Principles of Fermentation Technology, 4th Edition

Peter served as a Principal Lecturer at the University of Hertfordshire, focusing on teaching and research in microbial physiology and fermentation technology. His professional experiences include sabbatical periods at ICI Fermentation Products, the Warren Spring Laboratory, and in the laboratory of Professor Ayaaki Ishizaki at Kyushu University, Japan. He also held significant managerial positions, including Head of Biochemistry and Microbiology and Associate Head of the School of Life Sciences. Although now retired, Peter returned as a Visiting Lecturer and was awarded a University Fellowship by the University of Hertfordshire in 2016. He is a member of the Microbiology Society, having previously served as its Treasurer and as Convener of the Fermentation Group.

Allan, prior to joining the University of Hertfordshire, was a research scientist with ICI, where his work involved fungal physiology and plant tissue culture. His academic career at the University of Hertfordshire as a Senior Lecturer involved teaching microbiology and conducting research in microbial physiology and fermentation technology. After retiring from the University, Allan continued as a visiting lecturer. He also combined his passions for microbiology and local history through his research into the history of brewing in Hertfordshire.

Stephen has had a career as a Senior Lecturer at the University of Hertfordshire, teaching across various disciplines within the Chemical, Biological, and Environmental Sciences. His research interests include 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 provided advisory support for the development of this edition. Their contributions to the previous three editions have laid a strong foundation for the current work.
