Outline of Final Research Achievements

Novel design for the bioprocess of hydrophobic molecule production was achieved in this study. The oil accumulation organelle, oil body, in the oleaginous diatom Fistulifera solaris was utilized as a reaction and storage space for the hydrophobic molecule production. Toward this goal, first, oil body-associated proteins were identified by the proteome analysis of the oil body fraction extracted from F. solaris. Using an identified protein as an anchor molecule, oil body-display technology was established. Subsequently, production of hydrophobic polyunsatulated fatty acids (PUFAs) was enhanced by genetic engineering. It was suggested that the produced PUFAs were partitioned into the oil bodies in F. solaris. These techniques can contribute to the efficient production of various hydrophobic molecules in microalgae.
