Bioethanol fermentation in the presence of ionic liquids: mini review
Kosuke Kuroda
Abstract:Ionic liquids are efficient pretreatment solvents for cellulosic biomass, but typical cellulose-dissolving ionic liquids are toxic to microorganisms, hindering the fermentation process for bioethanol production. Here I summarize the mechanisms of toxicity and how to overcome the toxicity.
The imidazolium/phosphate zwitterion synthesised in this study dissolved cellulose and satisfies all other properties required for efficient cellulosic bioethanol production such as liquid at room temperature and low toxicity.

We studied the pretreatment abilities of an ionic liquid and a zwitterionic liquid. The low pretreatment ability of the zwitterionic liquid evaluated was based on its high viscosity.
For extremely efficient bioethanol production, simultaneous pretreatment, saccharification, and fermentation in the same reaction pot (called one-pot process) is necessary. Thermotolerant yeast Kluyveromyces marxianus can ferment at around 50 °C...
