  1. Data presented are mean values based on two replicate fermentations. Error bars indicate standard deviations
  2. aAsterisks indicate statistically significant differences (P < 0.05) of the corresponding values obtained from cells grown on FOS or GOS compared with those grown on glucose
  3. bOctothorpes indicate statistically significant differences (P < 0.05) of the corresponding values obtained from ΔsacR1 or ΔsacR2 mutant compared with those of wild-type
