| titleOfInvention | Lignocellulose stepped saccharification fermentation method with polyethylene glycol-water as medium |
| abstract | The invention relates to a lignocellulose step-by-step saccharification and fermentation method with polyethylene glycol-water as a medium. The method takes pretreated lignocellulose as a substrate, takes a polyethylene glycol/water mixture as a fermentation medium, adopts a strategy of supplementing the substrate and cellulase in batches and removing solid residues of enzymolysis liquid step by step before fermentation, improves the solid content and reduces the concentration of toxic inhibitors, thereby obtaining high-concentration ethanol. The invention has the advantages that: the fed-batch process is favorable for heat transfer and mass transfer in the enzymolysis process, and hydrolysate with high-concentration reducing sugar can be obtained; solid residues generated by enzymolysis can be used as an adsorbent of fermentation toxicity inhibitors, fermentation toxic substances are effectively removed through centrifugal separation, enzymolysis liquid can be directly used for fermentation without detoxification treatment, and the polyethylene glycol can effectively relieve the inhibition of residual toxic compounds in liquid on ethanol fermentation; the obtaining of the hydrolysate of high-concentration reducing sugar can improve the concentration of ethanol produced by later fermentation, thereby reducing the production cost of the cellulosic ethanol. |
