Values are mean ± SD of three replicate analyses (n = 3). a–f Mean values within a row (comparison of the different LAB count: within the same LAB, at the different sugars’ concentrations. Samples enriched with glucose and yeast extract were compared with control whey samples; samples enriched with saccharose were compared between each other) with different letters are significantly different.
