  • Process for the production of ethanol from algae
    Patent number: 7507554
    Abstract: The present invention describes a process for the production of ethanol by harvesting starch-accumulating filament-forming or colony-forming algae to form a biomass, initiating cellular decay of the biomass, fermenting the biomass in the presence of a yeast, and the isolating the ethanol produced. The present invention further relates to processing of the biomass remaining after ethanol production to recovering biodiesel starting materials and/or generation of heat and carbon dioxide via combustion.

  • Process for the production of ethanol from algae
    Patent number: 7135308
    Abstract: The present invention describes a process for the production of ethanol by harvesting starch-accumulating filament-forming or colony-forming algae to form a biomass, initiating cellular decay of the biomass in a dark and anaerobic environment, fermenting the biomass in the presence of a yeast, and the isolating the ethanol produced. The present invention further relates to processing of the biomass remaining after ethanol production to recovering biodiesel starting materials and/or generation of heat and carbon dioxide via combustion.
