  • Aqueous-soluble polymeric coal substrate for depolymerization by a lignin peroxidase
    Patent number: 5036013
    Abstract: A method is provided for converting coal to low molecular weight organic compounds comprising combining an aqueous solution of an aqueous-soluble polymeric coal substrate with a lignin peroxidase, oxygen and hydrogen peroxide. The invention is exemplified using the lignin peroxidase from Phanerochaete chrysosporium. Also provided are aqueous-soluble polymeric coal substrates suitable for lignin peroxidase-catalyzed depolymerization and methods of preparing such substrates. Finally, a method is provided for isolating the lignin peroxidase from mycelia-free, unconcentrated media of cultures of P. chrysosporium producing the enzyme.
