    • The present invention provides an improved method for the biological production of 1,3-propanediol from a fermentable carbon source in a single microorganism. In one aspect of the present invention, an improved process for the conversion of glucose to 1,3-propanediol is achieved by the use of an E. coli transformed with the Klebsiella pneumoniae dha regulon genes dhaR, orfY, dhaT, orfX, orfW, dhaB1, dhaB2, dhaB3, and orfZ, all these genes arranged in the same genetic organization as found in wild type Klebsiella pneumoniae. In another aspect of the present invention, an improved process for the production of 1,3-propanediol from glucose using a recombinant E. coli containing genes encoding a G3PDH, a G3P phosphatase, a dehydratase, and a dehydratase reactivation factor compared to an identical process using a recombinant E. coli containing genes encoding a G3PDH, a G3P phosphatase, a dehydratase, a dehydratase reactivation factor and a 1,3-propanediol oxidoreductase (dhaT). The dramatically improved process relies on the presence in E. coli of a gene encoding a non-specific catalytic activity sufficient to convert 3-hydroxypropionaldehyde to 1,3-propanediol.
    • 本发明提供了从单一微生物中的可发酵碳源生物制备1,3-丙二醇的改进方法。 在本发明的一个方面,通过使用用肺炎克雷伯杆菌dha调节基因dhaR或orfY,dhaT,orfX或ff转化的大肠杆菌来实现葡萄糖转化为1,3-丙二醇的改进方法, dhaB1,dhaB2,dhaB3和orfZ,所有这些基因排列在与野生型肺炎克雷伯菌中发现的相同的遗传组织中。 在本发明的另一方面,使用含有编码G3PDH,G3P磷酸酶,脱水酶和脱水酶活化因子的重组大肠杆菌从与葡萄糖生产1,3-丙二醇的改进方法相比, 使用含有编码G3PDH,G3P磷酸酶,脱水酶,脱水酶活化因子和1,3-丙二醇氧化还原酶(dhaT)的基因的重组大肠杆菌的方法。 显着改善的方法依赖于在大肠杆菌中存在编码足以将3-羟基丙醛转化成1,3-丙二醇的非特异性催化活性的基因。
