P. fluorescens kills M. xanthus when both species are pregrown and interact at 22°C but not when both are pregrown and interact at 32°C.

DK3470 population sizes are shown 24 hours after interaction with P. fluorescens when the 2 species interact at the same temperature at which both had been reared prior to interaction. Means of log₁₀-transformed CFU + 1 values and 95% confidence intervals are shown. Lighter dots are biological replicates (n = 3). *** p < 0.001 (Tukey-adjusted contrasts) for the difference between M. xanthus population size after interaction with P. fluorescens (green dots) vs. in the control treatment (black dots) when the 2 species were reared and interacted at 22°C. The dataset for this figure and the R script used to analyze it and make the figure are available on Zenodo (10.5281/zenodo.10214013).
