Abstract:
:A bacterial strain named XHY-12 was isolated from corn soil samples and identified as Burkholderia sp. based on 16S rDNA sequencing, it displayed high antagonistic activity against 12 fungal pathogens and the common fungal contaminant in grain Aspergillus flavus. Plate experiment showed that XHY-12 fermentation broth reduced the incidence of S. sclerotiorum on detached rape leaves (Brassica campestris L.) by 100%, and a greenhouse experiment showed that it could promote the growth of rape seedlings with significant increases in plant height, root length, and fresh weight. Furthermore, a novel funding was the reduction of aflatoxin B1 and B2 by over 85% in 60 h, and the decomposition enzymes should be extracellular. The results suggest that XHY-12 has a potential for commercial applications as biocontrol, mycotoxin detoxification agent or biofertilizer.
