光合细菌PSB07-15对水培黄瓜体系中甲氰菊酯污染的生物修复

为了探索光合细菌PSB07-15降解甲氰菊酯的应用潜力,在实验室研究了光合细菌PSB07-15对水培黄瓜体系中的甲氰菊酯污染的生物修复效率.结果表明,培养30 d,光合细菌PSB07-15对黄瓜营养液中100 mg·L~(-1)甲氰菊酯降解率达到47.63%,黄瓜中甲氰菊酯降解率达59.73%.光合细菌PSB07-15可以使黄瓜的根长和生物量显著增加,而黄瓜的根活力以及根H_2O_2酶活力增加并不显著.

Bioremediation of Fenpropathrin by Photosynthetic Bacterial Strain PSB07-15 in Hydroponic System for Cucumber Culture

The bioremediation efficiency of fenpropathirn by photosynthetic bacterial strain PSB07-15 in hydroponic cucumber system was e-valuated in lab, for actual potential application of bioremediation by photosynthetic bacterium. The results showed that the strain PSB07-15 could degrade fenpropathrin effectively in hydroponic system. Fenpropathrin was degraded up to 47.63% at the level of 100 mg·L~(-1) by the strain PSB07-15 in hydroponics nutrient solution and degraded up to 59.73% in cucumber at day 30. The strain PSB07-15 significantly en-hanced root-length increment and biomass increment but not the root activity value and root catalase activity value of cucumber. The results indicated this strain PSB07-15 may have an important role in bioremediation in agricultural practice.
