氯化胆碱在钝顶螺旋藻(Spirulina platensis)养殖中的应用初探

Spirulina platensis was grown in Zarrouk′s meida with low NaHCO3 content (5～2 g/dm3), 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/dm3 NaHCO3 with 10.0 mg/dm3 CC ; biomass, protein and total carbohydrate contents were also increased to some extent. Low concentration of NaHCO3 (<4 g/dm3 ) or high concentration of CC(>10.0 g/dm3 ) 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 NaHCO3 in culturing of S.platensis and lead to decrease in the cultural cost.
