Sensing
Killing - Colicin
Time series of killer and prey bacteria. The intial ratio after 12 hours is 1:1, shown on the left image. Killer cells are marked with mCherry (red) and prey bacteria are marked with GFP (green). Many bacteria are grown after 44 hours (right image). However, the faint green fluorescence (it is sharp!) indicates the weak prey metabolism due to the toxin. Toxin production and excretion is activated in killer bacteria by the signaling molecule autoinducer-1 (not shown here).
