Measurements of inhibition zone diameter (cm) generated by either Enterococcus sp. BE11 isolate cell-free supernatant (CFS) (black columns) or purified exopolysaccharide (BE11-EPS) (grey columns) against the listed fish pathogens. The agar well-cut diffusion results for Pseudomonas fluorescens are demonstrated after exposure to dimethylsulfoxide (DMSO) (A), or to CFS (B) or BE11-EPS (C). DMSO served as a negative control well. Both CFS and BE11-EPS led to the inhibition of bacterial growth. The error bars refer to the standard deviation of three independent measurements
