Laboratory of Biological Technologies

Base Knowledge

Basic notions of enzyme kinetics and food technology

Teaching Methodologies

Laboratory classes where the various practical assignments are carried out by group. During classes, students are confronted with relevant questions in order to assess how they prepared for the work and enhance the understanding of the acquired knowledge. During this course will be performed oral discussions of theoretical concepts, obtained results and reports. There is also a work presentation and oral defense at the end of this course unit.

Learning Results

The objectives of the course are to introduce the student to the field of Biological and Enzymatic Technology, with special emphasis on biological and enzymatic industrial transformation, enzymatic kinetics, methods of biocatalysts immobilization and application in reactors. It is intended that the student acquires the following skills: i) recognize the main industrial enzymatic and biological processes; ii) experimentally determine the kinetic parameters of the Michaelis-Menten model for free and immobilized enzymes; iii) experimentally determine the parameters of empirical models for continuous reactors with immobilized enzymes; iv) operate biological and enzymatic processes of industrial production; v) organize and manage group work and vi) report the performed work, discuss and analyze the experimental results.

Program

The program content consists of the consolidation of theoretical bases regarding enzymatic and biological technologies, lectured throughout the course, and carrying out experimental group work. The experimental work includes carrying out the laboratorial work, the preparation of the written report, and the analysis and discussion of the results.

The experimental works to be carried out include: i) Biological and enzymatic industrial transformations (enzymatic and fermentative processes); ii) Enzymatic kinetics and temperature dependence; iii) Immobilization of biocatalysts and application in continuous reactors.
