1 INTRODUCTIONIn biotechnology there is a need for new protein recovery process,which combines a highselectivity for the desired product with substantial concentration increased and easy to scale-up.In this context,liquid-liquid extraction with reversed micellar phase might serve this purpose.Reversed micelles are aggregates of surfactant molecules containing an inner core of water mole-cules,dispersed in a continuous organic solvent medium.These systems are opticallytransparent and thermodynamically stable.It has beendemonstrated [1,2]that under certainconditions proteins can be transferred from an aqueous phase towards a reversed micellarphase or vice versa(Fig.1)
