Question

Quizplus · Accepted Answer

The fact that Clostridium tetani forms spores in the presence of oxygen indicates that these bacteria are anaerobic, meaning they thrive in an environment where there is no oxygen. The spores are a protective mechanism that allows the bacteria to survive in harsh environments, including exposure to oxygen. Autotrophic refers to organisms that can produce their own food, and halophilic refers to those that thrive in salty conditions. Neither of these terms apply to Clostridium tetani in this context.
