You will be setting up the yeast Sugar Fermentation of Yeast Lab Names: Period: INTRODUCTION Yeast are able to metabolize some foods, but not others. This type of fermentation uses yeast to break pyruvate, made by glycolysis, into acetylaldehyde which gives off a molecule of carbon dioxide. Yellow slant and butt- Glucose and lactose and/or sucrose fermentation. if a scientist were studying the effect of color of light on plant growth, the color of the light would be the independent variable and the growth of the plant would be the dependent variable. They also produce CO 2 and ethanol. The answer is energy released from molecules of the nucleotide adenosine triphosphate or ATP. Maltose fermentation differentiates Proteus vulgaris (positive) from Proteus mirabilis(negative). The sugar fermentation pattern may be unique to a particular species or strain (Figure 2). 3.
