Phenotype and growth of B. velezensis GA1 following confrontation with different Pseudomonas strains. (A) B. velezensis GA1 (left colony) phenotypic response on solid CAA medium following short distance (1 mm) confrontation with different Pseudomonas strains (right colony). The control (CTRL) colony shows GA1 cultured alone. (B) GA1 growth curve in EM liquid medium supplemented with 4% (vol/vol) of different Pseudomonas cell-free supernatants. The control (CTRL) corresponds to unsupplemented GA1 culture (data represent means ± standard deviation [SD]; n = 9). (C) White line formation (indicated by arrow) between colonies of GA1 (left colony) and some Pseudomonas strains (right colony) on jellified CAA medium following longer distance (5 mm) confrontation. (D) GA1 (left colony) motile response on EM medium following confrontation with different Pseudomonas strains (right colony). The control (CTRL) colony shows GA1 cultured alone. Pictures in panels A, C, and D are representative of the response observed in three independent repetitions with three technical replicates (n = 9).
