Membrane extraction for detoxification of biomass hydrolysates

► Ethanol yields are higher for biomass hydrolysates detoxified using membrane extraction. ► Successful removal of acetic acid, sulfuric acid, and furans. ► Organic phase successfully regenerated and reused. ► Toxicity of the organic phase must be minimized. ► Non-dispersive membrane extraction could be a low cost alternative for detoxification.
