Table 2. Growth physiology parameters in cultures of UWO 241 and SAG 49.72 grown under control versus long-term stress conditions. Values are means with standard deviations (n=3 biological replicates). Superscript letters - a, statistical significance between control vs. stress within one algal species;b, statistical significance between UWO 241 vs. SAG 49.72 when grown under same treatment (p<0.05). FV/FM, maximum photochemical efficiency; qL, photochemical quenching.
Table 3. Gaussian fitting parameters for the subband decomposition of 77K Chl a fluorescence spectra of SAG 49.72 and UWO 241 acclimated to control versus long-term stress conditions.λMAX , maximum fluorescence emission peak (nm); Area %, percentage area of individual bands calculated from total area of all bands; FWHM, full width at half-maximum. PSII/PSI was calculated as the ratio of the areas of peaks λ1 and λ4.
