The effect of antifungal activity of culture filtrate (CF) of Bacillus pumilusstrain CCIBP-C5, an isolate from a phyllosphere of banana (Musa) leaves, was determined on Pseudocercospora fijiensischallenged banana plants. The CF was shown to decrease the fungal biomass and induce changes in banana plant. In this sense, at 70 days post inoculation (dpi), a lower infection index as well as a decrease in fungal biomass after 6 dpi was obtained in treated plants with respect to control ones. At the same time, changes in the activities of several enzymes related to plant defense responses, such as phenylalanine ammonia lyase, chitinases, β-1,3-glucanases and peroxidases were observed. These results indicate that B. pumilusCCIBP-C5 has a potential role for biological control of P. fijiensispossibly due to the production of antifungal metabolites. |
