A marine red microalga <i>Porphyridium</i> is considered as the potential feedstock for phycoerythrin production. However, the phycoerythrin-related properties of <i>Porphyridium</i> have not been systematically evaluated, especially between the species of <i>P. cruentum</i> and <i>P. purpureum</i>. The present study aimed to evaluate the production and fluorescence characteristics of phycoerythrin of three strains of <i>Porphyridium</i>. The results showed that <i>P. purpureum</i> SCS-02 presented the highest biomass, phycoerythrin content and yield were 6.43 g L^-1, 9.18% DW and 0.288 g L^-1, respectively.
