Antagonistic activity of B. subtilis PTA-271 toward the N. parvum strain Np-Bt67. The beneficial bacterium PTA-271 (Bs) and the N. parvum strain Np-Bt67 (Bt67), co-inoculated on the opposite sides of PDA plates, were incubated at 28°C (A) or 22°C (B). Pictures of representative plates among nine were taken from 4 to 13 days depending on mycelial growth. Top photographs are the plates without bacteria (pathogen control) and bottom ones are the plates co-inoculated with pathogen and Bs. Antagonism effect is characterized by an inhibition zone between the bacterial colony (right side) and the fungus (left side).
