Abstract
This invention comprises a process for the bioconversion of a fermentable carbon source to n-butanol by a microorganism, wherein the microorganism is deficient in at least one gene or protein involved in the four-carbon compounds pathway regulation to improve the four-carbon compounds pathway, particularly by inactivation of the transcriptional repressor rex.
Claims12
A method for the production of n-butanol comprising culturing a modified microorganism of a Clostridium species in an appropriate culture medium comprising a source of carbon, wherein said modified microorganism has at least the gene rex encoding a redox-sensing transcriptional repressor recombinantly inactivated or deleted.
A microorganism of Clostridium species, useful for the production of n-butanol from a carbon source, wherein said microorganism comprises recombinant inactivation or deletion of the gene rex.
