  1. NB: OD, optical density; SD, standard deviation; L, lactic acid bacteria isolates; Y, yeast isolates and the numbers next to the letters represent the isolate number; means with different superscript letters in the same column for the LAB and yeasts separately are statistically significant at p < 0.05.
