Unmasked β-galactosidase activity as indicator of cell lysis of Congo Red non-binding derivatives of the colR -deficient strain. The data present percentage of β-galactosidase activity, measured from non-permeabilized cells against the total β-galactosidase activity determined from permeabilized bacteria. Results for P. putida PaW85 (wt), colR-deficient strain (colR), and for different transposon insertion derivatives of the colR mutant are shown. Bacteria were grown for 24 hours on solid 0.2% glucose M9 minimal medium containing 1 mM phenol. Data (mean ± standard deviation) of at least three independent determinations are presented.
