1st-2nd semester: general information about what we did

Test of equipment and fundamental principles

To test the electrorotation equipment we replicated the methods and experiment done by Anders Jansen as well we compered dry and wet yeast.

We started by growing the dry yeast to a concentration of 8,8*10^7 cells per ml and the wet yeast to a concentration of 8,6*10^7 cells per ml, we calculated this as follows. 2 grams of dry yeast and 3,25 grams of wet yeast. We then calculate the given density of yeast cells in each yest type, which gives us 8,6*10^10 cells for wet yeast and 8,8*10^9 cells for the dry yeast. We then use the formula C1*V1=C2*V2 formula to calculate the given concentration of cells when we add 49,5 ml of tap water to each culture. we then add 2g of sugar to each culture acting as a food source. Each culture was then grown for 30 to 40 minutes giving the cultures depending on how active they appeared to be based on pressure and heat generation.

Cells from each culture where then placed in the electrorotation chamber and the equipment was tested, the equipment functioned as hoped and no difference was found between the cultures.

3rd semester: general and more detailed information about what we did and our findings
