METHOD OF PRODUCING ETHANOL BY DIRECT OR INDIRECT FERMENTATION OF BIOMASS WITH CLOSTRIDIUM CARBOXIDIVORANS

摘要

A novel clostridia bacterial species (Clostridium carboxidivorans, ATCC BAA-624,"P7") is provided. P7 is capable of synthesizing, from waste gases, productswhich are usefulas biofuel. In particular, P7 can convert CO to ethanol. Thus, this novelbacterium cantransform waste gases (e.g. syngas and refinery wastes) into useful products.P7 alsocatalyzes the production of acetate and butanol. Further, P7 is also capableof directlyfermenting lignocellulosic materials to produce ethanol and other substances.
