A highly efficient biocatalytic process for biodiesel synthesis in 1-methyl-3-octadecylimidazolium bis(trifluoromethylsulfonyl)imide is shown. This ionic liquid (IL) is able to dissolve triolein/methanol mixtures in many proportions, providing an homogeneous monophasic media suitable for the enzymatic synthesis of biodiesel (up to 96 % yield in 6 h at 60 °C). The enzyme/IL system can be reused for seven operation cycles without any loss in IL phase or enzyme activity.
