Figure 1From: Cloning, purification, and functional characterization of Carocin S2, a ribonuclease bacteriocin produced by Pectobacterium carotovorumBacteriocin assays of Tn 5 insertion mutants of Pcc strains. Strain number: 1, 3F3 (wild type); 2, 1830 (E. coli); 3, F-rif-18 (parent); 4, TF1-1 and 5, TF1-2 (insertion mutant). Other unlabelled strains are Tn5 insertion mutants of F-rif-18 strain. The indicator is Pcc strain SP33.Back to article page
