BIOL 2250L – Microbiology for the Heath Sciences Lab 6 – Oxygen Requirements 1 Background There many important factors that is essential in order for a bacterium to grow. Oxygen is one of those important factors. Without oxygen present, some bacteria will not grow and in the presence of oxygen, some bacteria will die. Bacteria can be divided into several groups in accordance to use of oxygen. Obligate aerobes require oxygen to survive whereas obligate anaerobes cannot tolerate the presence of oxygen. Facultative anaerobes can grow with or without oxygen. Microaerophiles grow at low concentrations of oxygen. Aerotolerant cannot use oxygen but can tolerate it well. To test for oxygen requirements in the laboratory, we can use a semisolid media called thioglycollate broth . In this broth, there is a pink indicator to demonstrate that oxygen is present in the broth. When oxygen is used, it will disappear.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
