AB  - Microbially Enhanced Oil Recovery (MEOR) can enhance oil production with less 
      energy input and less costs than other technologies. The present study used 
      different aqueous electron donors (acetate, glucose, molasses) and an aqueous 
      electron acceptor (nitrate) to stimulate growth of heterotrophic nitrate reducing 
      bacteria (hNRB) to improve production of oil. Initial flooding of columns 
      containing heavy oil (viscosity of 3400cP at 20 degrees C) with CSBK (Coleville synthetic 
      brine medium) produced 0.5 pore volume (PV) of oil. Bioreactors were then 
      inoculated with hNRB with 5.8g/L of molasses and 0, 10, 20, 40, 60 or 80mM 
      nitrate, as well as with 17mM glucose or 57mM acetate and 80mM nitrate. During 
      incubations no oil was produced in the bioreactors that received 5.8g/L of 
      molasses and 0, 10, 20, 40 or 60mM nitrate. However, the bioreactors injected 
      with 5.8g/L of molasses, 17mM glucose or 57mM acetate and 80mM nitrate produced 
      13.9, 11.3+/-3.1 and 17.8+/-6.6% of residual oil, respectively. The significant 
      production of oil from these bioreactors may be caused by N(2)-CO(2) gas 
      production. Following continued injection with CSBK without nitrate, subsequent 
      elution of significant residual oil (5-30%) was observed. These results also 
      indicate possible involvement of fermentation products (organic acids, alcohols) 
      to enhance heavy oil recovery.
