Abstract

original image

Stimulating the hunger of enzymes: The design of an ionic liquid that has the ability to dissolve cellulose has been attempted from the viewpoint of a cellulase. N,N-diethyl-N-(2-methoxyethyl)-N-methylammonium alanine ([N221ME][Ala]) is a good solvent for cellulose. Dissolution in [N221ME][Ala] converts the crystalline structure of cellulose from Type I to II, which is known to be a form easily digested by cellulases.
