The Draft Genome Sequence of Clostridium beijerinckii NJP7, a Unique Bacterium Capable of Producing Isopropanol–Butanol from Hemicellulose Through Consolidated Bioprocessing

Abstract

A wild type solventogenic Clostridium beijerinckii NJP7 capable of converting polysaccharides, such as hemicellulose, into butanol and isopropanol via a unique acetone–isopropanol–butanol (AIB) pathway was isolated and characterized. This represents the first wild type isopropanol–butanol generating bacterium which could achieve butanol production directly from lignocellulose through consolidated bioprocessing (CBP). Strain NJP7 was isolated from decomposite soil from Laoshan Nature Park, China, and its genome shows 98.6% identical to 89.5% of the Clostridium diolis submitted genome sequence. The assembled draft genome contains 5.76 Mb and 5101 predicted encoding proteins with a GC content of 29.73%. Among these annotated proteins, hemicellulase and the secondary alcohol dehydrogenase play key roles in achievement of AIB production from hemicellulose through CBP.
