ABSTRACT
In this studyï¼ an endophytic bacteria strain BZJN1 was isolated from Atractylodes macrocephalaï¼ and identified as Bacillus subtilis by physiological and biochemical tests and molecular identification. Strain BZJN1 could inhibit the growth of mycelia of Ceratobasidium sp. significantlyï¼ and the inhibition rate was more than 70%. The mycelium growth deformity with bulge as spherical and partially exhaustible in apex or central with microscopic observation. The inhibitory rates under 3% and 6% concentrations of the cell free fermentation were 22.7% and 38.7% expectively. The field test proved that the control efficacy of treatment of 1×108 cfu·mL⻹ is 75.27% and 72.37% after 10 and 20 days. All the treatments of strain BZJN1 was able to promote the growth of A. macrocephalaï¼ the treatment of 1×108 cfu·mL⻹ could able to increase the yield to 14.1%.
