Abstract

我々はこれまでに、常温で液体のカルボン酸系liquid zwitterion (OE2imC3C)が「セルロース溶解能」および「低毒性」という性質を有することから、ワンポットエタノール発酵を達成した。しかし、OE2imC3Cは粘性が非常に高く、セルロースの溶解量が限られている。そこで本検討ではジメチルスルホキシド(DMSO)を共溶媒として加え、粘性の低下を試みた。その結果、より多くのセルロースを溶解できた。また、DMSOを加えることで溶液の毒性を低下させることもできた。 Ionic liquids (ILs) can dissolve cellulose efficiently. However ILs are toxic to microorganisms, because cation inserts into hydrophobic part of lipid bilayer membrane of microorganisms.1) We have developed a carboxylic acid-type of liquid zwitterion (ZI), OE2imC3C (Figure 1), which satisfy both low toxicity and dissolution of cellulose.  This advantage allows a one-pot conversion process of biomass into ethanol via pretreatment, hydrolysis, and fermentation. However, the OE2imC3C has a problem: high viscosity. In this study, a co-solvent, dimethyl sulfoxide (DMSO), was added to decrease the viscosity.
