Establishment of the stable transformation system for a marine oil-producing alga, Pleurochrysis carterae (Haptophyta):
Future applications for biofuel production are expected

Coccolithophores (Haptophyta) are calcareous marine unicellular algae widely distributed in the world oceans, and some of them are considered to be the precursor of fossil fuels. Among those, a species Pleurochrysis carterae is regarded as a strong candidate feedstock for biofuel production because of its high lipid content and biomass productivity. Recently, Dr. Endo (PRESTO researcher, Japan Science and Technology Agency) and colleagues have succeeded in establishment of a stable transformation system for this alga. This newly developed technique is promising for alternative fuel production utilizing this marine microorganism.
