Synergistic Effects of Light and Salinity on Carotenoid and Biomass Composition of <i>Synechocystis</i> PCC6803 Cultures.

ABSTRACT: Light and salt stress affect the growth of plants and microorganisms, causing photo-oxidative stress. The cyanobacterium Synechocystis is notable for its adaptability to and sustainability in seawater. In this study, the synergistic effects of different light intensities and salt concentrations on the growth and biomass composition of Synechocystis were examined. Cultures were grown in BG11 medium (control) and with 20 and 40 g L^-1 marine salts (obtained from a commercial sea water preparation) at 100, 200, and 400 μmoles photons m^-2 s^-1 (LL, ML, and HL, respectively) to assess the interactive effects of salinity stress and increasing light intensity. The effect of salinity stress was most pronounced under LL and ML, where the highest accumula
