Fermentation Gone Wild: A Biochemistry Laboratory Experiment

Abstract

An experiment for the upper-level biochemistry laboratory is described in which students isolate a wild yeast from environmental sources and characterize the strain for its potential in the brewing industry. In addition to providing valuable experience in important biochemical techniques, this study also illustrates key principles of bioprospecting, the search for new biological sources with potential commercial or scientific value. By foraging for yeast in the wild, students explore the microbial diversity of their local environment and potentially find untapped sources of yeast that produce novel flavors and aromas. Overall, students engage with hands-on experience in bioprospecting, allowing them to appreciate the value of exploring biological diversity and its potential applications in the brewing industry.
