"There is an increased demand for plant based compounds and biotechnological approaches have potential to meet this challenge. This book provides a comprehensive account of such approaches. This book comprises topics like secondary metabolite production in culture using different approaches such as optimization, selection, biotransformation and possible mechanism of production, genetic transformation for production and use of different types of bioreactor systems. Diverse compounds such as alkaloids, steroids, insecticides, anti-tumour agents and colours and flavours etc. are arranged in different chapters. Various techniques to study cell cultures for the production of secondary metabolites and some class room exercises are also included
