Quizplus · Accepted Answer

The moderate growth in the candle jar (which creates a low oxygen environment) and the anaerobic jar (which creates an oxygen-free environment) suggests that this species can grow in the absence of oxygen. However, the heavy growth on the incubator shelf (which has normal atmospheric oxygen levels) suggests that this species can also grow in the presence of oxygen. Therefore, this species is likely a facultative anaerobe.
