Course Overview

This course introduces the fundamentals of microbiology and biochemistry, which are necessary for understanding and designing biotechnological processes.  The kinetics of enzymatic reactions and of microbial growth is presented. Focus is given to mass balances for enzymatic reactions and for microbial fermentations in different types of reactors: batch, continuous, fed-batch.  The mass and heat transfer theory developed as part of other courses is applied to biochemical process, with focus on substrate, oxygen and heat transfer.  The design and scale-up of biochemical processes is presented. Some typical biochemical processes are described.
