UW-Stout/Hydrogen Peroxide SP22

Introduction

Hydrogen Peroxide (H2O2) is a very strong oxidizer and antiseptic that is often used in dilute forms. The overall compound is found in biological systems but is in short lived reactions due to it's high toxicity over time. The goal of our experiment was to test how multiple yeast strains with knockout genes would respond in the presence of varying concentrations of hydrogen peroxide.
