dc.description.abstractAims: Fungal diseases are one of the most important biotic factors causing serious losses in banana cultivation in field or greenhouses during cultivation, harvest, storage and transportation periods. Crown rot, caused by Fusarium verticillioides, is considered one of the most important postharvest fungal disease of banana fruits. In this study, endophytic bacterial isolates were obtained from fruits, branches and leaves of healthy banana trees and their antagonistic potentials were investigated against F. verticillioides as a biological control agent (BCA) in vitro conditions.Methods and Results: A total of 23 putative endophytic bacterial isolates were obtained from fruits, stems and leaves of healthy banana trees. All bacterial isolates were identified by MALDI-TOF MS (Matrix Assisted Laser Desorption Ionization-Time Of Flight Mass Spectrometry) analysis. In vitro antagonistic efficiencies of 12 different bacterial isolates, from eight different species (Bacillus subtilis ssp. spizizenii (3), Bacillus amyloliquefaciens (2), Bacillus subtilis ssp. subtilis (2), Bacillus mojavensis, Enterococcus faecium, Enterobacter cloacae, Enterobacter ludwigii and Pseudomonas stutzeri), were tested on inhibiting mycelial growth by using dual culture tests. Among bacterial isolates, the highest antagonistic activity was displayed by Bacillus mojavensis BEn3 isolate which significantly inhibited the mycelial growth by 50.83%. Enterobacter cloacae BEn1, Enterobacter ludwigii BEn2, Enterobacter faecium BEn7, however, failed to inhibit the mycelial growth of fungi.Conclusions: Significant suppression in the mycelial growth caused by endophytic bacterial isolates indicates that Bacillus mojavensis BEn3 isolate could be considered as possible BCA against crown rot disease agent.Significance and Impact of the Study: Our findings suggest that B. mojavensis Ben3, as the most successful endophyte bacterial isolate that suppresses the growth of F. verticillioides, can be used as a promising biological control agent as an alternative to chemical control against crown rot disease.en_US
