The study deals with nanofiltration for separating saccharides from phenolics and considers permeation of each individual sugar (mono- or disaccharide) from a plant hydrolysate compared to a model sugar solution. Experiments are carried out in a cros

Room-temperature ionic liquids (ILs) represent molten salts entirely consisting of ions, usually a charge-stabilized organic cation and an inorganic or organic anion. ILs are liquids at ambient temperature but possess characteristics unusual for the

This study considers the effect of cross-flow velocity and transmembrane pressure on flux and rejection behavior during nanofiltration of Eurasian water milfoil hydrolysate. Fractionation by nanofiltration was applied to obtain a glucose-rich permeat

Controlled partitioning of a commercial α-amylase is achieved in aqueous biphasic system (ABS) of a hydrophobic and polar ionic liquid, 3-methyl-1-octylimidazol-3-ium saccharinate ([C8C1im][Sac]). Studying the effects of pH and [C8C1im][Sac]-concent

In this work, separation of poly- and disaccharides is achieved by means of novel biphasic systems based on ionic liquids as alternative to the volatile organic compounds used in large amounts for precipitation of the polysaccharides produced from di
