Abstract
Strain CF05 isolated from Cryptomeria fortunei in Tianmu Mountain, Zhejiang province was identified as Paenibacillus polymyxa on the bases of its phenotypical and biochemical characteristics as well as 16 S rDNA gene sequence. The P. polymyxa CF05 exhibited highly antagonistic effects against 9 plant fungal pathogens and 3 plant bacterial pathogens in vitro. Furthermore, both cell-free fermentation and bacterial suspension promoted tomato seedlings growth in greenhouse assay. Cell-free fermentation increased the biomass with fresh weight and dry weight by 272.0% and 266.7%, respectively. It was demonstrated that secondary metabolites from this bacterium might perform a critical function in plant growth promotion. Tests of root-colonizing ability indicated that concentrations of the bacterium in tomato rhizosphere were 3.8, 3.6, 3.1 and 3.1 log CFU/g root after 27 days of inoculation of tomato seeds with the bacterial suspension at 108、107、106、105 CFU/mL, respectively. Seed germination ratio was increased by 11.7%, and the disease incidence of damping-off was reduced by 38.6% after seed treatment.
