1. Liquid-liquid extraction of clavulanic acid employing two-phase aqueous mixed micellar systems / Extração líquido-líquido de ácido clavulânico empregando sistemas micelares mistos de duas fases aquosas
O ácido clavulânico é um potente inibidor de β-lactamases utilizado como terapêutico em associação à amoxicilina. O processo industrial de obtenção envolve o cultivo bacteriano em processo descontínuo, enquanto que a sua purificação é realizada, principalmente, por processos de extração líquido-líquido com solventes orgânicos e etapas

2. Two-phase aqueous micellar systems: an alternative method for protein purification
Two-phase aqueous micellar systems can be exploited in separation science for the extraction/purification of desired biomolecules. This article reviews recent experimental and theoretical work by Blankschtein and co-workers on the use of two-phase aqueous micellar systems for the separation of hydrophilic proteins. The experimental partitioning behavior of t

3. Partitioning of octyl glucoside between octyl glucoside/phosphatidylcholine mixed aggregates and aqueous media as studied by isothermal titration calorimetry.
Stepwise dilution of lipid-surfactant mixed micelles first results in extraction of surfactant from the mixed micelles into the aqueous medium. Subsequently mixed micelles transform into vesicles, within a range of compositions that corresponds to equilibrium coexistence between these two types of aggregates. Further dilution results in extraction of surfact
