Abstract
The use of a combination of—at least one ionic liquid which is lipophilic, and non miscible with water, and—at least one enzyme, for the implementation of an esterification and/or transesterification process of a substrate with at least one alcohol, the substrate consisting of oils, fats, fatty acids, or a mixture thereof, wherein the ionic liquid, the substrate, and the alcohol form a single homogeneous liquid phase at the temperature at which the esterification and/or transesterification process is performed.
