β-galactosidase actvity of R. sphaeroides strains harboring the reporter plasmid pPHUphrAlacZ. Cells were grown in aerobic conditions in the dark and were exposed to high light intensity (880 W m− 2) and 50 nM methylene blue (a) or to 360 μM of t-BOOH (b) for the indicated time periods. The mean of three experiments and standard deviations are shown. * indicates a significant change (P ≤ 0.05), ** indicates a highly significant change (P ≤ 0.01) according to Students t-test
