ABSTRACT:
A process of degrading chloro-organics contained in liquid waste or effluent utilizes a white-rot fungus as the active ingredient in the chloro-organic degradation. The white-rot fungus is grown in the presence of certain nutrients including nutrient nitrogen and is then caused to enter a secondary metabolic state through nitrogen starvation. The fungus is then immersed in the liquid containing chloro-organics for a time period sufficient for the fungus to degrade the chloro-organics. At least periodically during the degradation period, the fungus is exposed to an oxygen enriched atmosphere. The efficacy and active lifetime of the fungus may be increased by the addition to the liquid of at least one member of the class consisting of nitrogen, a mixture of nutrient minerals, and a biological detergent.
