Clostridium bacteria modified to assimilate several sugars simultaneously, preparation and uses thereof

Abstract

The present invention relates to the genetic modification of bacteria of the genus Clostridium, typically solventogenic bacteria of the genus Clostridium. The invention also relates to methods, tools and kits enabling the elimination or modification of sequence(s) encoding, or controlling the transcription of sequence(s) encoding, the transcriptional repressors XylR and/or AraR, to the genetically modified bacteria obtained and to uses thereof, in particular for simultaneously fermenting at least one hexose and one pentose or the carbon-based elements of a substrate comprising at least two carbon-based elements chosen from glucose, arabinose, xylose, mannose and galactose.
