Learning Goals
The purpose of this course is to make known the different types of existing bioreactors. Students should recognize the importance of upstream and downstream processes of the bioreactor. It is also UC's objective to make known the different types of sterilization processes. This course will allow students to know the importance of agitation for mass and heat transfer in the bioreactor. Dimensioning homogeneous phase bioreactors and heterogeneous phase bioreactors is also the objective of this UC. Students should recognize that bioreactors may not have optimal agitation.
This UC allows to know the use of bioreactors in biogas production and algal biomass production.

Teaching Methods
The classes are theoretical-practical. In these classes will be held an exposition on the contents of the UC followed by exercise resolution and / or presentation of case studies.
During the semester there will be tests and a monographic work on a theme under the UC.
There will be the possibility of final exam.
The final note will be 70% of the average test or exam score and 30% of the monograph score.
