Marinobacter vinifirmus was shown to degrade toluene as sole carbon and energy source under aerobiosis and at NaCl concentrations in the range 30-150 g/L. Maximum toluene consumption rate, total CO2, and biomass productions were measured in the presence of 60 g/L of NaCl. Under these conditions, 90% of the carbon from toluene was recovered as CO2 and biomass. Maximum specific toluene consumption rate was about 0.12 mgC toluene mgC biomass(-1) h(-1) at NaCl concentrations between 30 and 60 g/L. It decreased to 0.03 mgC toluene mgC biomass(-1) h(-1) at 150 g/L. Besides toluene, M. vinifirmus degraded benzene, ethylbenzene, and p-xylene. Benzene and toluene were utilized to a lesser extent by another Marinobacter sp., Marinobacter hydrocarbonoclasticus.
