| Abstract: | The studies on the method of extraction and purification of the extracellular polysaccharide from Derxia peritricha revealed that the optimum cultural duration is 30±2 hours for producing the polysaccharide. The biomass can be removed by means of centrifugation in the condition of the viscosity between 6.77-9.27 Pa·s. The amount of alcohol used for purification can be decreased 3/5 with adding 1×10-2 NaCl. The result of component analysis by the method of HPLC demonstrated that this extracellular polysaccharide contains rhamnose, xylose, glucose, mannose, arabinose, fructose and two other unidentified monosaccharides. |
