Pour Some Sugar On Me: How do different sugars affect yeast fermentation?

Abstract

Research on yeast used for biofuels and bioethanol led us to the question of; which sugar, when added to yeast and water, yields the most CO₂? From this, we formulated our hypothesis: if yeast is combined with water, rice sugar and pure glucose, it will produce more CO₂ than yeast combined with water, just rice sugar, or yeast combined with rice sugar and sucrose or lactose. To evaluate our hypothesis we measured the amount of CO₂ produced from mixing yeast with various sugars. We found that…..
