A novel, nearly isothermal, nonselective-membrane separation process, membrane vapor extraction (MVE), efficiently recovers butanol from a dilute aqueous solution, for example, from a fermentation broth (Liu et al., 2015). In MVE, feed and solvent liquids are not in contact; they are separated by vapor. Therefore, compared to conventional extractio...
Dissolution of lignocellulosic biomass in certain ionic liquids (ILs) can provide an effective pretreatment prior to enzymatic
saccharification of cellulose for biofuels production. Toward the goal of combining pretreatment and enzymatic hydrolysis,
we evolved enzyme variants of Talaromyces emersonii Cel7A to be more active and stable than wild-typ...
A rapid screen was developed to test the stability of proteins in ionic liquid–aqueous mixtures using green fluorescent protein (GFP) as a reporter. In at least one ionic liquid (IL), GFP retained 50% or more of its fluorescence in IL volume fractions as high as 75%. ILs that best preserved GFP fluorescence also showed the best retention of cellula...
