This was achieved by the addition of L-leucine and amyl alcohol in fermentations carried out by a high ester-producing brewing yeast strain of Saccharomyces cerevisiae and by the use of alkaline fermentation conditions coupled with high gravity media. Obtained flow regime of dispersed n-heptane droplets in a continuous buffer phase, which enables in situ extraction of the produced isoamyl acetate to the n-heptane phase, provides a very large interfacial area for the esterification catalyzed by an amphiphilic lipase B, which positions itself on the n-heptane—buffer interface. They are used as chemical intermediate to manufacture pharmaceuticals, synthetic flavorings, cleaners, and other organic compounds. Purified isoamyl acetate was used to confirm the retention rate of the compound (panel C). The performance of the Corning AFR™ Low Flow (LF) fluidic module for Candida antarctica lipase B-catalyzed isoamyl acetate synthesis in an n-heptane—buffer two-liquid phase system was evaluated.
