Research on gaseous COS degradation by brown-rot fungus Gloeophyllum trabeum
2024 - IRG/WP 24-11033
…We investigated the COS degradation and its metabolism in Gloeophyllum trabeum NBRC 6430, a model brown-rot fungus, and found that COS affects its growth and sulfur metabolites. Based on the results, we hypothesized that wood rotting fungi can use COS as one of sulfur sources when they colonize the wood in which…

A novel cellulose-binding domain from the brown-rot fungus Gloeophyllum trabeum
2023 - IRG/WP 23-11019
…this study, we found a novel CBD from the brown-rot fungus Gloeophyllum trabeum. The deduced amino acid sequence of this novel CBD (GtCBD) showed no homology to any known CBD. The three-dimensional structure model of GtCBD predicted from the amino acid sequence suggested the structure consisted of two α-helices,…

Solid state NMR study on pine wood degraded by brown rot fungus Gloeophyllum trabeum
1994 - IRG/WP 94-10067
Blocks of Pinus koraiensis wood were degraded by Gloeophyllum trabeum and examined by solid-state 13C NMR spectroscopy. Chemical compositions were estimated from relative signal aras. There was no evidence for preferential degradation of the noncrystalline cellulose which accounted for about 4% by weight of…
