Results represent the mean value±S.D. of three replicates. Mean values in the same row with the same letter are not significantly different (p<0.05) SC=fermentation with Saccharomyces cerevisiae 87 alone, LT×SC= mixed fermentation with Lachancea thermotolerans 617 and S. cerevisiae 87, LT…SC=sequential fermentation with L. thermotolerans 617 followed by S. cerevisiae 87
