Fig 1. Inhibition of growth of A. fabrum C58 by bacterial antagonists in vitro.

Diameters (in mm) of the inhibition zones caused in plates carrying A. fabrum C58 by the Tunisian Bacillus isolates MBY2, MBY9, and MBY11 as well as the commercial biocontrol strains A. radiobacter K84 and K1026 were determined by both the double layer and the well diffusion method after 48 h at 25°C. Error bars display the standard deviation of three biological replicates performed for each method.
