【 摘 要 】

Dunaliella salina have got great attention in the nutritional, pharmaceutical and cosmetic companies because contain β-carotene. β-carotene functions as antioxidants and precursors of vitamin A and can treat tumors and cancer in humans. The content of β-carotene in D. salina can be increased by increasing salinity levels in the culture medium. The aim of this study was to determine whether increasing salinity may increas β-carotene content of phytoplankton D. salina. The research use data collection method with direct observation and then analyzed the result with descriptive method. The results showed that different salinity of media can influenced β-carotene content of D. salina. The highest β-carotene content of D. salina was at treatment B (30 ppt) which equal to 2.312 mg/L on 10thday. The production of β-carotene in D. salina can be increased was other environmental stress treatments in the form of stress-temperature, light and nutrients using.
