Outline of Final Research Achievements

Wood decay leads to a significant increase of the risk of collapse in wood structures such as wood houses and exterior wood constructions, and a reduction in commercial value of the material itself by discoloration and staining. Microbial volatile organic compounds (MVOCs) could be used to nondestructively detect hidden wood decay fungi in dwellings. In this study, MVOCs emitted from wood decay fungi were analyzed by three methods (GC/MS with a thermal desorption system, PTR/MS, and HS/SPME/GC/MS), and it was clarified that the characteristics of each analytical methods. The relationships between the stages of wood-decay and MVOCs produced by wood rotting fungi were also obtained. MVOCs can be used as a tracer for the presence of wood-decay fungi for early detection of wood decay.
