【摘要】 用以新华滤纸为唯一碳源的选择培养基从土壤中初筛到12株产纤维素酶且生长旺盛的细菌,采用刚果红鉴别培养基作进一步识别,获得透明圈较大的菌株5株。在此基础上,进行液体培养,测定酶活,并对其进行了部分鉴定。通过Y2菌降解细江蓠细胞壁的试验表明Y2菌具有一定的应用价值。更多还原

【Abstract】 12 cellulose-decomposing bacteria were isolated from soil by selective liquid medium with xinhua filter paper sole carbon source.Five colonies had been gotton by screening some colonies which were surrounded by some distinct zones of clearing in cellulose-congo red agar medium.By measuring the enzyme activity of liquid culture filtrates,some strains,with higher cellulase activity,had been found.The experiment that decomposing Gracilaria te-nuispitata var.Liui walls by Y2 showed that Y2 has the utilization value to some extent.更多还原
