GABA production (mM) of 132 lactococci (▲ L. lactis, ♦ L. cremoris phenotype lactis, ● L. cremoris phenotype cremoris) after 24 h of growth on glucose-YE medium supplemented with 34 mM L-glutamic acid without NaCl (A) and with 0.3 M NaCl (B). Values represent the mean of duplicate experiments. The strains mentioned in the text are MG1363, a L. cremoris strain with a lactis phenotype ♦, and NCDO2118, NCDO2727, S642 and EIP3I, which are L. lactis strains▲
