Fermentation is important in the areas of both academic and industrial research. This book is a collection of methods and techniques covering the setting up and use of fermentation units. The emphasis is on the use of small-scale fermenters and the interdisciplinary nature of fermentation itself. As well as being of widespread interest to academic researchers, this technology has many important industrial applications, as evidenced by the affiliations of the authors (Hoechst, ICI, and Beecham Pharmaceuticals).
