Figure 9From: A simple model for the early events of quorum sensing in Pseudomonas aeruginosa: modeling bacterial swarming as the movement of an "activation zone"Properties of cell agents. A) Description of the algorithm carried out by the agents at each time point. At 'STOP', the cells irreversibly enter a metabolically inactive stationary state. The functions depend on the state of activation of each mutant and these are regulated in a threshold-based manner by the signal levels. B) Energy balance of the various mutants studied. The numerical values are shown in Table 1 and described in the Additional file 1. "Swarming state" includes two states (with S production "on" [swarming level] or "off" [solitary level]) (Table 1).Back to article page
