| Outline of Final Research Achievements |
It is necessary to produce hydrocarbon-based oils by photosynthetic organisms for a sustainable society. The haptophyte Tisochrysis lutea synthesizes long-chain alkyl ketones (alkenones), which can be substituted for petroleum. We applied random mutation by heavy-ion beam irradiation to improve the alkenone productivity. Alkenone is a stable compound found in marine sediment. Decades ago, it was shown that alkenones are produced by microalgae called haptophytes. It is known that only five species of haptophytes produce alkenones, and their assimilation and dissimilation pathways are still unclear, so we aimed to improve productivity through random mutation.
