Hydrophobicity index for A1S_0112::Tn, A1S_0115::Tn and cpdA::Tn transposon insertion mutants. Hydrophobicity results were obtained by assessing the bacterial cell affiliation to xylene. The optical density of the cell suspension before (ODinital) and after (ODfinal) the addition of xylene was measured at 600 nm. All the transposon insertion mutant strains have reduced cell hydrophobicity compared to the parental strain. The cpdA::Tn(0249) mutant strain with a wild-type copy of cpdA has a hydrophobicity greater than the 17978hm parent strain. Bars indicate the standard deviation of three separate experiments. Asterisks indicate significant difference: two denotes a p-value <0.01 and three a p-value <0.001, as determined by a student t-test
