Various nutrient media and reactor configurations were explored in order to grow the white rot fungus Phanerochaete chrysosporium, induce its active enzyme system, develop kinetic data for the degradation of 2-chlorophenol and use chemical engineering analysis to design an effective reactor. Preliminary experiments indicated that the biodegradation rate was improved by a factor of 40 when the fungus was immobilized. As a result, the project focused on a packed-bed reactor employing a silica-based porous support for the fungus, and a well-mixed reactor employing alginate beads as the immobilizing medium. Both were very effective in degrading 2-chlorophenol at inlet concentrations up to 520 ppm. Apparent Michaelis-Menten kinetic rate constants were developed for both reactors, which to our knowledge are the first reactor design parameters to be published for this fungus for treating a hazardous waste.
