Abstract
The aim of the study was to determine the influence of total dissolvedsolids/salinity (mg L-1 TDS) on photosynthetic activity of Nodularia spumigena strain 001E isolated from Lake Alexandrina, SouthAustralia, using photosynthesis-irradiance (PI) curves. N. spumigena001E cultures were grown in ASM medium at a range of TDSconcentrations (360, 6,600, 13,200, 19,800, 26,400 mg L-1)at an irradiance of 30 μmol m-2 s-1 (PAR, 400–700 nm) at 25 °C. The PI relationship was determined at 25 °Cfor irradiances between 0 and 500 μmol photon m-2s-1 (PAR). The initial slope of PI curve, α, a function of lightharvesting efficiency and photosynthetic energy conversion, decreasedproportionally with an increase in salinity from 360 to 26,400 mgL-1 TDS. The maximum rate of photosynthesis (Pmax),occurred at 6,600 mg L-1 TDS. No influence of salinity onIk, the irradiance at which Pmax was measured, or on Rd, the dark respiration rate, was identified.
