Abstract

Presented herein are exemplary systems and methods for extracting lipids from a wet algal biomass. An exemplary method comprises lysing a wet algal biomass with an insoluble granular lysing agent to create a lysate, creating a lipid-rich phase in the lysate, and separating the lipid-rich phase from the lysate. An exemplary system comprises a lysing station for creating a lysate from a wet algal biomass and a separation station for creating and separating a lipid-rich phase from the lysate. According to further exemplary systems and methods, ultrasound may be used in place of or in addition to a lysing agent to lyse the wet algal biomass.
