Fig. 3From: Astaxanthin and eicosapentaenoic acid production by S4, a new mutant strain of Nannochloropsis gaditanaa Net oxygen evolution rate at different light intensities for WT and S4 mutant strains normalized on a chlorophyll basis. Experimental data were fitted with hyperbolic function. b Net oxygen evolution rate normalized on a cell basis. c Dark respiration rate normalized on a cell basis for WT and S4 mutant strains. Error bars showed the standard deviation (n = 3). Significant different values are marked with ** as determined by unpaired two-sample t-test (n = 3, p < 0.01)Back to article page
