Recovery of carboxylic acids produced by fermentation
TL;DR: In-situ removal of carboxylic acid by extraction during fermentation is the most popular approach, but recovery of the extractant can easily lead to waste inorganic salt formation, which counteracts the advantage of the in-Situ removal.

L(+)-tartaric Acid Separations Using Aliquat 336 in n-Heptane, Kerosene, and 1-Octanol at 300 ± 1 K
TL;DR: In this paper, a 1:1 acid-amine complex was proposed for all the diluents with no overloading, that is, z < 0.5, and the equilibrium results were discussed in terms of the overall equilibrium complexation constant (KE(1:1)), loading ratio (z), extraction efficiency (E), distribution coefficient (KD), dimerization coefficient (D), and partition coefficient (P).
