| Outline of Final Research Achievements |
Rhodococcus erythropolis N9T-4 is a super oligotroph, which can grow on a minimum medium without any additional carbon, nitrogen, and sulfur sources. This bacterium can incorporate such nutrients from the atmosphere including CO2,while the mechanisms are still unclear. In the first part of this study, we identified some genes involved in the oligotrophic growth of N9T-4. In the second part, we attempted to construct low-carbon and low-cost bioprocess for biofuel, such as ethanol and triacylglycerol using the oligotrophy of N9T-4.

| Academic Significance and Societal Importance of the Research Achievements |
超低栄養性細菌は本研究代表者が発見した微生物であり，世界でもほとんど研究例がない．本研究において，その低栄養性に関与するいくつかの遺伝子の機能を明らかにできたが，それらは全く新しい知見であり学術的意義は非常に高い．また，本菌の低栄養性を用いた低炭素・低コストなバイオ燃料生産プロセスの構築に向けた基礎的な知見も得られ，これらはSDGs（持続可能な開発目標）の目標のうちの１つ，「エネルギーをみんなにそしてクリーンに」の達成に寄与するものである．
