Abstract

The main objective of this study was to isolate and identify the aerobic bacteria in bacterial community of constructed wetland in Vietnam, which were spiked with benzene. For this target, four random samples of rhizosphere soil of phragmiteskarkas from constructed wetlands in Vietnam were collected and mixed together. The soil sample was labeled VS. Bacteria in the sample was grown in 80 mg/L benzene liquid media with optimal conditions of temperature and shaken to find out whether bacteria in the sample can remove benzene or not. The result showed that bacteria in the sample can survive and treat benzene well. Strains of bacteria were isolated through incubation in Burk’s medium mixed with benzene. The strain named VS1 from VS sample was obtained. The strain adapted well in agar medium containing benzene as sole carbon source. Through molecular methods, VS1 was identified as PandoraeapnomenusaCM25.
