【摘要】 从我国内陆盐湖中分离、培育出 2株钝顶螺旋藻新品系 (Sp(NS) 2 0 0 1和Sp(NS) 2 0 0 2 ) ,具有一些国外品系所不具备的特性和品质。其中二十二碳六烯酸 (DHA)在螺旋藻中的发现在国内外还是第一次。这 2株新品系经中试和生产应用表明 ,是适合于工厂化生产的高产优质藻种。更多还原

【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.更多还原
