[Use of microalgae for nutritional purposes]

Mass cultures of planktonic microalgae can render large quantities of proteinaceous matter. The good nutritional quality of microalgal protein has been proven both for animals and for human. The toxicologic safety of microalgal biomasses is, however, not yet sufficiently established. This requires further toxicologic studies, before cultivated mocralgae can commercially be utilized as ingredients of animal feed, or as food additives. Both types of nutritional application may become economically feasible.
