Abstract

Abstract: In this study, introduced bacteria were applied in the bioremediation of pyrene and benzo(α)pyrene in organic pollutants-contaminated soils, aimed to test whether it was feasible to introduce bacteria to environmental engineering. Three introduced bacteria were immobilized separately or together to degrade the pyrene and benzo(α)pyrene in soil, taking dissociated bacteria as the control, and comparing with three indigenous bacteria. The results showed that immobilized introduced bacteria, either single or mixed, had higher degradation efficiency than dissociated bacteria. Compared with indigenous bacteria, some introduced bacteria had predominance to some degree. The introduced bacteria-mixture had better degradation efficiency after being immobilized. The degradation rate of pyrene and benzo(α)pyrene after treated with immobilized bacteria-(B61-B67)-mixture for 96 hours was 43.49% and 38.55%, respectively.
