The pathway is essentially a modified/reversed fatty acid oxidation pathway, using several analogous enzymes. [8], Isoamyl acetate is released by a honey bee's sting apparatus where it serves as a pheromone beacon to attract other bees and provoke them to sting. Compared to the batch reaction with only 60% conversion of n-butanol, the reactive distillation column can improve the conversion ofn- butanol (up to 93.6%) and the lipase-loaded packing storage in the reaction system at 70 C for 120 days verified that the conversions could still reach 72.5%.
