Figure 2

Influence of tyrosine or tyrosine containing peptides on growth and tyramine production by Lactobacillus plantarum IR BL0076. Lactobacillus plantarum IR BL0076 was grown in MRS medium (control curve; dashed line), synthetic medium with free tyrosine (continuous line) or in medium containing synthetic peptides as the sole tyrosine sources (dotted line). Tyramine was assayed by HPLC after various times of growth of L. plantarum IR BL0076 (OD600nm = 1.0; 1.6; 1.8), in both culture media. Each value is the mean ± SD of three independent experiments.
