This second edition has been thoroughly updated to include recent advances and developments in the field of fermentation technology, focusing on industrial applications. The book now covers new aspects such as recombinant DNA techniques in the improvement of industrial micro-organisms, as well as including comprehensive information on fermentation media, sterilization procedures, inocula, and fermenter design. Chapters on effluent treatment and fermentation economics are also incorporated. The text is supported by plenty of clear, informative diagrams.This book is of great interest to final year and post-graduate students of applied biology, biotechnology, microbiology, biochemical and chemical engineering.

Prior to joining the University of Hertfordshire, Allan was a research scientist with ICI, working on aspects of fungal physiology and plant tissue culture. His career as a Senior Lecturer at the University of Hertfordshire encompassed teaching in microbiology and research in microbial physiology and fermentation technology. Allan retired from the University and continued as a visiting lecturer but also combined his interests in microbiology and local history in his research into the history of brewing in Hertfordshire.Stephen's career as Senior Lecturer at The University of Hertfordshire has encompassed teaching in numerous fields across the Chemical, Biological and Environmental Sciences, together with research in effluent treatment, microbial physiology and fermentation technology. He was a member of the Society of Chemical Industry and a Fellow of the Higher Education Academy. Both Allan and Stephen have taken an advisory role in the development of this edition but the influence they had on the previous three editions very much remain as a foundation of the current book.

Selected chapter headings: An introduction to fermentation processes. Media for industrial fermentations. Sterilization. Aeration and agitation. Effluent treatment. Fermentation economics.
