Bioremediation of Petroleum Contaminated Soil by Nano-meter Immobilized Microorganism

摘要：

Microbial strains of petroleum hydrocarbon degrading were screened and purified by collecting samples in petroleum contaminated soil. Highly efficient degrading strains H and F served as bioactive substances respectively, nanoporous silica was synthesized as a carrier by bio-macromolecule bionic technology, nanometer immobilized microorganisms were prepared by surface adsorption (surface binding) method. Its application in bioremediation showed that the primary degradation efficiency was as high as 96.2％ in 50h. By repeating experiments for 8 times, all of the degradation efficiency are more than 95％.
