Outline of Final Research Achievements

This study clearly demonstrated the effect of hemicelluloses on ligninfication through lignin formation in the artificial polysaccharide matrices; xylan contributed to lignin formation and generation of 8-O-4' interunitary linkage, which was a major linkage in native lignin, while glucomannan inhibited lignin formation. In addition, xyloglucan, which located only at primary wall of tree, was found to enhance the frequency of 5-5' interunitary linkage.
From the analysis of solution structure for isolated lignins by using size-exclusion chromatograph equipped with multi-angle laser light scattering detector, 5-5' linkage was found to be closely related to the densed structure, especially much compact structure of lignin fraction with larger molar mass compared to that with small molar mass.

Academic Significance and Societal Importance of the Research Achievements

リグニンの形成とヘミセルロースとの関係について、これまで種々の仮説が提案されてきたが、本研究により、主要な細胞壁ヘミセルロースであるキシランとグルコマンナンの機能の違いが明確になった。さらに、現象論的には分かっていたが、直接的な関与が不明であったキシログルカンと一次壁リグニンとの相関も明示された。加えて、単離リグニンが低粘度である理由も、リグニンの縮合構造に起因することが示された。
これらの知見は、細胞壁構成成分の合目的機能を解明するという学術的意義に加え、単離リグニンを工業的に利用するための基本的情報の付与にも繋がり、資源持続型社会の構築にも貢献する社会的意義が見出せる研究となった。
