Fig. 3From: One-step production of C6–C8 carboxylates by mixed culture solely grown on COConcentration of carboxylate products in the reactor. a Even-carbon-number carboxylates (acetate, n-butyrate, n-caproate and n-caprylate). b Odd-carbon-number carboxylates (propionate, n-valerate and n-heptylate); c Branch-chain carboxylates (i-butyrate and i-valerate). The blocks labeled with I, II, III, IV, V, VI and VII indicate the seven phases during continuous feedingBack to article page
