• We had extracted n -caproate from bioreactor broth. Here, we introduced in-line membrane electrolysis that utilized a pH gradient between two chambers to transfer the product into undissociated n -caproic acid without chemical addition. Due to the low maximum solubility of this acid, selective phase separation occurred, allowing simple product separation into an oily liquid containing ∼90% n -caproic and n -caprylic acid. A membrane electrolysis system that was coupled with a bioreactor and pertraction system accomplished phase separation of oil, which consisted of >90% medium-chain carboxylic acids, without addition of chemicals.
