Extended Data Fig. 5: Control experiments for DCFH-DA and PI.
From: Community-specific cell death sustains bacterial expansion under phosphorus starvation
a, Snapshots of phase contrast (PH), DCFH-DA fluorescence (YFP) and PI fluorescence (mCherry) with or without the addition of DCFH-DA and PI. The white lines indicate the locations of biofilm edge. Scale bar, 100 μm. b, Effect of DCFH-DA and PI on biofilm expansion rate. n = 4 biological replicates. Error bars indicate mean values ± SD. Statistical significance was determined by two-sided Student’s t-test; ns, not significant, P ≥ 0.05.
