Antimycotic activity of Bacillus amyloliquefaciens against fungi of vineyards soil origin

2009

Preliminary investigations on grapevines (cv Catarratto) with symptoms of “esca” allowed the isolation of different bacterial colonies (Alfonzo et al, 2009). A Gram-positive, spore forming isolate, able to inhibit fungal growth, was subjected to identification. On the basis of the whole 16S rRNA gene sequence, it showed a similarity of 99% with Bacillus amyloliquefaciens. There are numerous reports on the antagonistic activity of this species towards several phytopathogenic microorganisms. For this reason, the potential of the bacterial strain against the fungi commonly associated to the soil of vineyards (Alternaria alternata, Aspergillus ochraceus, Aspergillus carbonarius, Cladosporium cl…
