V. fischeri ES114 culture fluids prevent growth of vibrio species in minimal marine medium. A. Representative V. harveyi BB120 cultures (left) and the corresponding optical density (OD₆₀₀) readings (right) following growth for 16 h in minimal marine medium supplemented with 10% (v/v) of the indicated culture fluid. ES114 and MJ11 denote V. fischeri ES114 and V. fischeri MJ11, respectively. For the no addition control, 10% (v/v) sterile minimal marine medium was supplied instead of culture fluids. B. Growth of the indicated bacterial species after 16 h in minimal marine medium supplied with 10% (v/v) sterile minimal marine medium (black) or 10% (v/v) culture fluids from V. fischeri ES114 grown in minimal marine medium (gray). In A and B, error bars represent standard deviations for three biological replicates. Unpaired two-tailed t tests were performed comparing the treated conditions to the no addition controls. P-values: ns ≥ 0.05, **** < 0.0001.
