The bioseparation engineering of today includes downstream process engineering such as waste water, material and gas treatment. Taking this tendency into account, bioseparation engineers gathered in Japan as a special research group under the main theme of "Recovery and Recycle of Resources to Protect the Global Environment". The scope of this book is based on the conference, and deals not only with recent advances in bioseparation engineering in a narrow sence, but also the environmental engineering which includes waste water treatment and bioremediation. The contributors of this book cover many disciplines such as chemical engineering, analytical chemistry, biochemistry, and microbiology. Bioseparation Engineering will stimulate young engineers and scientists who will develop bioseparation engineering further in the 21st century, and contribute to a world-wide attention to the global environment

Success in meeting the challenge to produce the commercial products anticipated by the exploitation of biological processes depends upon provid ing effective separation protocols. Effectiveness can be measured in terms of selectivity, purity, resolution and validatory success. The major processing problems are associated with either the selective recovery of molecules which are present in low concentrations from complex mixtures or the selective removal of contaminants from the desired molecule. Central to the evolution of processes satisfying this demand are the regulatory requirements being imposed by governments on the purity of a product, especially in the health care market. Synthetic organic chemists are increasingly finding it advantageous to conduct one or more steps using either enzymic biotransformations where molecules with a single and consistent stereochemistry or chirality are required. The underlying princi ples behind the methods, techniques and processes currently being used and developed commercially rely upon the biospecific nature and properties of the desired molecule. When these factors are married to the more traditional techniques of precipitation, chromatography, liquid-liquid extraction and membrane processes, powerful tools emerge, allowing highly selective separations to be designed. The logical extension of these combinations is to apply genetic engineering techniques to influence the separations at a more fundamental and structural level by modifying the target protein at source, during its synthesis, to facilitate its separation in a given, selective manner, leading to the distinct possibility of producing 'designer' separation programmes.
