摘要：

Immobilization technology is a method for restoring the ecological environment of oil-polluted areas. In this paper, the performance and degradation characteristics of immobilized microorganisms on different carriers were systematically studied starting with the selection of immobilized carriers. The results showed that cinnamon shell was the best carrier for screened Pseudomonas YT-11 to prepare immobilized microorganisms (diesel degradation rate was 69.57% in 5days). On the basis of the determination of diesel degradability and SEM structure, the degradation mechanism of immobilized microspheres was concluded: diesel was adsorbed on the surface of microspheres and then entered the interior to be degraded by microorganisms.
