摘要 |
The invention relates to a microorganism strain and a method for the fermentative production of C4 compounds from C5 sugars (pentoses). The microorganism strain of the genus Raoultella, Klebesiella, Bacillus or Paenibacillus containing a poxB gene is characterized in that the poxB gene is inactivated and in that the sugar in a lignocellulosic biomass is a pentose obtained from hemicellulose. |
