In a medium containing sodium propionate, pentanoic acid was produced by Megasphaera sp. BS-4 during anaerobic fermentation of fructose. Statistical optimization of medium was carried out in order to find a medium composition for the highest production of pentanoic acid by Megasphaera sp. BS-4. According to one-factor-at-a-time (OFAT) experiments, pH and two substrates, acetate and propionate, were found to have prominent effects on the pentanoic acid production. Especially, the concentration of propionate significantly influenced the production of pentanoic acid. As the initial concentration of sodium propionate increased, pentanoic acid production also increased. Meanwhile, acetate concentration influenced cell growth of Megasphaera sp. BS-4. But high concentration of acetate also stimulated the production of hexanoic acid, not intended to produce in this study. The production of pentanoic acid increased to 10 gL-1 in a medium containing 20 gL-1 fructose and additional two substrates, 3 gL-1 of sodium acetate and 15 gL-1 of sodium propionate. Further statistical experiments followed by Response Surface Methodology (RSM) were conducted for the understanding of optimum medium composition.
