University of Maryland's Catalog Description

ENCH 485 Biochemical Engineering Laboratory (3) Six hours of laboratory per week. Pre- or co-requisite: ENCH482. Techniques of measuring pertinent parameters in fermentation reactors, quantification of production variables for primary and secondary metabolites such as enzymes and antibiotics, the insolubilization of enzymes for reactors, and the demonstration of separation techniques such as ultrafiltration and affinity chromatography.


Short Report 15%
Long/Video Reports (3@25% ea) 75%
Notebook & Lab Housekeeping 10%

Total 100%

The schedule will be pushed back when the University is closed due to snow. Reports are due one week following the completion of the experiment. No late reports will be accepted unless individually arranged with the instructor before the due date with a valid excuse.

Each of the four major experiments (e.g., oxygen mass transfer, transformation, fermentation, purification, enzyme kinetics, and immobilization) requires a report. Each group in consultation with fellow group members determines the objectives of each experiment, the procedures to be followed, and the measurements to be taken. Each group decides which type of report (short, long, or video) it wants to prepare for each experiment. Short reports should be no longer than 1 page of text, excluding tables, figures, and other supporting materials. Full length reports have no maximum nor minimum page limitations but are normally approximately 10 pages of text in length. Video reports are videotaped laboratory segments edited into a presentation format. You may want to borrow editing equipment from the instructor. You have a choice of either a) two long reports plus one video presentation plus one short reports or b) one long report plus two video presentations plus one short report. The written report, both short and long ones, must be prepared individually although the raw data are generated as a group effort. The items to be prepared individually include all components in the written report (text, data analysis, tables, figures, etc.). Each student submits one's own written report and receives an individual grade. Video reports, on the other hand, represent a group effort. The entire group analyzes the data, prepares tables/figures, and submits a finished video tape along with the original, unedited footage and receives one common grade for the finished product. Thus, teamwork is especially important in a video report.

Plagiarism and academic dishonesty will be dealt with harshly to the fullest extent of the University Regulations. It is your responsibility to consult the instructor whenever there is a doubt on the allowable material or the level of collaboration. The following is a message from the Student Honor Council on the consequences of academic dishonesty.

"The University of Maryland, College Park has a nationally recognized Code of Academic Integrity, administered by the Student Honor Council. This Code sets standards for academic integrity at Maryland for all undergraduate and graduate students. As a student you are responsible for upholding these standards for this course. It is very important for you to be aware of the consequences of cheating, fabrication, facilitation, and plagiarism. For more information on the Code of Academic Integrity or the Student Honor Council, please visit"

If you have a documented disability and wish to discuss academic accommodations with the instructor, please do so as soon as possible.
