Spirulina is high in protein and other nutrients, finding use as a food supplement and for malnutrition. Previous studies of the photoprotection of various pigments in S. platensis were carried out in the presence and the absence of biopterin-a-glucoside to evaluate the photostability of these photosynthetic pigments in the photosynthetic vesicles that imdergo UV irradiation (Noguchi et ah, 1999).
