Abstract

Currently, the use of enzymes as efficient tools for the preparation of highly valuable molecules in various industries has proven to be a tremendous development. The preparation of esters via biotechnological processes constitutes an important eco-friendly approach for several industries, especially in the field of flavour and fragrances. This is particularly due to the accrued customer’s interest in products labelled as natural ensured by using enzymes as natural catalysts. This mini-review article is dedicated to underline the recent advances (from 2010 to 2022) in the bio-acylation of achiral and chiral alcohols (esterification and transesterification). The preparation conditions, such as enzyme nature, acyl donor, solvents, etc., are highlighted.
