“…Moreover, those ILs containing PF 6 -and TF 2 N -are more suitable for the enzymatic transesterification. Similar effects were also found in other enzymatic reactions (Katsoura et al, 2009;Pang et al, 2013). OF all tested ILs, EMIMPF 6 exhibited the highest yield (67.40 ± 2.60%) of FMAGs and FDAGs.…”

“…The synthesis methods tested include esterification and transesterification, the latter having higher reaction efficiency than the former. As we have reported earlier [11], the use of MC as a substrate during the synthesis of propyl caffeate (PC) significantly improves the yield. Thus, biosynthesis of MC could provide greener avenue for the production of the much needed MC to be used in such process.…”

“…phenolics) and nonpolar (a long chain alcohol, for example) will have both high solubility and where the enzymes maintain a good activity (Figueroa-Espinoza and Villeneuve, 2005). Nevertheless, there are some reports dealing with esterification of phenolic acids with fatty alcohols in organic solvents, solvent-free conditions (the role of which was ensured by the excess of alcohol) or in IL (Pang et al, 2013;Weitkamp et al, 2006;Yang et al, 2012). According to these studies, the lipase-catalyzed reactions in organic solvents are preferable and a binary mixture of solvents seems to be the best solution to achieve this kind of reaction since it allows to finely tune both the solubility of the substrates and the lipase's activity/stability.…”

-With the recent interest on green chemistry, the scientists have focused on developing new and more efficient solvents to carry out enzymatic-catalyzed reactions with emphasis on reduced costs, risks and toxicity while improving biodegradability. Among the new available solvents, the multimolecular-based liquids (such as ionic liquids and eutectic solvents) have been the subject of most recent studies. Currently, and mainly due to its environmental and economic features, DES are arousing much interest and curiosity. Regarding the biotransformations with lipases, the so-called "lipophilization" reactions are of major interest. However, they are complex to implement mainly because it is difficult to find a suitable reaction medium. Thus, this review aimed at providing a presentation of these multimolecularbased solvents with general overview of the recent studies dealing with lipase-catalyzed reactions in DES. In addition, emphasis was placed on their strengths and weaknesses, especially with the perspective to be use as efficient and green medium to implement complex and valuable biotransformation such as lipase-catalyzed lipophilizations.Keywords: Low transition temperature mixtures / deep eutectic solvents / Lipase / Lipophilization Résumé -Solvants de type eutectiques profonds : milieux réactionnels adaptés aux réactions de lipophilisation biocatalysées par les lipases ? Depuis le début des années 1990 et l'émergence de la « chimie verte », il est indispensable de concevoir des nouveaux procédés, en particulier enzymatiques, qui mettent l'accent sur la réduction des coûts, des risques et de la toxicité tout en améliorant la biodégradabilité. Les nouveaux solvants de type « liquides multimoléculaires » (tels que les liquides ioniques et les solvants eutectiques) ont fait l'objet de la plupart des études récentes. Actuellement, et principalement en raison de ses atouts environnementaux et économiques, les solvants eutectiques suscitent beaucoup plus d'intérêt et de curiosité. Concernant les biotransformations lipasiques, les réactions dites « de lipophilisation » présentent de nombreux avantages. Cependant, ces réactions sont complexes à mettre en oeuvre, principalement parce qu'il est difficile de trouver un milieu réactionnel adapté. Ainsi, cette revue a pour objectif de fournir une présentation de ces milieux réactionnels avec un aperçu des travaux récents portant sur les réactions lipasiques dans des solvants eutectiques. En outre, l'accent a été mis sur leurs forces et leurs faiblesses, avec la perspective d'être utilisés comme milieu réactionnel « vert » pour mettre en oeuvre des biotransformations complexes telles que les réactions de lipophilisation biocatalysées par les lipases.
