| Summary: | Because bacterial isolates from only a few genera have been developed commercially as biopesticides, discovery
and characterization of novel bacterial strains will be a key to market expansion. Our previous screen using
plant bioassays identified 24 novel biocontrol isolates representing 12 different genera. In this study, we characterized
the 3 isolates showing the best biocontrol activities. The isolates were Pantoea dispersa WCU35, Proteus
myxofaciens WCU244, and Exiguobacterium acetylicum WCU292 based on 16S rRNA sequence analysis. The
isolates showed differential production of extracellular enzymes, antimicrobial activity against various fungal or
bacterial plant pathogens, and induced systemic resistance activity against tomato gray mold disease caused
by Botrytis cinerea. E. acetylicum WCU292 lacked strong in vitro antimicrobial activity against plant pathogens,
but induced systemic resistance against tomato gray mold disease. These results confirm that the trait of
biological control is found in a wide variety of bacterial genera |
