ABSTRACT:
The present invention provides a process for highly efficiently producing ethanol at a high productivity consisting of using a coryneform bacterium which has been transformed by a DNA containing a gene expressing pyruvate decarboxylase activity and, if desired, a gene expressing alcohol dehydrogenase activity under a regulatory sequence allowing for the expression, under ethanol production conditions wherein this bacterium does not substantially proliferate to produce ethanol.
