Outline of Final Research Achievements

Brown-rot fungi has been considered as microorganisms which are able to remove plant cell wall polysaccharides, such as cellulose and hemicelluloses, together with extensive modification of lignin structure, but without lignin metabolism. The wood degradation mechanism would be used for the development of new saccharification process which does not require the de-lignification process.
We focused that peptides and low-molecular proteins with iron-binding ability, which has been considered to be involved in wood degradation system by brown rot fungi. In the present study, we selected and analyzed the peptides and low-molecular proteins produced by brown rot fungus in order to identify the key factor which enable us to control the brown rot system.
