FIG 3 — Strain competition in biofilms. Shown are 15-h biofilms developed in a microfluidic BioFlux device as a result of competition between A026 and A018. A026 dominated in the biofilm competition of A018 versus A026 and A018 ΔR versus A026 regardless of the fluorophore (mCherry or GFP) used to tag either strain (A to D). However, A018 dominated when in competition with the null-R mutant of A026 (A026 ΔR) (E and F). (A) A026_mCherry versus A018_GFP. (B) A026_GFP versus A018_mCherry. (C) A026_GFP versus A018 ΔR_mCherry. (D) A026_mCherry versus A018 ΔR_GFP. (E) A026 ΔR_GFP versus A018_mCherry. (F) A026 ΔR_mCherry versus A018_GFP.
