Biochemical engineering forms a bridge between fundamental biochemical research and large scale biotechnology processes. It covers genetic and protein engineering, cell culture, bioprocess and reactor design, separation and modelling. Research work in biochemical engineering is an investment in the future, when conventional resources will have to be replaced with renewable ones. In this book the papers presented at the Asia-Pacific Biochemical Engineering Conference (Yokohama, Japan 1992) are collected. This collection is unique in its wide coverage of topics and it gives an overview of the current trends of research in an important area.
