Main themes
From design to scale-up on a pilot scale of microbial and enzymatic processes. Theoretical and methodological foundations of applied chemical kinetics and design of chemical reactors with the characteristics (kinetics and transport phenomena) of biochemical and microbiological processes in order to systematize the principles underlying the analysis and design/sizing of bioreactors. Specifics:
(Micro)biological processes characterized kinetically and thermodynamically : cell growth, its measurement or estimation, use of substrate(s), formation of product(s). Yields. Productivities. Kinetic models. Parameter estimation. The methodology of material and energy balances for the analysis of biotechnological systems and of their performance. Batch, continuous, semi- continuous reactors. Transport phenomena applied to the analysis of aeration, agitation, rheology, scale-up and sterilization of bioreactors.

Content
Definitions: Definitions in bioengineering - quantities and reactors - microbial processes ' yields of biological processes in a reactor. Kinetic models of microbial growth. Modeling of a batch reactor - modeling of a continuous stirred biological system with and without recycling ' two-stage continuous stirred systems. Enzymatic process reactors - design and performance. Sterilization processes. Scale-up from laboratory scale through pilot scale to industrial scale. Bioseparations engineering. Ideal recovery process: primary separation, isolation, purification and polishing. Separation devices in industrial cell culture: continuous perfusion reactor with cell retention. Advantages and limitations of each design in an industrial context.
Teaching methods
1. Lectures, lectures with guided questions, including presentations of concrete examples from industry with case analysis by the instructor [conventional lectures, interactive presentations using audiovisual equipment (video projections, powerpoint)]
2. Exercise sessions in teams, guided. These exercises are designed to familiarize the student with the methodology of solving quantitative problems in the design and analysis of bioprocesses: makes use of calculations for sizing or performance, construction of flow sheets combining unit operations, search of real values of constants or other parameters of correlations useful in design or modeling / optimization of bioprocesses.
The activity begins with a face-to-face presence only
Evaluation methods
Writtenexamination in 2 parts
1. Examination requiring short answers but based on a theoretical development
2. Examination focused on problem solving
Other information
This course can be given in English.
