Abstract
Hexanoic acid, a six-carbon straight-chain fatty acid, is found in trace amounts in various animal fats and oils. Its commercial use is primarily as a precursor for the synthesis of fine chemicals. In this study, hexanoic acid production from galactitol was investigated using microorganisms from activated sludge. For the production of hexanoic acid, sludge was treated at 100℃ for 30 minutes, and then it was used as an inoculum. The major products in liquor phase were acetic acid, butyric acid, and hexanoic acid. The concentration of acetic acid and butyric acid was about 0.5~2.5 g/L. Yield of produced hexanoic acid was about 0.35±0.1 g/ galactitol g. Using prolin as an osmo-protector, the concentration of produced hexanoic acid increased to 5~6 g/L.
