| 摘 要： | 用N-甲基-N′-硝基-N-亚硝基胍(NTG)对兽疫链球菌进行诱变,获得高产菌株.经过对该菌株的发酵培养,将产生的多糖经Savage法、季铵复合物沉淀法、DEAE-纤维素(DE52)离子交换层析法及SephadexG-75凝胶过滤法分离纯化.纯化的多糖结构经化学组成分析、核磁共振波谱、红外光谱及圆二色谱鉴定,证明了诱变得到的高产菌株(StreptococcuszooepidemicusJ18)再经发酵,得到的多糖为透明质酸.通过刚果红实验证明了透明质酸的构象为单股螺旋结构,其平均分子量约为1.16×106.

| Abstract: | A mutated strain of Streptococcus zooepidemicus capable of producing the polysaccharide in a high yield was obtained after being mutated bythe chemical agent N-methyl-N′-nitro-N- nitrosoguanidine(NTG). Polysaccharide produced bythe mutated strain of Streptococcus zooepidemicus was purified bythe procedure including Savage method, quaternary ammonium compound precipitation, DEAE-cellulose(DE52) column chromatograph and Sephadex G-75 gel filtration. The purified polysaccharide was proved to be hyaluronic acid(HA) by means of chemical composition analysis, 13C NMR, Infrared spectra, and circular dichroism. The single helix conformation of the purified HA was studied by Congo red experiment. The molecular weight of the HA was about 1.16×106, which was measured by viscosity method. |
