FIG. 2.

Growth and expression of LAP in L. monocytogenes F4244 cultured in LB medium with different concentrations of dextrose and with or without K₂HPO₄ (2.5 g/liter). (A and B) Cell density of L. monocytogenes grown in LB with glucose only (A) or with both glucose and K₂HPO₄ (B). (C and D) Final pH after overnight growth of L. monocytogenes in LB with glucose only (C) or with both glucose and K₂HPO₄ (D). (E and F) ELISA results showing LAP expression in L. monocytogenes when grown in LB with glucose (E) or with both glucose and K₂HPO₄ (F).
