    • The object is to develop a bacterium capable of fermenting glucose, mannose and xylose simultaneously, which can ferment a saccharified solution of a cellulose-type or lignocellulose-type biomass resource to produce ethanol, and to construct an energy-saving high-efficiency bioethanol conversion process. Thus, disclosed is Zymomonas mobilis bacterium which is prepared by integrating a gene encoding a phosphomannose isomerase derived from Escharichia coli into a levansucrase gene located on the chromosome by the double cross-over by means of a homologous recombsination method, and then introducing recombinant DNA prepared by binding a DNA fragment containing genes encoding a xylose isomerase, a xylulokinase, a transaldolase and a transketolase, respectively, all derived from Escherichia coli to a vector. Also disclosed is a method for producing ethanol by continuously fermenting a saccharified solution of a cellulose-type biomass resource in a system on which the Zymomonas mobilis bacterium is immobilized.
    • 目的是开发能够同时发酵葡萄糖,甘露糖和木糖的细菌,其可以发酵纤维素型或木质纤维素型生物质资源的糖化溶液以产生乙醇,并构建节能高效生物乙醇转化 处理。 因此,所公开的是运动发酵单胞菌细菌,其通过利用同源重组方法将编码来自大肠杆菌的磷酸甘露糖异构酶的基因整合到位于染色体上的左旋糖蔗糖酶基因中,然后引入重组DNA 通过将分别来自大肠杆菌的编码木糖异构酶,木酮糖激酶,转醛醇酶和转酮酶的基因的DNA片段与载体结合。 还公开了通过在固定有运动发酵单胞菌细菌的系统中连续发酵纤维素型生物质资源的糖化溶液来生产乙醇的方法。
