IS6503 Optimized Fermentation of Yeast
Through the use of a gas pressure sensor, you will be able to monitor the pressure change in a sealed environment and the pressure change provides an indication of the rate of CO2 production. Yeast will be exposed to four different sugar solutions and the overall pressure changes for fermentation in each sugar solution will be compared, providing an indication as to how effective the fermentation process is in the presence of each of the sugars. With this data students will determine the optimum food source for yeast by monitoring growth rate and respiration. There are enough materials for 15 groups and includes a Teacher’s Guide and Student copymasters.
