Abstract
Methods for the extraction of intracellular contents from biomass, in particular from algae, are described. The pH level of the algae cell culture is modified and mixed with a surfactant or a combination of surfactants. The algal culture may be subjected to low pressurization using air, inert gas or a gas mixture. Separation of the lipid contents from the treated algae culture is accomplished with an organic solvent or a mixture of organic solvents. The algal debris may be collected at the bottom of the aqueous phase while the biomass is concentrated in the solvent layer.
