| 摘 要： | 胶德克斯氏菌周毛变种7954菌株所产生的胞外多糖是一种粘度很高的水溶性物质,其水溶液具有良好的流变特性,为典型的假塑性流体。其粘度随浓度增加而增大,在50～75℃加热处理的温度范围内,其粘度随温度升高而增大,耐酸碱能力强,但耐盐力差。

| Abstract: | The extracellular polysaccharide extracted from Derxia gummosa var. peritricha strain 7954 was a matter of water solubility with high viscosity. The aqueous solution was a typical pseudoplastic fluid which possessed a good rheological property. It was quite stable under heating treatment. The viscosity could not be affected by pH value when it was altered between 3-12, but decreased rapidly with increasing the concentration of various salts. |
