TL;DR: In this article, a multicomponent, non-linear model that takes into account the dissociation reaction in liquid phase is used to predict the separation and to investigate the effect of the resin type on the performance of parametric pumping.
13 citations
TL;DR: In this paper, a special type of adsorptive parametric pumping called temperature-swing chromatography is experimentally investigated for a new application: the separation of amino acids, and a multicomponent equilibrium model has been used to simulate the experimental results and investigate some possible ways to improve the separation.
11 citations
TL;DR: In this article, the effect of the initial concentration on the performance of parametric pumping was found to be significant, and it was shown that products with constant composition can be obtained with the help of hot regeneration.
10 citations
TL;DR: It is shown that it is always possible to concentrate the amino acids and to separate some of them under certain conditions and to investigate the effect of chloride concentration over a wide range.

TL;DR: Ion exchange parametric pumping as a cleaner separation method for producing amino acids is theoretically and experimentally investigated in this paper, where the separation of ion exchange equilibrium is parameter dependent, and owing to the electroneutrality ion exchange parameteretric pumping always separates the components.

TL;DR: The ability of mixed ionic-nonionic reverse micelles to provide a safe microenvironment for antibiotics by maintaining the strength of attraction between the reverse micelle molecule and the antibiotic while avoiding the denaturation of the antibiotic is discussed.
Abstract: This article discusses the application of mixed reverse micelles in downstream processing of antibiotics. Purification and recovery processes for antibiotics in downstream processing are major expenses, about 70% of the total cost of production, giving them a significant impact on manufacturing cost. Moreover, there are a number of challenges and difficulties in the separation process requirements for antibiotics, since the mixture is quite complex, with broth, hazardous solvents, by-products, intermediate material, and impurities; in addition, antibiotics are easy to denature. Therefore, the development of effective separation techniques is required to produce high-purity of biomaterials. The use of reverse micelles is thought to be among the most promising due to the process's high selectivity and efficiency. Most studies on reverse micelle extraction technology have been performed by using anionic surfactant sodium bis (2-ethyl-1-hexyl) sulfosuccinate (AOT). However, the activities of antibiotics hoste...
