Abstract

In lieu of Abstract, excerpt from Conclusion of Voltammetric Study of Interaction of Copper and Model Fungal Secreted Ligands: In summary, the cyclic voltammetry study shows evidence that the chelatormediated Fenton reaction is favored in the wood cell wall, where it may promote the degradation process. Also, reaction mechanisms between Cu(II), 2,3-DHBA and H202 have been proposed which provide at least partial explanations for the H202 cycle, and the mechanism for non-enzymatic, chelator-mediated Fenton reactions in brown rot wood decay processes. Future research in this area should explore cyclic voltarnrnetry analyses of Cu(I1) and ligands secreted by fungi, such as 2,5-DMHQ or 2,5-DMBQ in the absence or presence of H202 under a range of acidic conditions. Cyclic voltammetry experiments should also be conducted with Fe(III), oxalic acid and ligands secreted by fungi, to gain insight into the mechanism and kinetics of the relevant redox reactions in wood decay processes.
