Exploring the Potential of Bacillus amyloliquefaciens N33 in Biocontrol
Abstract
The use of biocontrol agents instead of synthetic chemicals in the control of plant diseases and post-harvest preservation of fruits, vegetables and cereals has gained great momentum given their numerous advantages. In the present study, the antifungal activity of Bacillus amiyloliquefaciens N33 strain isolated from lettuce was tested in vitro against Penicillium citrinum, P. expansum, P. verrucosum, P. digitatum, P. paneum, Fusarium graminearum and Aspergillus fumigatus. The strain showed a high activity against all tested fungi and the inhibition rate ranged between 60.3-94.2%. The highest activity was observed against P. digitatum (94.2%) and P. expansum (82.5%), which caused significant postharvest losses in fruits. In addition, N33 showed a higher activity against F. graminearum, P. digitatum, P. expansum and P. paneum than the synthetic fungicide. The findings indicate that B. amiyloliquefaciens N33 can be a broad spectrum biological control agent against different fungal species.
