  1. Wild-type and keaA- cells were washed, ressuspended in phosphate buffer to 1 × 107 cells/ml and starved in liquid suspension for 2 hours. At this point 80 nM of cAMP was added every 6 minutes for 4 hours. The number of isolated cells was counted and the percentage to the total number of cells was calculated.
