Lactococcus lactis ssp. cremoris strain MG1363 + pLP712 plasmid cultivated in LM17 at 30°C under O2 condition (black lines) and N2 condition (grey lines) for [1.] dissolved oxygen concentration (—) and redox evolution (−−−), for [2.] growth kinetics: enumerations (—) and OD
(−−−) and for [3.] acidification kinetics. Values are means of biological independent triplicates (n = 3) and bars represent the standard deviations.
