The use of Reverse Micelles in Downstream Processing of Biotechnological   Products
  This paper aims to discuss the use of reverse micelles in downstream processing of biotechnological products. The interest in this technology is piqued firstly by various advantages of a liquid-liquid extraction process, among which are cost effectiveness, and ease of scaling up and implementing a continuous process for whole broth processing. The use of reverse micelles is thought to be among the most promising due to the high efficiency and selectivity being achieved in some systems. However, there are various issues that have impeded the widespread use of reverse micelles such as the identification and development of suitable surfactants and ligands; as well as difficulties in the back extraction process. These issues, as well as latest developments and applications of reverse micelles in downstream processing of biotechnological products will be discussed in this paper.
