Outline of Final Research Achievements

The aim of this research was the production of materials having surfactant function from woody biomass (wood powder) focusing on Lignin Carbohydrate Complex (LCC). A variety of LCC fragment model compounds were chemically synthesized. These compounds were needed to optimize the process to separate LCC from wood powder without losing the unique chemical structure of LCC. Useful physicochemical information on LCC-specific chemical structures was collected from these compounds. By analyzing the fractions obtained from wood powder and comparing the information with synthesized model compounds, it was speculated that LCC likely existed in the wood powder.

Academic Significance and Societal Importance of the Research Achievements

本研究成果の学術的意義は、これまでは化学的にはセルロース、ヘミセルロース、リグニン、抽出成分というように、物質ごとに分けて取り扱われてきた木質バイオマスを総体として捉え、新たに有意な価値を発見することである。そこで、リグニン－糖複合体（LCC）に着目し、木粉からLCCを分離する際にその化学構造を損なわずに利用できる可能性を示した。社会的意義としては、木質バイオマスを有効に活用するための技術開発に寄与し、木質バイオマスの価値を高める可能性を広げた。本研究成果は、木質バイオマス利用関連産業において、持続可能な材料やプロセスの開発に貢献することが期待される。
