Abstract
Biodegradation of the styrene trimer was investigated, and its degrading bacteria were screened and isolated. Complex bacteria ST (strain ST1 and ST2) was isolated from contaminated soil by polystyrene and named by strain ST1 and ST2. ST1 and ST2 were identified by 16S rDNA and classified byOchrobactrum intermediumsp. andPseudomonas aeruginosasp., respectively. Biodegradation experiments were performed in batch and styrene trimer was used as a sole carbon source. Isolated two bacteria were used as degrading microorganisms. Initial liquid phase concentration of the styrene trimer was 50 mg/L. 95% of the styrene trimer was degraded in 17 days by the complex strain ST. The concentration was analyzed by using GC. Metabolites of bacteria were analyzed and three kinds of products that were identified by GC/MS.
