Luciferase activity and growth of the LMG18311 and the Δ rgg
strains containing the P
- luxAB and P
- luxAB transcriptional fusions, in CDM medium. The expression of the fusions was followed in strains cultivated in CDM medium, at 30°C (A) or at 42°C (B). Data are presented as the mean +/- standard deviation of three independent experiments. AU: luminescence arbitrary units normalized against the OD600nm of the cultures.
