Applications of the BAHLM technology (Chapter 6) in metal ions, salts separation, biotechnological, and isomers separations are reviewed. Commercially available membrane modules and equipment may be used in the BOHLM and BAHLM. It should be noted that Chapters 5 and 6 may also contain relevant information for other fields.

A number of review articles " and books °" have been devoted to microemulsions. The reader should refer to these publications (and to references therein) for more information regarding aspects of these systems that are not treated in this chapter and that extend from chemical formulation to physical properties, going through theoretical aspects, applications in analytical science and separation, biotechnology, pharmacology, chemical reactivity, polymer synthesis, and so forth. 

Manufacturing approaches for selected bioproducts of the new biotechnology impact product recovery and purification. The most prevalent bioseparations method is chromatography (qv). Thus the practical tools used to initiate scaleup of process Hquid chromatographic separations starting from a minimum amount of laboratory data are given. 

Biopolymer Extraction. Research interests involving new techniques for separation of biochemicals from fermentation broth and cell culture media have increased as biotechnology has grown. Most separation methods are limited to small-scale appHcations but recendy solvent extraction has been studied as a potential technique for continuous and large-scale production and the use of two-phase aqueous systems has received increasing attention (259). A range of enzymes have favorable partition properties in a system based on a PGE—dextran—salt solution (97) ...

Nevertheless, despite the inherent disadvantages of exclusion chromatography, there are instances where it is the only practical method of choice. The technique is widely used in the separation of macro-molecules of biological origin, e.g. polypeptides, proteins, enzymes, etc. In fact, it is in this area of biotechnology where the major growth in HPLC techniques appears to be taking place. 

The Cyclobond materials are some of the most effective in separating isiomers generally and their development continues. It is likely that chiral chromatography will become increasingly important as the products from biotechnology continue to proliferate into the pharmaceutical field. 

The development of snch new separation is cracial to the development of indnstrial biotechnology.
