FIG 7.

Effect of nutrient levels on the interaction between P. fluorescens Pf0-1 and Pedobacter sp. V48, looking at 3 core components of TSB: tryptone (20 g/liter), d-glucose (2.5 g/liter), and NaCl (5 g/liter) for “high” concentrations. Components were reduced to 1/10 for “low” concentrations. For all panels, Pedobacter monoculture is on the top left of the plate, P. fluorescens is on the top right of the plate, and the mixed colony is in the center. Pictures were taken 144 h after inoculation. Colonies were grown on 100-mm petri dishes.
