Figure 1: Antifungal activity of endophytic Bacillus spp. against Fusarium oxysporum f. sp. lycopersici attributed to diffusible (a) and volatile (b) metabolites, cell-free filtrates from 2 to 4-day-old bacterial cultures (c) and organic extracts tested at two concentrations (d) as compared to controls. SV44: Whole cell suspension of Bacillus methylotrophicus str. SV44; FSV39: Cell-free culture from Bacillus tequilensis str. SV39; Ethanol: Negative control; F: Positive control (Bavistin®, chemical fungicide); Bio-F: Positive control (Bactospeine®, Bio-pesticide); ESV41: Chloroform extract from B. subtilis str. SV41.
