Fig. 1.

Color appearance of the PSI-less and PSI-less/ScpABCDE⁻ mutants grown in the presence or absence of 0.2 M NaCl. Cell cultures of PSI-less and PSI-less/ScpABCDE⁻ strains were in BG-11 supplemented with glucose in the presence or absence of 0.2 M NaCl as described in Material and Methods. The photo was taken after dilution at OD₇₃₀ 0.4–0.5. Representative cultures of three biological replicates are shown
