Simulation of Heat Generated on Crude Oil Degradation upon the Effect of Temperature in Bacteria Growth Kinetics in a Bioreactor

Ukpaka C. P., Okirie F. U.


Model was established to simulate the heat generated by bacteria with the interaction of substrate (crude oil) degradation in a bioreactor upon the influence of temperature. The model was predicted by simulating the characteristics of bacteria interaction with substrate at temperature of 15oC, 30oC, 45oC, 60oC, 75oC, 90oC, 105oC and 120oC and heat generated is within the range of -1.0 to 7.1kcal/hr for bacteria in fresh water medium whereas for bacteria in salt water medium reveals – - 1.0 to 12.2kcal/hr.
However, in terms of heat generated by the substrate reveals – 5.0 to 7.5kcal/hr for substrate degradation in salt water medium whereas for fresh water medium reveals – 4.0 to 24.2kcal/hr for substrate degradation in fresh water medium. The phenomena of temperature effect was monitored with respect to inhibition and activation of the bio-reaction process and the effectiveness of the substrate degradation was governed by the role played by temperature. Research demonstrates thermal degradation at elevated temperature of thermophilic(< 45oC) and super thermophilic (< 75oC) and at stage mesophilic bacteria was totally inhibited whereas temperature less than 45oCfacilitated the bacteria growth thereby acting as activator in the bioreactor.
