TECHNOLOGY FOCUS - BIOLOGY - Preferred Components: The starch-accumulating filament-forming or colony-forming algae is an algae in a phylum (such as Zygnemataceae, Cladophoraceae and/or Oeologoniales), preferably Spirogyra, Cladophora and/or Oedogonium. The animal waste is hog waste or poultry waste. The yeast is Saccharomyces cerevisiae or Saccharomyces uvarum.    TECHNOLOGY FOCUS - BIOTECHNOLOGY - Preferred Process: The decay is initiated mechanically. The decay is initiated by placing the biomass in a dark and anaerobic aqua environment. The growing step forms natural bloom of algae. The aqua culture is open to atmospheric conditions. The carbon dioxide level in the aqua culture is raised above atmospheric levels by the external addition of carbon dioxide. The separating step is started, when the level of ethanol in the fermentation solution is 12-17 volume%. The animal waste is used as a phosphate source in the aqua culture. The process further comprises: collecting the carbon dioxide generated during fermentation; supplying the collected the carbon dioxide to the aqua culture; isolating the lipids/oils present in the biomass after separation of the ethanol; and converting the isolated lipids/oils present into biodiesel. EXAMPLE - Water was pumped into the trenches or ponds from a natural (untreated) water source. The water was sampled for nutrient levels and then nutrients (phosphates and nitrates) were added. Spirogyra was then added to the nutrient rich water. The water was monitored for 2-4 weeks for algae growth rate and nutrient levels. The bloom was raked out of the trenches or ponds, when the Spirogyra reached bloom conditions, and some Spirogyra are left in the water for the next crop. The harvested algae was placed in a sealed tank with enough water to just cover the biomass and allowed to set. After the tank was filled, the air was pumped out of the tank and the contents were allowed to set for approximately 7 days. A sample of the biomass was removed from the tank and examined under a microscope to determine the cell degradation. Saccharamyces Cerevisiae yeast was added to the biomass, when the cells were begun to degrade. The fermentation process was monitored for the level of ethanol in the biomass liquid. The liquid was drained from the tank and pumped to a holding tank, when the liquid reached a level of 12-14% ethanol. Then the ethanol was separated from the fermentation solution.
