Spirulina platensis was cultured in the laboratory to determine the range in conditions under which it may be cultivated in outdoor ponds. Efforts were made to reduce the cost of mass production through recycling of basal medium, reducing amount of nutrient supplemented, and substituting sodium nitrate with the cheaper potassium nitrate. The amount of solar radiation appeared to play an important role in determining the yield obtained. The harvests compared favorably with the FAO standard protein in amino acid content. The relative nutritive value was higher with sodium nitrate as source of nitrate. Sodium nitrate also enhanced the relative nutritive value of Spirulina. The thiamine, riboflavin and niacin contents exceeded those of soybean.
