Time course of cell growth and <i>gelE</i> promoter activity.

<p>Growth of the GBAP-negative <i>E. faecalis</i> OU510 with 3% NaCl (○) compared to medium without salt added (•), and promoter activity in response to addition to equal amounts of GBAP measured as RLU (▪ = no NaCl, □ = 3% NaCl). All the values are the means from two independent experiments.
