Values of TTA (expressed as ml of 0.1 N NaOH) and amount of lactic and acetic acid (mg/100 g fermented BSG) synthesized at different time points (hours) during fermentation of control (EPS−) and sucrose supplemented (EPS+) BSG with Leuconostoc pseudomesenteroides DSM20193 (DSM20193) and Weissella confusa A16 (A16)
^a−dValues in the same column with different letters are significantly different (Tukey’s test. P < 0.05)
