International Energy, Inc. has announced the development of a continuous cyclic growth and hydrocarbon extraction process that can be applied to mass cultures of microalgae for the separation of bio-oils from the algal biomass. This technology yields high purity microalgal bio-oils, which can serve as feedstock for the production of biofuels.

International Energy has successfully identified proprietary microalgae that photosynthesize carbon dioxide (CO2) and water (H2O), and naturally accumulate up to 30% of their dry biomass in the form of liquid hydrocarbons. The latter can be easily converted into a variety of biofuels.
