Lipolytic activity of supernatants of Xanthomonas campestris pv. vesicatoria (Xcv) strains grown in XVM2/gentamicin (XVM2/Gm) medium. Strains were the lipA mutant and the wild‐type, both carrying pBBR1MCS‐5 (lipA
–/pBBR1 and wt/pBBR1, respectively), and the lipA mutant carrying pBBR1‐lipA (complemented strain, lipA
–/comp). Results represent averages and standard deviations (SDs) (five replicates per treatment) of one experiment (of two with similar results). Different letters indicate statistical significance at P= 0.05 according to Tukey–Kramer test and analysis of variance (anova). cfu, colony‐forming unit; MU, 4‐methylumbelliferine.
