OriginOil Completes and Looks To Patent Live Algae Oil Extraction Process
Los Angeles, United States
OriginOil Inc. announced that it has succeeded in extracting algae oil on a continuous basis without cell sacrifice. This new "milking" process could join the company's Cascading Production technique to create a combined cycle promising new efficiencies.
Algae typically protect their oil behind a tough cell wall. The challenge of live extraction is to harvest the oil without causing permanent damage to the cell.
The company's Live Extraction process, or "milking", is designed to achieve continuous production of algae oil without destroying the algae cell. Therefore a single algae cell can produce more oil during its lifetime using lower amounts of energy. OriginOil’s process does not employ consumables such as reverse osmosis membranes and it is not limited to oil-bearing algae strains, such as Botryococcus braunii, that are known to excrete algae oil naturally.
Algae typically protect their oil behind a tough cell wall. The challenge of live extraction is to harvest the oil without causing permanent damage to the cell. This goal has been achieved in the laboratory at bench scale and is now being scaled up to OriginOil’s intermediate 200-gallon tank size.
The company recently filed for patent protection of the new Live Extraction process, its ninth patent application, entitled “Procedure for Extraction of Lipids from Algae without Cell Sacrifice.”Aw. Not Exxon.
