Abstract
A bioremediation method for degrading aromatic compounds using white-rot fungus and a sugar beet pulp substrate having a high nitrogen content is disclosed. The sugar beet pulp substrate has a total nitrogen content based on dry weight of about ten percent. Further the white rot fungus utilized can be taken from several genera, including Phanerochaete, Phlebia, Trametes, Pleurotus and Bjerkandera. Two specific genus species of the white rot fungi useful in the biormeditation method are Phaneorochaete chrysosporium and Bjerkandera adjusta. The admixture of a white rot fungus and sugar beet pulp solid substrate is capable of enzymatically degrading aromatic compounds. In addition the method is useful for degrading chlorinated aromatic compounds and polynuclear aromatic hydrocarbons in soil and water.
