Haslea species come from widespread geographic locations, and present different autecological, pigmentation and physiological traits, which could be used to optimise their culture in photobioreactors (PBRs), predict the responses of these organisms to global change (temperature, CO2, pH), and thereby select strains for particular solar PBR applications. Study of photoadaptation capacities and photoacclimation strategies will be possible comparing species and strains from the same genus but originating from different geographic areas, from the Arctic to the Equator.
