Quizplus · Accepted Answer

An aerobe is an organism that can use oxygen in metabolism and has the enzymes to process toxic oxygen products. This includes both obligate aerobes, which require oxygen for growth, and facultative anaerobes, which can grow in the presence or absence of oxygen. Microaerophiles require a low level of oxygen and obligate anaerobes cannot tolerate oxygen. Therefore, the best choice for an organism that can use gaseous oxygen in metabolism and has the enzymes to process toxic oxygen products is simply an aerobe, without specifying whether it is obligate or facultative.
