Inhibition of F. solani mycelial growth (diameter in cm) by bacterial isolates from: a extremophile soils (strains’ names with E), b agricultural soil (S), c soils contaminated with hydrocarbons (EH), and d air samples (A). Average values are shown with standard error, * indicates significant difference relative to control (c at the extreme right of each plot) (Kruskal–Wallis’s test p ≤ 0.01). e Five-day culture assays of fungus (circle at the center) with bacterial isolates (inoculated in the lines 1.5 cm above and below the fungus circle). These isolates were based on a ≥ 40% inhibition
