Abstract:In order to explore the feasibility and value of using marine microalgae as a new type of biological raw material in food，medicine，energy，and other fields，the new strain of microalgae，Chlorella sp.TIO-36，was selected as the research object.The yields of this microalga under different cultivation methods were compared.The biochemical composition，fatty acid composition，and lutein content of its products were detected.Additionally，the antioxidant capacity of the lutein extract from this microalga was evaluated.The results showed that Chlorella sp.TIO-36 grew rapidly and had a high yield.The algal powder was rich in protein，unsaturated fatty acids，and lutein.The lutein extract had an antioxidant effect and light damage resistance，which could effectively alleviate cellular oxidative damage.
