Lactic Acid Fermentation Lab Report

The activities alcohol fermentation and lactic acid fermentation allowed each group to gain a visual understanding of the way fermentation works. In the unrestricted alcohol fermentation part of the activity, each group had their own glass fermentation chamber to pour a solution in. In my group’s fermentation chamber we used starch solution alone. In the alcohol fermentation groups had a total of eight combinations to put into test tubes. In the lactic acid fermentation groups were able to make sauerkraut and yogurt using material like skimmed milk, cabbage, and yogurt culture. The class as a whole waited an entire week before making concluding observation on both alcohol and lactic acid fermentations.
Introduction
Fermentation can best be described as a metabolic breakdown that requires no oxygen and will still produce ATP. The two types of fermentations that the group learned about was alcohol and lactic acid fermentation. The lab on alcohol and lactic acid fermentation allowed each group to look at the way fermentation works. Through lactic acid fermentation, the groups were able to “produce” things like yogurt out of simple substances like skimmed milk and yogurt culture. With alcohol fermentation, the groups examined different types of sugar solutions combined with yeast and amylase. Moreover, with this lab we able to understand …show more content…
We were edified on how to properly use, clean, and handle test tubes. Each person was to handle each object with care. Although lab jackets were option, they were essential, for they helped prevent spills on one’s clothing. If a test tube or chamber was broken, the group was to clean the spill up immediately. For the alcohol and lactic acid fermentation lab, each person was required have on closed toed shoes and long pants. Thus, with the proper clothing, one prevented themselves from a lot of injuries.
