Mechanistic aspects of the reactions of copper complexes with lignin in the presence of hydrogen peroxide and lipid hydroperoxide model compounds as proposed for white rot fungi
2001 - IRG/WP 01-10399
The structural principles and the oxidative reactions of the catalytic system consisting of copper, hydroperoxides, and copper coordination compounds that contain aromatic nitrogen atoms are similar to those of catalytic centers of oxidative enzymes involved in delignification reactions of white rot fungi. The system is capable of selectively degrading lignin and its low molecular weight would all...

Biological control of the sapstain fungus Diplodia pinea (syn. Sphaeropsis sapinea) in the field
2008 - IRG/WP 08-10663
Diplodia pinea, syn. Sphaeropsis sapinea, is well known as the worldwide ocurring causal agent of the Diplodia tip-blight disease on various pine species, leading to great losses of valuable wood in the forests. Moreover, this fungus is also responsible for the fornation of sapstain of felled logs, leading to undesired disation of surface layers in the OSB manufacturing industry. In Central Europe...

Cell wall properties of softwood deteriorated by fungi: combined chemical analyses, FT-IR spectroscopy, nanoindentation and micromechanical modelling
2013 - IRG/WP 13-20527
Mechanical properties of wood are determined by its inherent hierarchical microstructure, starting at the nanometer scale, where the elementary components cellulose, hemicelluloses, and lignin build up the wood cell wall material. Fungi cause degradation and decomposition of these components and, thus, alter the mechanical properties of wood. The aim of this study is to gain new insight into these...
