Sacch. cerevisiae KCCM 12684 seeds were innoculated by 5.0% (v/v) into makgeolli and fermented at 25℃ for 7 days.
All values are means±SD of determinations in three independent experiments. Means with different lowercase letters (a, b, c, d, and e) indicate significant (p<0.05) differences of fermentation times by Tukey’s multiple range test.
