Abstract: | More than a century has passed since the first attempt to cultivate plant cells in vitro. During this time, plant cell cultures have become increasingly attractive and cost-effective alternatives to classical approaches for the mass production of plant-derived metabolites. Furthermore, plant cell culture is the only economically feasible way of producing some high-value metabolites (e.g., paclitaxel) from rare and/or threatened plants. This review summarizes recent advances in bioprocessing aspects of plant cell cultures, from callus culture to product formation, with particular emphasis on the development of suitable bioreactor configurations (e.g., disposable reactors) for plant cell culture-based processes; the optimization of bioreactor culture environments as a powerful means to improve yields; bioreactor operational modes (fed-batch, continuous, and perfusion); and biomonitoring approaches. Recent trends in downstream processing are also considered. This paper is dedicated to Prof. Dr. Mladenka P. Ilieva on the occasion of her 70th birthday. |
