Yeast Growth Depending on Sugar Complexity

Adrienne Allen, Laurianne Fisher, Tyler Ryan, Wesley Caswell, Rachel Crisp


With the intention of determining if the rate of yeast growth is increased with more complex sugars, an experiment involving three treatments using different sugars was conducted using sugars of varying complexity. We predicted that sucrose, the most complex sugar used would increase the rate of growth the most, because of the higher number of bonds which suggests more energy is available to the yeast.
