Objectives

Students should understand basic concepts in microbiology, genetics, biology and physiology using examples from biotechnology. Students should become acquainted with the use of biological systems as means to obtain specialties or commodities that can not be obtained by chemical synthesis or as a strategy to add value to established chemical processes. On the laboratory classes students will acquire the necessary skills for manipulation of microorganisms and the techniques involved on their characterization.

Learning outcomes and competences

 - Application of biological systerms to industrial processes and environmental technology

 - Development o group work skills

 - Development of microbiology lab skills

Eligibility for exams

Admission to exams is granted by participation in classes according to the rules of the institution and if the grade attained on the lab component is higher than 8/20 points. Lab sessions are compulsory and failures in attendance will result in a classification of 0/20 on the corresponding session.

Calculation formula of final grade

Final classification (CF) is calculated by: CF = C1 + C2; C1 = 0.35 T1 + 0.35 T2 + 0.3 Lab where: T1 - Test 1 , minumum grade is 8/20 points T2 - test 2 scheduled for the first call of the exams period,  minumum grade is 8/20 points Lab - laboratory mark. For admission to exam this component has to be higher than 8/20 points. Rel - mini-reports. For admission to exam this component has to be higher than 8/20 points. C2 - continuous evaluation from the TP classes. Each student will be evaluated at least once during the semester either by making a short presentation with the highlights from the previous class or by answering 2 questions on separate classes. Grades will be situated on the following interval [-1.5, 1]. Students that are no present in class when they are called (or were not present on the previous class in the case of the presentation) will be graded with -1.5 points. Students that choose not to present or not ro reply to the questions will be graded with -0.5. Sutdents that choose to make the presentation or answer the questions wil be marked between [-1, 1. Students that were unable to reach the minimal grade in at least one of the tests (T1 ot T2) willl be evaluated by final exam (in the resit period) and their grade will be calculated as: CF= C1+C2 C1 = 0,7 E + 0,3 Lab where: E - final exam For approval, final mark must be higher or equal to 10/20 points.

Examinations or Special Assignments

Lab report to be delivered in printed version up to two weeks after the final lab sessio (until 4 pm).

Internship work/project

Not applicable

 

Special assessment (TE, DA, ...)

Final exam according to general rules. Students who did not attend the laboratory sessions due to  special status must execute one experimental work (choosen by the instructor) at a day to be arranged and must prepare a full report about that experimental work. Students will also undergo an oral examination of their experimental work where the experimental details and the main results and conclusions will be discussed.

Classification improvement

Students who want to improve their classification may take an exam in the resit period.
