated.Effects of Tween80 and glucose on biodegradation of PAHs were also preliminarily discussed.Results showed that the residual rate for pyrene was 7.58%±0.59% and 8.69%±1.35% on the 60th day when degraded by Bacillus subtilis and the isolated bacteria respectively,while it was 48.18%±0.56% for the uninoculated control soil.Benzoa] pyrene also showed residual rate with 66.27%±3.03%,62.28%±2.54% and 67.67%±2.98% on the 60th day in remediation soils by Bacillus subtilis,white rot fungus and the isolated degrading bacteria respectively.And in the control soil,70.25%±1.62% of the initial benzoa]pyrene was left after 60d.After adding Tween80,the residual rate of pyrene by Bacillus subtilis decreased by 2.41%.As for benzoa]pyrene,the residual rate decreased by 12.72% for Bacillus subtilis and 14.59% for white rot fungus.Results showed that the residual rate of pyrene by Bacillus subtilis decreased by 2.30% after adding glucose,while it decreased by 5.39% and 11.93% for benzoa]pyrene degraded by Bacillus subtilis and white rot fungus respectively. |
