Method of Rupturing Algae Cells - 1999 Patent

Abstract

A method for rupturing microalgae in an aqueous suspension is disclosed. In one embodiment the aqueous suspension is passed through a constriction into a liquid phase at a pressure sufficient to rupture the cells by circulating the aqueous suspension through a constriction in a pump loop at a pressure and a percent recycle sufficient to rupture the cells. Cells of the alga Dunaliella salina can be ruptured by the method of the invention to promote froth flotation and mechanical filtration of the cells for recovery of mixed carotenoids.
