Total carotene, chlorophyll a, and chlorophyll b content (mg g−1) in algal samples (Cla, Cladophora rupestris; Furc, Furcellaria lumbricalis; Ul, Ulva intestinalis; Chlo, Chlorella vulgaris; Sp1, Spirulina (Arthrospira platensis) from University of Texas; Sp2, Spirulina (Ltd. “Spila“). a–c for the same analytical parameters, in macro- and microalgae groups, means with different letters are significantly different (p ≤ 0.05). A–E for the same analytical parameters, in all algal samples, means with different letters are significantly different (p ≤ 0.05)).
