Patent ID: 8658772

Claim:
A method of selectively removing algal proteins from a wet freshwater algal biomass comprising intact algal cells or wet freshwater algal culture comprising intact algal cells, the method comprising: a. harvesting algae from the wet freshwater algal biomass comprising intact algal cells or wet freshwater algal culture comprising intact algal cells; b. dewatering the harvested algae to remove at least a portion of extracellular water from the harvested algae, to yield a first biomass fraction comprising intact algal cells; c. extracting said first biomass fraction comprising intact algal cells with a first solvent, yielding a second biomass fraction comprising intact algal cells and a first liquid phase; d. separating said second biomass fraction comprising intact algal cells from said first liquid phase; and e. concentrating said first liquid phase to yield a mixture enriched in algal proteins.
