Effect of pH and inorganic carbon concentration on growth, glycerol production, photosynthesis and dark respiration of Dunaliella salina

Abstract

The growth of Dunaliella salina was studied with respect to pH and varying concentrations of NaHCO3 in the medium. The growth rate, photosynthesis and dark respiration were maximal at pH 8 and 4 mM NaHCO3 in the medium. Photosystem I of the Hill reaction was affected more by inorganic carbon concentration than photosystem II.
