have several bottles of ILs which we have used many times over
successively for more than ten years. We believe that further
investigation of the scope and limitations of the biochemical
reaction in ILs will make them even more beneficial.

17 M.-J. Kim et al. first reported the ionic liquid coated lipase, though
no acceleration was obtained for the enzyme because the authors
prepared it by just mixing the lipase protein with an ionic liquid: J.

25 We attempted to prepare several types of methoxy poly(ethoxy)ethyl-
substituted phosphonium ILs, however, it was found that these salts
were not appropriate as solvents because they were too viscous to
conduct the lipase-catalyzed reactions.
