Inhaltliche Voraussetzungen (erwartete Kenntnisse)

Participants will have to recall their knowledge from different lectures and disciplines in the field of biotechnology and create new connections.


After the positive completion of the course the students can:

1) Describe essential concepts of reaction kinetics (mass balance, mass transfer) and reactor types
2) Recall and explain important catalytic constants (Km, kcat,...) and process parameters (T, pH, [S], [P], [I],,...) which affect enzymatic reactions and their applications in industrial scale processes
3) Derive and interprete process diagrams (substrate conversion, product formation, reaction rate,...) and performance numbers (space-time yield, specific productivity, total turnover number,...)
4) Apply fundamental principles of biocatalysis for the engineering of a biochemical reaction
5) Asses and argue the influence of catalytic constants on enzymatic processes
6) Generate solutions for possible problems caused by non-ideal enzymes and poor reaction conditions
