Outline of Final Research Achievements |
In this study, we developed a platform microorganism capable of supplying sufficient quantities of various precursor groups, thereby developing a fundamental technology to improve the productivity and yield of various useful compounds produced using microorganisms. Metabolic pathways contain a vast number of branching and joining points where carbon partitioning occurs. We have succeeded in increasing the production of 1,2-propanediol and resveratrol by breaking up pathways, combining pathways, and improving yields by using various carbon sources, demonstrating the usefulness of this technology.

Academic Significance and Societal Importance of the Research Achievements |
本研究で化合物ごとにそれぞれ最適な経路を再設計することができるようになり、様々な化合物のビルディングブロックとなる化学物質の理論収率を向上できる。さらに、近年メタノールやCO2を独立炭素源として菌体の生育を可能にするという研究が発表されており、本研究の技術と組み合わせてこれらの炭素源を物質生産へ利用することで、低炭素社会の実現や地球温暖化等の環境問題の解決に貢献できる。
