| Outline of Final Research Achievements |
Accurate and quantified analysis is needed to understand the biological degradation of wood biomass at a molecular level. In order to estimate quantitatively in the biomass sample containing complicated and various molecules, we have developed methodology to correct errors occurring in the 2D-HSQC NMR measurements. The variation in the signal integration value originating in the relaxation process of each molecule and differences of a spin couple state were . We also measured the dynamic change of extracellular metabolites and the structural change of a cell wall molecules in a wood decay.
