Primary Studies on Application of Choline Chloride in Culturing of Spirulina platensis

螺旋藻是联合国粮农组织和联合国工业发展组织推荐的营养保健品，它的丰富营养物质和明显的药效作用已引起国际上的广泛重视，被誉为明天最理想的保健品和超级食品［1，2］.近来螺旋藻产业在国内外形成了一定的规模，但也存在着生产成本高的问题，如何降低生产成本已成...Spirulina platensis was grown in Zarrouk′s meida with low NaHCO 3 content (5～2 g/dm 3), anf effects of growth hormone, choline chloride(CC) on growth, biomassa and biochemical composition were studied.The results showed that S.Platensis could grow very well at the condition of 4 g/dm 3 NaHCO 3 with 10.0 mg/dm 3 CC ; biomass, protein and total carbohydrate contents were also increased to some extent.Low concentration of NaHCO 3 (10.0 g/dm 3 ) both have harmful effect on growth , biomass or protein content of S.platensis , but no effect on total carbohydrate content.Therefore CC can be used as an effective succedaneum of NaHCO 3 in culturing of S.platensis and lead to decrease in the cultural cost
