This book focuses on in vitro techniques and challenges of producing nutraceutical compounds from plant cells. In addition, it provides an overview of different biosynthesis pathways and their modulation through cell culture techniques for the production of nutraceutical compounds in high quantity and quality. It also includes the assessment of the factors influencing production and advances in cell culture techniques, including the scale-up approach using bioreactors. Lastly it provides valuable suggestion for future research.

Dr. Tarun Belwal, working at the College of Biosystems Engineering and Food Science, Zhejiang University, China, is exploring food science, plant nutraceutical potential, and human health, including the effect of food bioprocess techniques on its quality and other functional attributes. He is currently engaged in the development and promotion of safer and greener postharvest food bioprocess techniques, in vitro cell culture techniques, nano-technologies, extraction and separation techniques. Dr. Belwal received his Ph.D. (Plant Biotechnology) from Kumaun University in collaboration with G.B. Pant National Institute of Himalayan Environment and Sustainable Development, India. Prior to moving to ZJU, he has worked on the utilization of natural products as nutraceutical agents and examined its functional activities, development of in vitro cell culture and production of secondary metabolites and advanced extraction protocols, for which he has awarded by the prestigious 'Governor award for Best Research' by the Government of India, consequently for two years. He edited one book, published 50+ international research peer-reviewed articles and 7 book chapters. His total IF is more than 270, with citations more than 600. He is actively engaged as reviewer for several prestigious journals, named few as Food Chemistry, Industrial Crops & Products, Food Reviews International, Food Research International, Journal of Agriculture and Food Chemistry, Pharmacological Research, Bioresource Technology, Preparative Biochemistry and Biotechnology, South African Journal of Botany, Microbial Pathogenesis, and Journal of Biomolecular Structure & Dynamics. He has won several awards and also secure China Postdoctoral Science Foundation research grant as Project Investigator. He is an active member of European Society of Sonochemistry. He has a 10 years of research experience in nutraceutical research. His research interest lies in the design and development of various bioprocess techniques (including cell culture techniques) for the efficient utilization of natural resources. Further his research interests include nanotechnology, analytical systems, ultrasonic sonochemistry, design and development of scale-up bioprocess, and nutraceuticals for health use. Dr. Milen I. Georgiev holds a PhD in Biotechnology from the Stephan Angeloff Institute of Microbiology (Bulgarian Academy of Sciences). He has 18 years of experience in natural products field and has published in excess of 150 papers, which attracted 2500+ citations. He has delivered 50+ invited lectures in 20 different countries (incl. USA, Germany, The Netherlands, China, ROC Taiwan, Thailand, Greece, Serbia, Romania, Poland).Milen holds several grants from the NSF of Bulgaria and framework programs of the European Union (incl. H2020 - PlantaSYST project, well-funded with 30 million Euro). At present he coordinates the SUSMAPWaste project @ USAMV Bucharest (Romania), funded with 2 million euro. In 2011 and 2015 he was awarded by the Bulgarian Government with Pythagoras award for outstanding scientist, besides "Marin Drinov" award (2009) and highly cited paper award (2018) of the Bulgarian Academy of Sciences. Dr. Georgiev serves as an Associate Editor of Phytomedicine and Food and Chemical Toxicology (both published by Elsevier), and on the Editorial boards of Biotechnology Letters (Springer Nature), Chinese Medicine (Springer Nature) and Molecules (MDPI), also prepared 10 Guest Editorials for major journals on biotechnology and natural products fields. Serving as a chairman he established the International Conference on Natural Products Utilization: from Plants to Pharmacy Shelf (ICNPU), which had four issues so far. The latest ICNPU edition attracted attention of 330+ participants from 50 different countries (www.icnpu.com/2019). His current research focuses on the biosynthesis
