Abstract

The invention relates to a recombinant coryneform bacterium which secretes an organic chemical compound and in which the sugR gene which codes for a polypeptide having the activity of an SugR regulator has been attenuated. The invention further relates to a processes for using this bacterium for the fermentative preparation of organic chemical compounds.
