Title: Subcritical water extraction of lipids from wet algal biomass

Patent ·
OSTI ID:1250461

Methods of lipid extraction from biomass, in particular wet algae, through conventionally heated subcritical water, and microwave-assisted subcritical water. In one embodiment, fatty acid methyl esters from solids in a polar phase are further extracted to increase biofuel production.
