The Biotechnology Annual Review covers the various developments in biotechnology in the form of comprehensive, illustrated and well referenced reviews. With the expansion of the field of biotechnology, coupled with the vast increase in the number of new journals reporting recent results in this field, the need for a publication that is continuously providing reviews is urgent. Hence, each volume of the Biotechnology Annual Review will have a number of reviews covering different aspects of biotechnology. Reviewed topics will include biotechnology applications in medicine, agriculture, marine biology, industry, bioremedation and the environment. Fundamental problems dealing with enhancing the technical knowledge encountering biotechnology utilization regardless of the field of application will be particularly emphasized. This series will help both students and teachers, researchers as well as administrators to remain knowledgeable on all relevant issues in biotechnology.

Biotechnology is a diverse, complex and rapidly evolving field. Students and experienced researchers alike face the challenges of staying on top of developments in their field of specialty and maintaining a broader overview of the field as a whole. Volumes containing competent reviews on a diverse range of topics in the field fulfill the dual role of broadening and updating biotechnologists knowledge. The current volume is an excellent example of such a book. The topics covered range from classical issues in biotechnology - such as, vehicles for the production of biotechnology products and methods for their detection, separation and analysis - to topics that are focused on the role of biotechnology in the health sciences. The information presented in this book will therefore will be of great value to both experienced biotechnologists and biotechnologists in training.
