摘要
纤维堆囊菌 (SorangiumcellulosumNUST 0 6 )产生一种胞外多糖絮凝剂 .用乙醇沉淀和Sepharose 4B凝胶层析纯化得到纯品SC 0 6 ,通过气相色谱和红外光谱分析 ,SC0 6由葡萄糖、甘露糖和葡萄糖醛酸组成 ,其比例约为 5∶3∶1 .SC 0 6的絮凝活性依赖于阳离子的存在 ,在pH2— 9范围内絮凝活性稳定 .
An exopolysaccharide flocculant ant was produced by Sorangium cellulosum NUST06.The purified SC06 can prepared by alcohol precipitation and Sepharose 4B gel chromatography.SC06 flocculant was composed of glucose,mannose and glucuronic acid with a relative proportion of 5∶3∶1 by analysis of gas chromatography and ultra-red absorption spectrometry.The flocculating activity was dependence on ion cation,and stable in the range of pH 2-9
