The integrity of Eadic-Hofstee concept was tested for the determination of the functional coefficients and parameters of crude oil degradation kinetics. The techniques enhanced the relationship between the substrate divided by the specific rate of the substrate degradation against substrate concentration (TPH). The investigation reveals the values of the biokinetic parameters of maximum specific rate of substrate degradation (Vmax) and the equilibrium constant values of the substrate degradation (Ks). The concept of Eadic-Hofstee model was obtained from the reaction rate expression of Michaelis Menten model, which was further expressed in term of LineWeaver Burk Plot and rearrangement resulted in the Eadic-Hofstee model development. Biokinekic parameters determined are within the range of 0.0172 to 204.08 (ppm/day)-1 for Vmax and -1594.89 to -1750 (ppm)-1 for Ks obtained from Michaelis Menten model and for Eadic-Hofstee the biokinetic parameters are within the range of 5.64525E-05 to 0.00055 (ppmm/day)-1 for Vmax as well as 0.0112865.53 to 0.35 (ppm)-1for Ks all parameters demonstrating the characteristics of the sun-dried performances. However, the room-dried revealed the following values of the biokinetic parameters as Vmax is 454.55 to 833.33 (ppm/day)-1 and Ks is -8447.27 to -20.75, which was obtained from Michaelis Menten model and Vmax is 9.32923E-05 to 0.046 (ppm/day)-1 and Ks is 0.032707342 to 40.19 (ppm)-1 for Eadic-Hofstee Plot model. The application of the model is found useful in evaluation of the biokinetic parameters and coefficients of crude oil degradation.
