Successful design and operation of a bioremediation process for soil contaminated with crude petroleum requires an in-depth understanding of the type of microorganisms involved, the specific reaction they perform, the factors that affect their performance, and their bioremediation kinetics. This paper attempts to develop the kinetic model for the pH being one of the major environmental factors that influence the bioavailability of contaminants, the availability of other nutrients, the activity of biological processes and hence the overall bioremediation kinetics of crude-petroleum contaminated soil. The pH model have been developed at the chemical and mathematical level with the basic assumptions that i) all side chains necessary for catalysis are in the correct protonation state; ii) an enzyme can exist in three degrees of protonation; iii) only one form of the enzyme is capable of binding substrate and catalyzing the reaction; and iv) the substrate is in great enough excess such that the equilibrium constant for the protonation of the free enzyme is the same as for the enzyme-substrate complex. The resulting model equations enable to obtain values of the equilibrium constants (K1 and K2) which are significant in determination of the optimal pH for bioremediation reaction rate.
