About this eBook
PREFACE TO THE FIFTH EDITION I feel pleasure in bringing out the thoroughly revised, corrected and condensed edition of A Textbook of Biotechnology. Hopefully this edition will be useful for all University College students where biotechnology is being taught at Undergraduate levels. It will also be useful to all those students who are preparing for civil and various competitive examinations. Due to expanding horizon of biotechnology, it was difficult to accommodate the current information of biotechnology in detail. Therefore, a separate book entitled Advanced Biotechnology has been written for the Postgraduate students of Indian University and Colleges. Therefore, the present form of A Textbook of Biotechnology is totally useful for undergraduate students. A separate section of Probiotics has been added in Chapter 18. Chapter 27 on Experiments on Biotechnology has been deleted from the book because most of the experiments have been written in Practical Microbiology by R.C. Dubey and D.K. Maheshwari. Bibliography has been added to help the students for further consultation of resource materials. I am thankful to the management and the editorial team of S. Chand Company Pvt. Ltd. for all help and support in the publication of this book. Reader s perception in the form of constructive suggestions and valuable comments for improvement of this book is highly appreciated.

PREFACE TO THE FIRST EDITION
ecently, biotechnology has been introduced in syllabi of most of the universities, at the under graduate and or postgraduate level s , either as a separate paper or a part of it. The author has been teaching biotechnology for the last two years and realises the problems of students. Therefore, this book is compiled to provide the students, the current informations on different areas of biotechnology. The author does not claim this as his original research work. It is merely an outcome of the compilation of researches done by the scientists in different areas of biotechnology in India and abroad. Help has been taken from a number of standard books, journals, research and review papers to update the knowledge. This book embodies five different parts, divided in seventeen chapters. The language of the text is simple and the subject matter is fully illustrated. Some of the figures have been drawn by the author himself. Sources of such figures and tables that are modified and presented in the text, are duly acknowledged in their legends. At the end of each chapter, some relevant problems are given which would help the students to grasp the matter. A short reference of the source materials and the subject- index are listed at the end of the book. In the references, the title of each paper is omitted just to save the space in this elementary book.
