摘要:
Paenibacillus polymyxa strain ATCC 202127 capable of producing a peptide antibiotic against fungi, and specifically Leptosphaeria spp. is disclosed. Further, mutants of said strain capable of producing the peptide are also disclosed. In addition, a method of controlling a fungal disease of a crop is disclosed. The method comprises applying an amount of the strain or mutants thereof to at least one of a medium for growing the crop, seeds of the crop prior to planting, and plants of the crop. The strain can also inhibit the growth of bacteria such as Micrococcus spp., Streptomyces spp. or Escherichia spp. The fungi which the strain or mutants thereof capable of producing the peptide are effective against include in addition to Leptosphaeria spp., the fungus selected from Sclerotinia spp., Rhizotonia spp., Pythium spp., Fusarium spp., Alternaria spp., Aspergillus spp., Sporobolomyces spp., Trichoderma spp., Penicillium spp. or Marasmius spp.
