| 摘 要： | 以肌苷产生菌B3为出发菌株，通过硫酸二乙酯，紫外线及原生质体紫外线等复合诱变处理，获得一株核糖高产积累突变株B1916，对突变株B1916遗传进行了研究，结果发现该突变株对碳水化合物的利用能力发生了变化，如对葡萄糖利用能力下降，不能利用阿拉伯糖和葡萄糖酸，丧失了解子形成能力；在培养过程中细胞形态呈链状，数字状等。

| Abstract: | The inosine producing strain B3 was selected as the parent strain. Mutant B1916 with high D-ribose-producing ability was isolated by united mutagenic treatment of DES, uvradiation and protoplast treated by UV-way. Mutant B1916 could not grow on such carbohydrates as D-gluconic acid, L-arabinose as exclusive carbon sources, and the ability of utilizing glucose was decrease. It was defective of spore formation. Mutant B1916 formed chains and number during growth process. |
