Beschreibung
Zusammenfassung:	The invention relates generally to the field of industrial microbiology and butanol production from sources of 5-carbon sugars such as lignocellulosic hydrolysates. More specifically, the invention relates to the use of an xylulose or xylulose-5 -phosphate-producing enzyme and micro-aerobic or anaerobic conditions to increase butanol production from such sugars and recovery of said butanol through ins situ product recovery methods. L'invention concerne d'une manière générale le domaine de la microbiologie industrielle et de la production de butanol à partir de sources de sucre à 5 carbones telles que des hydrolysats lignocellulosiques. De façon plus spécifique, l'invention concerne l'utilisation d'une enzyme de production de xylulose ou de xylulose-5-biphosphate et de conditions micro-aérobies ou anaérobies pour augmenter la production du butanol à partir de sucres et la récupération dudit butanol par des méthodes de récupération de produit in situ.
