<i>E. coli</i> growth inhibition test.

<p>Specific inhibition by cell-free culture filtrates of <i>P. syringae</i> pv. syringae UMAF0158 and the derivative mini<i>Tn5</i> and insertion mutants strains grown in liquid minimal medium (PMS).</p>a<p>Toxic activity is expressed as the diameter of the inhibition zone (in mm). The average and standard deviation values were obtained from three replicates of three experiments.
