Title: Moisture displacement and simultaneous migration of surface-functionalized algae from water to an extraction solvent using ionic polyelectrolytes

Abstract

This invention is in the field of micro-organism and algal cell processing. The invention relates to a method of maximizing migration of micro-organism and/or algal cells to a solvent fraction while simultaneously displacing water in a separate fraction and subsequent extraction of hydrophobic products from the organisms. The invention further relates to a method of sequestration of protein from an aqueous phase to an organic solvent.
