  • Preface Plants are a source of secondary metabolites which are used in the production of economically viable products such as pharmaceuticals, pesticides, flavors, fragnances and pigments. Plant cell and tissue cultures can provide an alternative production system to traditional cultivation methods and chemical synthesis. The best candidates are those of high value, low volume product which cannot be produced by microbial processes and which are too complex for chemical synthesis to be a reasonable alternative. Bioreactors provide suitable environmental conditions for the production of commercially valuable plant metabolites as well as for micro propagation of plants, if they are designed and optimised to satisfiy the unique requirements of plant cell and tissue cultures and enable the development of feasible industrial processes. However, although considerable research efforts have been dedicated both from industry and academia, the industrial application of plant cell and tissue cultures have been limited and the full potential of these processes has yet to be realized. This book provides an overview of different types of bioreactors for various plant cell cultures such as plant cell suspension cultures, clonal propagation and organ cultures including shoots, hairy roots and somatic embryogenesis. The developments in large scale cultivation of plant cell and tissue cultures are critically outlined by presenting scale-up studies and state-of-the-art technologies, while focusing on different cell and tissue culture applications and bioreactors. Moreover, a structured set of information compiled in the form of a SWOT (strengths, weaknesses, opportunities, threats) analysis regarding the scale up of plant cell culture, organ culture and propagation has been presented to demonstrate the strengths and weaknesses and point out areas for further research. The large scale application of plant cell and tissue culture processes in industry depends greatly on the economics of the processes. Collaboration of interdisciplinary teams is imperative to improve the state-of-the-art and to increase best practices in this field.

    1. Introduction Bioactive compounds extracted from plants are widely used. The natural habitats for a large number of plants are rapidly destroyed leading to extinction of many valuable and even endemic species. Studies on the production of plant metabolites by callus and cell suspension cultures have been carried out on an increasing scale since the end of the 1950's. The prospect of using such culturing techniques is for obtaining secondary metabolites, such as active compounds for pharmaceuticalss and cosmetics, hormones, enzymes, proteins, antigens, food additives and natural pesticides from the harvest of the cultured cells or tissues. The large scale cultivation of tobacco and a variety of vegetable cells was examined from the late 1950's to early 1960's initiating more recent studies on the industrial application of plant cell culture techniquesin many countries. The first patent for the cultivation of plant tissue was received in 1956. Shortly afterwards, the National Aeronautics and Space Administration (NASA) started to support research in the field of plant cell cultures for regenerative life support systems (Sajc et al., 2000).
