BIOCATALYST SOLVENT USING IONIC LIQUID, AND BIOCATALYST SOLUTION CONTAINING BIOCATALYST AND SAID SOLVENT

WIPO Patent Application WO/2015/156398

A1

　Provided are: a biocatalyst solvent that can be stored for a long period of time and that can dissolve a high concentration of a biocatalyst from low temperatures to high temperatures while retaining the activity of the biocatalyst; and a biocatalyst solution using said biocatalyst solvent.　The biocatalyst solvent comprises an ionic liquid containing anions and quaternary ammonium cations represented by formula (I). (In the formula each Ra independently represents: a hydroxyalkyl group which has at least one hydroxyl group, in which the alkyl moiety is in a C1-10 straight-chained or branched state, and in which said alkyl moiety may contain an oxygen atom; a carboxyalkyl group which has at least one carboxy group, in which the alkyl moiety is in a C1-10 straight-chained or branched state, and in which said alkyl moiety may contain an oxygen atom; or a hydroxy-carboxyalkyl group which has at least one each of a hydroxyl group and a carboxy group, in which the alkyl moiety is in a C1-10 straight-chained or branched state, and in which said alkyl moiety may contain an oxygen atom. Each Rb independently represents a hydrogen atom or a C1-5 straight-chained or branched alkyl group. n represents an integer of 1-4.)
