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.
已证明 Marineobacter vinifirmus 可以在有氧条件下并在 30-150 g/L 的 NaCl 浓度范围内将甲苯作为唯一的碳源和能源进行降解。在存在 60 g/L NaCl 的情况下,测量了最大甲苯消耗率、总 CO2 和生物量产量。在这些条件下,甲苯中的 90%的碳被回收为 CO2 和生物量。在 30-60 g/L 的 NaCl 浓度下,最大比甲苯消耗率约为 0.12 mgC 甲苯 mgC 生物质(-1) h(-1)。在 150 g/L 时,其下降至 0.03 mgC 甲苯 mgC 生物质(-1) h(-1)。除了甲苯,M. vinifirmus 还降解了苯、乙苯和对二甲苯。另一种 Marinobacter sp.,Marinobacter hydrocarbonoclasticus 对苯和甲苯的利用程度较低。
