A. niger: Aspergillus niger, P. expansum: Penicillium expansum, B. cinerea: Botrytis cinerea, V. dahlia: Vercticillium dahliae. (+): weak antifungal activity having an inhibition rate between 40 and 70%; (++): strong activity with an inhibition rate ≥ 70%; the strains characterized with a broad range against different fungi appear in bold. Data were obtained at least three replicates. *Means within column show statistically significant difference () with a control (nonexposed to the bacteria).
