Biomass fermenting microorganism that has been transformed genetically reductase activity was increased at the same time and reduction potential

摘要

Used in biotechnology to enhance the properties of microorganisms so that more efficiently, to produce Seisan-butsu industrially useful from fermentable sugars derived from biomass, the present invention relates to the genetic engineering of the producing microorganisms. Engineered microorganism was functionally linked to reduction and oxidation of the substrate by dehydrogenases that need the (NAD / NADH) pyridine nucleotide is simultaneously improve the reduction potential activity with the movement of electrons. In particular, increase the production of ethanol, the present invention relates to the construction of an excisable gene expression cassette for the expression of different dehydrogenases two.
