The type of bacteria that does not require oxygen to grow is classified as anaerobic bacteria. These organisms thrive in environments devoid of oxygen and can carry out their metabolic processes anaerobically, meaning they can convert nutrients into energy without using oxygen.

Anaerobic bacteria can be found in various environments, including the human gut, where they play important roles in digestion, as well as in decaying matter where the oxygen supply is limited. This characteristic distinguishes them from aerobic bacteria, which depend on the presence of oxygen for survival and growth.

Facultative bacteria are capable of growth in both the presence and absence of oxygen, switching their metabolic pathways accordingly, but they are not strictly anaerobes. Pathogenic bacteria refer to bacteria that can cause disease but can fall into aerobic or anaerobic categories; thus, they don’t exclusively describe the oxygen requirements. This clarifies why anaerobic bacteria is the correct answer to the question about bacteria that do not require oxygen for growth.
