| Outline of Final Research Achievements |
During wood degradation, white-rot, brown-rot, and soft-rot fungi produce glycoprotein that catalyzes a redox reaction between oxygen and electron donors to produce hydroxyl radicals, reduces Fe(III) to Fe(II), and strongly binds Fe(II). The continuous generation of hydroxyl radicals requires a constant supply of oxygen and an electron donor for the reduction of oxidized form of the glycoprotein to the reduced form. The extracellular pyridine coenzymes were detected in cultures of white-, brown-, and soft-rot fungi. Thus, these pyridine coenzymes could serve as electron donors for the production of hydroxyl radicals during wood degradation. Moreover, the culture method for brown-rot fungi was examined by determining ethylene generation which indicates one-electron oxidation activity.
