Simultaneous high-biomass protein production and nutrient removal using Spirulina maxima in sea water supplemented with anaerobic effluents.

Maximum protein accumulation (71%, w/w) and nutrient removal by a mutant strain of Spirulina maxima growing on sea water supplemented with anaerobically treated pig slurry was achieved at 30°C with constant illumination (60 to 70 μEm(-2)s(-1)), using a flow rate of 14.5 cm s(-1) (20 rev. min(-1) of a paddle wheel). Total phosphates were decreased by 99% and all ammonia-N was removed under these conditions.
