Low dose UV-B radiation induced mild oxidative stress impact on physiological and nutritional competence of Spirulina (Arthrospira) species

Among the various Spirulina species, Spirulina maxima (S. maxima) and Spirulina platensis (S. platensis) are used mainly as human dietary supplements, whole food, and feed supplement in aquaculture, aquarium and poultry industries due to their potential nutritional and medicinal benefits. Therefore,...
