Abstract:
A method of degrading compounds contained in a liquid or solid waste stream, comprising the steps of:a) providing in any order i) a reaction containing means having a semi-permeable membrane partition and first and second sides of said partition, ii) a manganese peroxidase derived from a white rot fungus, for which said membrane is not permeable, and iii) at least one substrate for said peroxidase;b) adding in any order, under conditions suitable and for a time sufficient to produce a reaction intermediate that is capable of degrading compounds in said waste stream, i) to said first side of said partition, said peroxidase and said substrate to create a reaction mixture, thereby generating a reaction intermediate for which said membrane is permeable, ii) to said second side of said partition, said compound-containing waste stream; andc) applying a pressure to said reaction mixture on said first side of said partition so as to force said reaction intermediate across said membrane into said compound-containing waste stream, under conditions suitable and for a time sufficient to degrade said compounds by the action of said intermediate upon said compounds, thereby degrading said compounds.
