Influence of the light source on the production of photosynthetic pigments. The wavelength dependence of pigment production was tested under the following cultivation conditions, which allowed a high expression of the photosynthetic apparatus in the respective strains: L. syltensis DSM 22749T was grown in SYMHC medium under an initial headspace gas atmosphere of 20% (v/v) O2, C. halotolerans DSM 23344T in SYM medium containing 0.5% (v/v) Tween 80 under air atmosphere and P. rubra DSM 19751T in defined medium containing 5 mM DL-malate under an initial headspace gas atmosphere of 12% (v/v) O2. The amount of produced BChl a is symbolized by red bars for L. syltensis DSM 22749T, blue bars for C. halotolerans DSM 23344T and green bars for P. rubra DSM 19751T. Each experiment was performed in duplicate and the shown values represent means of two measurements.
