The present invention relates to novel isolated bacterial strains, which are members of the genus Paenibacillus, originally isolated from soil and which exhibit antagonistic activity against a wide range of pathogens and are capable of producing antimicrobial metabolites. It was found that the strains Lu16774 and Lu17007 belong to a new subspecies named Paenibacillus polymyxa ssp. plantarum, while the strain Lu17015 belongs to a new species, which is proposed to be Paenibacillus epiphyticus. The present invention also relates to microbial pesticide compositions comprising at least one of the aforementioned new bacterial strains, complete culture broth or a cell-free extract or a fraction thereof, or at least one metabolite thereof, and/or a mutant of at least one of said new bacterial strains having all the identification characteristics of the respective bacterial strains or complete culture broth, cell-free extract, fraction and/or metabolite of the mutant showing antagonistic activity against plant pathogens. The present invention also relates to a method for controlling plant pathogens or for suppressing or preventing infections by plant pathogens by the application of such a composition. The present invention also relates to the new type compounds (...). |
