| 1. A process for forming ethanol from algae, comprising:
(a) growing starch-accumulating, filament-forming or colony-forming algae in an aqua culture environment;
(b) harvesting the grown algae to form a biomass;
(c) initiating decay of the biomass;
(d) contacting the decaying biomass with a yeast capable of fermenting it to form a fermentation solution; and,
(e) separating the resulting ethanol from the fermentation solution.
