In spirulina bes ides β-carotene, echinenone, cryptoxanthin, zeaxanthin and lutein, the exisence of α-carotene, hydroxyechinenone and euglenanone was confirmed, β-Carotene was most abundant in this blue-green algae. In crustacea, it was confirmed that β-carotene was a precursor of astaxanthin and converted to astaxanthin through the steps of cryptoxanthin, echinenone, canthaxanthin and phenicoxanthin. The color of zeaxanthin is red, spirulina would be a good additives for fish food to improve their red color.}, pages = {111--115}, title = {Comparative biochemistry of Carotenoids in algae IV : Carotenoids in Cyanophyta blue-green algae, Spirulina platensis}, volume = {23}, year = {} }
