Selective heated extraction of globulin proteins from intact freshwater algal cells
First Claim
Patent Images
1. A method of selectively extracting globulin proteins from a freshwater algal biomass comprising intact algal cells or freshwater algal culture comprising intact algal cells, the method comprising:
- a. mixing the freshwater algal biomass comprising intact algal cells or freshwater algal culture comprising intact algal cells with salt water and heating to generate a heated extraction mixture comprised of a liquid phase enriched in globulin proteins, and a solid phase; and
b. separating the liquid phase enriched in globulin proteins, from the solid phase wherein the solid phase comprises intact algal cells, and wherein the algal cells remain intact before and after the extraction.

Abstract
Methods for selective extraction and fractionation of algal proteins from an algal biomass or algal culture are disclosed. A method of selective removal of products from an algal biomass provides for single and multistep extraction processes which allow for efficient separation of algal proteins. These proteins can be used as renewable sources of proteins for animal feedstocks and human food. Further, lipids remaining in the algal biomass after extraction of proteins can be used to generate renewable fuels.
