The course focuses on understanding the whole process of industrial bioprocesses e.g. cell cultivation, upstream and downstream processes, process interactions and engineering aspects of the process. The subject is based on expansion, synthesis and application of knowledge gained in basic subjects such as microbiology, biochemistry, physical chemistry and chemical engineering to bioengineering aspects of industrial bioprocesses. The subject brings new or significantly expanding existing knowledge in the field of mass balance bioprocesses, types of bioreactors and methods of management and control of bioprocesses.

Attendance at lectures is recommended, but not controlled. An integral part of the teaching is an e-learning course divided into blocks with a complete set of knowledge including support materials and interactive simulation modules enabling simulations of cultivation techniques. Consultations are provided upon request. Last update: Halecký Martin (27.03.2025)

Lectures with practical cases and derivation of mathematical relationships and engineered solutions with an emphasis on understanding the complexity and the necessity of synthesizing previously and newly acquired knowledge and skills. Exercises with demonstrative calculations in Excel and examples of the behavior of biological systems in simulation modules in the e-learning course. Students apply theoretical knowledge from lectures in the context of discussions on typical practical examples. Last update: Halecký Martin (27.03.2025)

The exam is based on an oral form. The student draws three questions that are cross-sectionally related to the topics of the course and answers these questions as part of the oral exam. The condition for granting credit is passing one written credit test at the end of the semester. The test (total of 30 marks) consists of questions with a written answers (18 marks) and a quiz (12 marks). Credit is granted if the average of at least half of the points of both the entire test (15 marks) and both parts of the test (at least 9 marks for questions with a written answers and at least 6 marks for the quiz) is achieved. If these conditions are not met, the student repeats the credit test. The final grade is given by the weighted average of two values: 1. the average of the marks of the continuous written tests from the exercises (weight 20%) and 2. the marks of the exam (weight 80%). However, if the exam is evaluated with a grade of F, the final grade is also an F. Last update: Halecký Martin (27.03.2025)
