Abstract
The growth of strain araC(c)67, which produces the enzymes of the ara operon constitutively, is inhibited by the addition of ribitol. Isolation of strains resistant to ribitol yields mutants of either the araB or araC genes. A model to account for the inhibition by ribitol is discussed.
摘要
持续产生阿拉伯糖操纵子酶的菌株araC(c)67的生长会受到核糖醇添加的抑制。分离出对核糖醇具有抗性的菌株，可得到araB或araC基因的突变体。文中讨论了一个解释核糖醇抑制作用的模型。
