Final answer:
Aerotolerant anaerobes are bacteria that have the enzyme superoxide dismutase (SOD) but lack the enzymes catalase and peroxidase. As a result, they cannot process oxygen for energy and do not perform aerobic respiration.
Step-by-step explanation:
The type of bacteria described in the question is aerotolerant anaerobes. These bacteria have the enzyme superoxide dismutase (SOD), but they lack the enzymes catalase and peroxidase. As a result, they are unable to process oxygen for energy through aerobic respiration.
Aerotolerant anaerobes can grow in the presence of oxygen, but they do not perform aerobic respiration. Most aerotolerant anaerobes are negative for the enzyme catalase. An example of an aerotolerant anaerobic bacteria is Lactobacillus acidophilus, which is used to make yogurt.
