Table 1.

pH measurement of culture media and CFSs used in the study.

	pH
LB medium	6.6
MRS medium	6.1
TIL medium	6.8
CFS from LR06 cultured in MRS	4.4
CFS from LR06 cultured in TIL	4.3
CFS from LJO02 cultured in MRS	4.2
CFS from LJO02 cultured in TIL	4.0
LB + CFS from LR06 cultured in MRS/TIL	4.4
LB + CFS from LJO02 cultured in MRS/TIL	4.3

pH values of LB, alone and plus an equal volume of each one of the CFSs produced by the LAB in MRS and TIL media. The pH of pristine MRS and TIL broths is also shown.
