Abstract:Two new strains (Sp (NS) 2001 and Sp (NS) 2002) of Spirulina (Arthrospira) were isolated and cultivated from the inland alkaline lake in China. The optimal temperature for growth is around 20℃, and they grow well even under 15℃. But the optimal temperature for common used strains from oversea are 30-35℃, and they can not grow under 15℃. The native new strains contain more polyunsaturated fatty acids, especially their DHA (docosahexaenoic acid, C 22 : 6) content ranges from 7.88-9.54 mg/g. It is the first time to find DHA in Spirulina. It was proved by large scale culture that these 2 new strains have higher yield and better quality, and are suitable for industrialization.
