We report the spontaneous formation of a stable mannitol-producing variant of Leuconostoc pseudomesenteroides. The mannitol-producing variant showed mannitol dehydrogenase activity which was absent in the parental strain. It was also able to use fructose and glucose simultaneously, whereas the parental strain showed diauxic growth with these sugars. A possible explanation of these observations is discussed.
我们报道了假肠膜明串珠菌产生甘露醇的稳定变异体的自发形成。产生甘露醇的变异体表现出亲本菌株所没有的甘露醇脱氢酶活性。它还能够同时利用果糖和葡萄糖,而亲本菌株对这些糖表现出二次生长。对这些观察结果的一种可能解释进行了讨论。
