Introduction: From the air we breathe to the water we drink to the food we eat, there are thousands upon thousands of bacteria that we interact with on a daily basis some are good and help us live healthy and productive lives, like the bacteria that is used to make and keep yogurt from spoiling (Wassenaar, 2002) . Now granted, not all bacteria are beneficial to us and can cause us a lot of harm. If bacteria are harming us, either by causing disease, contaminating our food, or harming the environment that we live in, one needs to identify the unknown bacteria so that the proper treatment and strategy can be developed to remedy the problem (Intrieri, 2014). In order to identify bacteria and other organisms, scientists have developed many different tests to differentiate microorganisms from each other their physical characteristics. There are many different physiological tests one can used to identify bacteria. For this project, one can use a spore stain to see if a bacteria can produce spores in response to nutrient depletion.(Intrieri, 2014) There is also the catalase tests, which show whether bacteria possesses the enzyme catalase, which can handle reactive oxygen species (Intrieri, 2014). There is also the oxidase test, which tests for the presence of oxidase in a bacteria, which indicates the bacteria contains cytochrome c (Intrieri, 2014). Another useful test to differentiate bacteria is the Entero-Plueri Test®, which performs multiple tests in one setting, like
