<i>intIA</i> and cassette array expression during growth and according to growth conditions.

<p>β-galactosidase assays are performed with strains ω8320 (promoter cassette array:<i>lacZ</i>) (A and C) and ω7450 (integrase:<i>lacZ</i>) (B and D). In A and B, growth was performed at 29°C in M63 glucose casamino serine vitamin B1 (black), in Marine broth (grey) and in classical LB (striped). “expo” means exponential growth. In C and D, growth was performed in LB without NaCl, (-NaCl), with classical concentration (LB) or with high NaCl concentration (+ NaCl) and samples are harvested at the end of exponential growth.
