Provided are methods, systems and apparatuses to the energy efficient and selective extraction of biomolecules, e.g., small organic compounds, e.g., one or more C3- C9 alcohols, one or more C3-C5 carboxylic acids, and mixtures thereof, from an aqueous solution, particularly aqueous solutions containing the alcohol in dilute or low concentrations, for example, fermentation broths. |
