From: Regulation of bacteria population behaviors by AI-2 “consumer cells” and “supplier cells”
Manipulation of “controller cells” in co-cultures a. The regulation of GFP fluorescence by consumer cells. b. The regulation of GFP fluorescence by supplier cells. The strain containig pTrcHisB co-cultured with reporter cells was used as the control and its GFP flourence indensity at the beginning was defined as 1. The error bar indicated the standard deviation and each experiments was carried out by three replicates. A two-tailed unpaired Student’s t-test was performed between control and samples. And significant results indicated by the star. Two stars: P ≤ 0.05; three stars ≤0.01
