Tubular bioreactors: case study of bioreactor performance for industrial production and scientific research.
Application of bioreactors is dominated by industrial production with the consequence that bioreactors also for scientific purposes are mainly used following an empiric pragmatic approach. For the sake of a breakthrough in biotechnology in general, and especially for advanced process development, a more systematic approach is emphasized here. This methodology in bioreactor performance studies is explained and the meaning clarified in a case study of a new type of tubular bioreactor. The central role of so-called "model bioreactors" in bench-scale applications is illustrated as a powerful contribution to the optimal design of bioreactors in technical scale. Pilot plant data in case of a tubular reactor for the production of ethanol with Zymomonas and biopesticides with Bacillus thuringiensis are presented.
