Summary
Spirulina platensis has been grown in an outdoor pilot production unit, with an exposed surface area of 450 m2, on a medium consisting of raw domestic sewage supplemented with sodium bicarbonate and nitrate or urea fertilizer. The chemical composition and yield of the biomass grown on sewage-nitrate was comparable to that grown on synthetic medium. The protein content was much lower in the alga cultivated in sewage-urea medium.
