A selection among four strains of nitrogen-fixing blue-green algae for the photoproduction of protein-rich biomass has been carried out. The effect of temperature and pH on growth has been determined for each strain, as well as their tolerance to extreme conditions. Attention has also been paid to doubling time, biomass productivity and chemical composition, especially with regard to nitrogen, protein and pigments. Anabaena sp., a phycoerythrin-rich strain, shows the widest tolerance to extreme values of pH and temperature, exhibiting besides the highest productivity (about 30 g (dry weight) m-2 day-1) in semicontinuos cultures illuminated at 300 W m-2 using 10 h light-14 h dark cycles. Under the same culture conditions, Nostoc paludosum, which contains phycocyanins as the major phycobiliprotein pigment, shows a productivity of about 20 g (dry weight) m-2 day-1. ABSTRACT.
