FIG. 5.
Growth characteristics of the wild-type and mutant strains under photosynthetic conditions. Photosynthetic cultivations were performed at low light intensity (3 W/m2) in completely filled screw-cap glass tubes to minimize the repression effect of PpsR. Cultures were inoculated with aerobically grown cells. The levels of spectral complexes in the strains grown under the same conditions to an OD600 of 0.3 to 0.4 are given above the growth curves for B800-850 and (B875). OD600 = (Klett unit + 3.06)/102.04.
