We developed a pipeline to extract and upgrade short chain carboxylates to esters via membrane electrolysis and biphasic esterification. Carboxylate rich broths are electrolyzed in a cathodic chamber from which anions flux across an anion exchange membrane into an anodic chamber, resulting in a clean acid concentrate with neither solids nor biomass. Next, the aqueous carboxylic acid concentrate reacts with added alcohol in a water-excluding phase to generate volatile esters. In a batch extraction, 96 ± 1.6% of the total acetate was extracted in 48 h from bio-refinery thin stillage (5 g.L-1 acetate) at 379 g.m-2.d-1 (36 % Coulombic efficiency). With continuously regenerated thin-stillage, the anolyte was concentrated to 14 g.L-1 acetic acid, and converted at 2.64 g (acetate).L-1.h-1 in the first hour to ethyl acetate by the addition of excess ethanol and heating to 70°C, with a final total conversion of 58 ± 3%. This processing pipeline enables direct production of fine chemicals following undefined mixed culture fermentation, embedding carbon in industrial chemicals rather than returning them to the atmosphere as carbon dioxide.
