Effects of TDA supplementation on competition assays between P. inhibens strains and V. tubiashii RE22Sm. a Growth of sessile RE22Sm on a glass coverslip in co-culture with either the S4Sm wild type or the clpX mutant strain (WZ10) supplemented with or without TDA (10 μg/ml). b Single channel and merged confocal microscopy images of mixed biofilm development by OFP-producing strains of P. inhibens S4Sm (WZ02) or the clpX mutant (WZ12) with the GFP-producing strain of V. tubiashii RE22Sm (WZ103) on the surface of a glass coverslip at 48 h after addition of RE22Sm and TDA. c Growth of planktonic RE22Sm in co-culture system with either the S4Sm wild type or the clpX mutant strain supplemented with or without TDA (10 μg/ml). The data presented are averages of two independent experiments with each experiment done in triplicate. Error bars represent one standard deviation
