| Type of claims | Publication |
| Overview | This patent discloses a method of producing biofuels from algae. The system includes a feed biomass source, algae growth reservoirs, a sugar separator, an oil extraction bioreactor, and a conversion reactor. This integrated system advantageously uses a minimum of external inputs other than sunlight, water, and carbon dioxide to produce biodiesel. The method includes, A) cultivating an oil-producing algae by promoting sequential photoautotrophic and heterotrophic growth, B) achieving heterotrophic growth of algae by introducing a sugar feed to the oil-producing algae, and producing oil, C) extracting an algal oil from the oil-producing algae and D) converting the algal oil to form biodiesel. |
