Abstract: In this work, litch residues left after manufacturing of litchi wine were fermented to produce ethanol and the fermentation process was optimized using response surface methodology. Ethanol production was explored with respect to pH, temperature and time. The optimal fermentation conditions were pH of 4.6 and temperature of 33 ℃ for a fermentation period of 70 h. Under these conditions, the ethanol production was up to 8.99 mL/100 g.

Key words: fuel ethanol, litch residue, fermentation, response surface methodology
