The bioremediation process can be evaluated by the change caused by the bacterial activity of degrading or immobilization of contaminants.
Chemical Changes
The process of bioremediation effects ground water chemistry. Physiological principles of the exposed microorganisms suggest the chemical changes to the contaminants. The reactions involves microbial activity have well defined reactants and products. They are also specific in term of oxygen, acceptors and contaminants.
The chemical reactants and products are specific to the reactions that the microbes catalyze can be determined from the chemical equations for the reactions. Consider the following chemical equation that shows degradation of toluene (C7H8)
