| Outline of Final Research Achievements |
Oil-producing microalgae produce oil such as lipid and hydrocarbon by utilizing solar energy and carbon dioxide (phosynthesis). Microalgal oil can become renewable and carbon-neutral next-generation energy. However, known oil-producing microalgae are not enough efficient to produce oil for mass production. Breeding method should be developed in microalgae for improving the productivity. We therefore aim to uncover the mechanisms of sexual reproduction of oli-producing microalgae for cross breeding and to search novel genetic resources in wild species and strains for materials of breeding. By genomic screening and gene expression analysis, we found an evidence of capability for sexual reproduction in an oil-producing microalga, Botryococcus braunii. We have also developed a PCR (polymerase chain reaction) based technique for detection and quantification of wild B. braunii strains from tropics to temperate regions.
