|Resumo:||Reversed micelles are at the present time faced as common organic media to perform biocatalysis. They have been associated to the idea of a microreactor where the enzyme can be sheltered and protected from solvent detrimental effects. This simplistic idea led some investigators to ignore some basic understanding, such as the recognition of the enzyme-specific microenvironment and what the enzyme experiences inside the reversed micelle. To date the number of reactions catalyzed by lipases in reversed micelles is large. This review aims to highlight some of the fundamental aspects of the lipase microencapsulation as well as to resume the outstanding progress of the reversed micellar systems. The properties of the micellar microenvironment are reviewed and related to the lipases' performance both in terms of activity and stability. The heterogeneity of reversed micellar systems is discussed in relation to component distribution models and also to enzymatic kinetics. The new trends and the practical aspects where efforts should be centralized in order to spread out the micellar bioreactor technology over industrial processes are also discussed.
