Figure 2. Effects of the retS mutation on antibiotic activity.

Figure 2

Antibiotic activities of P. protegens strains toward B. subtilis (A), P. ultimum (B) and F. oxysporum (C) were evaluated by the size of the growth inhibition zone. Antibiotic activities of P. protegens Cab57 wild type (WT) and the retS mutant (ΔretS) were compared.
