Abstract:
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.
