摘要 极大螺旋藻胞内和胞外多糖的含量与培养条件有关。在营养盐中 ,Na HCO3和 Na NO3浓度减少 ,胞内多糖含量也减少。硝酸钠浓度减少还使胞外多糖含量增加 ;K2 HPO4 和 Na Cl浓度变化对藻的胞内和胞外多糖含量也有影响。培养液的 p H维持在 8.0和培养 9d后的藻的胞内和胞外多糖含量均最高。 This study revealed that the content of intra and extracellular polysaccharides may be related to the cultural conditions.With decreasing NaHCO 3 or NaNO 3 concentration,the content of intracellular polysaccharide was reduced,Reduction of NaNO 3 concentration still caused the rise of extracellular polysaccharides.The K 2HPO 4 or NaCl concentration also had an effect on the production of both intracellular and extracellular polysaccharides.When PH value of media maintained at 8.0,there was the highest content of intra and extracellular polysaccharides.The same high content also occurred after culture of nine days.In addition the content of intracellular polysaccharide was higher under continuous light than under the light/dark circle.
