Comparison of five photosynthetic parameters derived from oxygen light curves (Webb et al. 1974) (n = 3 ± SD). UTEX2353: Entransia fimbriata; UTEX2793: E. fimbriata; CCAP329/1: Hormidiella attenuata. Significantly different means between the algal strains are indicated by capital letters [α; μmol O₂ h⁻¹ mg⁻¹ chl. a (μmol photons⁻¹ m⁻² s^–1)^–1; P _max: μmol O₂ h⁻¹ mg⁻¹ chl. a], small letters (I _c: μmol photons m⁻² s⁻¹; R: μmol O₂ h⁻¹ mg⁻¹ chl. a), and underlined small letters (I _k: μmol photons m⁻² s⁻¹). Comparison was performed by one-way ANOVA followed by Tukey’s post hoc test (P < 0.05)
