Teaching Methodologies
The theoretical lectures are predominantly expository and it will prevail a strong interaction between the concepts taught and their practical application.
In the theoretical-practical classes the students will solve exercises under the guidance of the lecturer.
In the practical laboratory classes the fundamentals of the experimental work to be done are presented and discussed, and students are encouraged to do a previous reading of the recommended bibliography. A critical analysis of the obtained results will be done, and a written report will be prepared to develop critical thinking skills and the power of synthesis.
The formal lectures will be complemented by periods of individual attendance.
Learning Results
The course aims to provide students with the knowledge of several unit operations and separation techniques used for the purification of products obtained in biotechnological processes from different biological sources (microorganisms, animals and plants), at the laboratorial and industrial scales. Emphasis is given on the initial downstream stages, namely clarification, concentration and low-resolution purification techniques. In this context, the course allows to develop competencies related with the design of pieces of equipment, as well as with the calculation of their operating conditions. On the personal level, the course will help students to develop autonomous and critical thinking.
Program
A. Theoretical component
1. Introduction. Characterization of biotechnological processes. Importance of biotechnological processes in the world scenario.
2. Main steps of a generic industrial biotechnological process: upstream processing, bioreactor, downstream processing.
3. Downstream processing: removal of cells and cell debris, primary isolation, purification and final isolation. Main unit operations used in each stage.
4. Separation of insolubles: filtration and centrifugation. Equipment available. Theoretical concepts and calculation of operating conditions.
5. Cellular rupture: mechanical and non-mechanical methods. Some details of the most common pieces of equipment.
6. Separation of solubles: extraction and adsorption. Extraction column – concept of ideal stage. Adsorption isotherms. Equipment available. Calculation of operating conditions.
B. Practical component
Laboratory practice: conventional solid-liquid extraction from a vegetable matrix.
