Get prepared for a lab course in microbiology… with a video!

Marius R. Saltvedt explains the theory behind the diauxic growth of V. natriegens in a mixture of glucose and rhamnose, and introduces to the practical aspects of the experiment.

Teachers in BIO104 – Comparative physiology have been delivered their first video for the lab course in microbiology taught at BIO during the spring semester. The course introduces to the bi-phasic (diauxic) growth of Vibrio natriegens in a mixture of two distinct carbon sources. In this short video which you can watch further below, Marius Rydningen Saltvedt, MSc student in microbiology demonstrates the practical aspects of the experiment. He also explains the theory behind the bi-phasic bacterial growth and absorbance measurements. Additionally, Marius provides students with a guideline on how to manage their freshly acquired data in Excel and how to create a simple graph based on this simple dataset in a few clicks.

The video, which will soon be available to all on the Teach2Learn website as well as on bioST@TS, is part of bioCEED’s effort to stimulate production and use of media-based teaching material. Short videos come handy not only when introducing subjects and curricula, but also when demonstrating lab and field methods. They are even more relevant when produced “in house” as they illustrate how things are done by local researchers, teachers and students with actual research gears.




Note that bioCEED’s project Teach2Learn has also a growing library of videos made in connection with the following courses and which are used by biology teachers as illustrating material:
