Unmasked β-galactosidase activity as indicator of cell lysis. 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) and colR-deficient (colR) strains measured at 24, 48 and 72 hours are shown. Bacteria were grown for three days either on solid or in liquid M9 minimal medium with 0.2% glucose (glc) or gluconate (gn) as carbon sources. Data (mean ± standard deviation) of at least three independent determinations are presented.
