Students will complete a series of activities designed to introduce them to the science of Biomanufacturing.
Biomanufacturing or bioprocessing is when microorganisms, living cells or their components are used to produce a desired end product. For example, Novo Nordisk, a world leader in diabetes care that has a facility in Clayton, North Carolina, produces insulin using a genetically modified strain of yeast. Biomanufacturing facilities use bioreactors to grow the microbes that produce the desired product. Bioreactors are usually made of stainless steel and vary greatly in size (few liters to thousands). Bioreactors are typically cylindrical shape and their design is very complex in order to create the perfect conditions for growing microorganisms. The bioreactors are specifically engineered to monitor and control the temperature, pH and oxygen. Growth of cells in bioreactors is considered to be an “Upstream Process” in biomanufacturing. In this experiment students will create a bench-scale bioreactor and execute a form of bioprocessing that has been around for centuries: microbial fermentation of yeast. The level of fermentation will be monitored through carbon dioxide output using a water displacement set up.
This lesson will take three to four, forty five minute class periods.
Each activity contains a chart of the materials that are needed for that activity.
Each activity lists any pre-activities or demonstrations that should be conducted.
The teacher may wish to load the Power Point presentation on a website or local school server and have the students navigate the lesson independently for homework in order to save class time.
The teacher may want to add narration to the Power Point if students are working independently in order to better assist students with reading disabilities.
If lab equipment and supplies are limited, the teacher may wish to conduct the experiments as a classroom demonstration.
