| 摘 要： | 野外采样分离筛选得到一株热凝多糖产生菌ＱＬ１０９菌株，该菌株非粪产碱菌（Ａｌｃａｌｉｇｅｎｅｓｆａｅｃａｌｉｓｖａｒ．ｍｙｘｏｇｅｎｅｓ）．经摇瓶发酵得到ＱＬ１０９菌株产生的多糖，该多糖经红外光谱等的初步分析，结果表明：ＱＬ１０９菌株产生的多糖与ＳＩＧＭＡ公司的标准品热凝多糖（Ｃｕｒｄｌａｎ）结果一致，证明ＱＬ１０９菌株是热凝多糖产生菌．进一步的实验证明，该菌株所产生的热凝多糖具有良好的流变学性质．

| Abstract: | The strain QL109 producing curdlan was isolated from wildness soil.Owingto its all charcterizations,it is considered not to belong to Alcaligenes faecalis Var.myxogenes.By shaking cultivation,we obtained one kind of extracellular polysaccharideyielded by strain QL109,which is considered identical to the curdlan sample of SIGMA Chemical Co.by IR spectrum.It was proofed that the strain QL109 is producer of curdlan.Meanwhile,we found that the Curdlan of the strain QL109 has an excellent characterization of rheology. |

| Keywords: | Curdlan producer of curdlan vicosity characterization of rheology |
