Some of the stuff below will guide us for the E-broth. Preparation of the Medium. Medium is the name we give to the food we grow our microbes in. Medium must contain everything our yeast needs. First we need to figure out what this yeast needs.
Bakers use flour, sugar, and water to make bread.
Recall that living organisms need carbon source, engery source, nitrogen source, minerals, and vitamins. We will try corn syrup and water in this experiment. We will hope the water has enough minerals. This mixture has very little nitrogen and will don't know if the yeast will be able to grow, if it does not grow we will try to find a nitrogen source to add. It tapwater does not have enough minerals, we could try water from a mud puddle or soil water made by mixing soil with water and using the clear supernatant water after the mud has settled.
