Abstract
A novel thermophilic and butanogenic Thermoanaerobacterium thermosaccharolyticum M5 was successfully isolated and characterized, which could produce butanol from hemicellulose via a unique ethanol–butanol (EB) pathway through consolidated bioprocessing (CBP). This represents the first wild-type bacterium which could produce butanol from hemicellulose via CBP under thermophilic conditions. The assembled draft genome of strain M5 is 2.64 Mp, which contains 2638 genes and 2465 protein-coding sequences with 33.90% G + C content. Among these annotated proteins, xylanases, xylosidases, and bifunctional alcohol/aldehyde dehydrogenase (AdhE) play key roles in the achievement of EB production from hemicellulose through CBP.
