Varying microenvironments: oxygen presence or absence Microbes vary in their tolerance of and requirements for oxygen. While obligate aerobes require oxygen to survive, other microbes can be killed by oxygen. What type(s) of microbe is/are likely to be found in the following locations of the body? Drag each of the types of environment to the bin that best describes the most common microbes (obligate aerobes, obligate anaerobes, facultative anaerobes, and/or aerotolerant organisms) found there. Microbiology Now Chapter 23 Question 1 Microbes vary in their tolerance of and requirements for oxygen. While obligate aerobes require oxygen to survive, other microbes can be killed by oxygen. What type(s) of microbe is/are likely to be found in the following locations of the body? Drag each of the types of environment to the bin that best describes the most common microbes (obligate aerobes, obligate anaerobes, facultative anaerobes, and/or aerotolerant organisms) found there. While the normal microbiota are important for normal health and functioning, it is important to have defenses against foreign microbes.
