Abstract
The present disclosure generally pertains to methods for the harvesting of biomass, in particular algae, from dilute aqueous suspension. In one embodiment, the method comprises the steps of: adjusting the pH of the dilute aqueous suspension to cause disruption of the algal cell walls and exposure of the hydrophobic tails of the algal lipid bilayer; adding at least one organic solvent to the dilute aqueous suspension; and mixing the dilute aqueous suspension. The method may also include the steps of: waiting for formation of an organic layer from the dilute aqueous suspension; and recovering the organic layer. The organic layer rises to the top of the dilute aqueous suspension, allowing for mechanical separation or decanting of the organic layer.
