Abstract:
The present invention relates to a transformed strain having ethanol production potential, constructed by introducing a foreign gene for ethanol production into a non-ethanol producing acetogen Eubacterium limosum and a method for producing ethanol, using the strain. According to the present invention, Eubacterium limosum which is a conventional acetogen lacking ethanol production potential is used to produce ethanol, which is a high value-added product, as a single product from carbon monoxide contained in waste gas.
