Metabolic engineering of a pentose metabolism pathway in ethanologenic Zymomonas mobilis

摘要: The ethanol-producing bacterium Zymomonas mobilis was metabolically engineered to broaden its range of fermentable substrates include the pentose sugar xylose. Two operons encoding xylose assimilation and phosphate pathway enzymes were constructed transformed into Z. in order generate a strain that grew on efficiently fermented it ethanol. Thus, anaerobic fermentation ethanol achieved through combination Entner-Doudoroff pathways. Furthermore, this both glucose xylose, which is essential for economical conversion lignocellulosic biomass
