Biodegradation of benzene by halophilic and halotolerant bacteria under aerobic conditions

Appl Environ Microbiol. 2004 Feb;70(2):1222-5. doi: 10.1128/AEM.70.2.1222-1225.2004.

Abstract

A highly enriched halophilic culture was established with benzene as the sole carbon source by using a brine soil obtained from an oil production facility in Oklahoma. The enrichment completely degraded benzene, toluene, ethylbenzene, and xylenes within 1 to 2 weeks. Also, [14C]benzene was converted to 14CO2, suggesting the culture's ability to mineralize benzene. Community structure analysis revealed that Marinobacter spp. were the dominant members of the enrichment.
