摘要

The effects of plant hormones for biodegradation of polycyclic aromatic sulfur heterocycles (PASHs) and diesel fuel were studied. Indole butyric acid (IBA) and gibberellin were found to promote biodegradation of DBT and diesel, respectively. Concentrations of plant hormones, pH, temperature, soil moisture and substrate concentrations were optimized in microbial metabolic processes. Two main factors including temperature and IBA concentration were determined by factor analysis in DBT biodegradation. And soil moisture and diesel concentration were important factors in diesel biodegradation. Binding sites between cell surface and DBT or diesel components were performed by molecular operating environment (MOE). This study suggested that plant hormones could be applied to effectively remove pollutants in environment.
