What type of bacteria require oxygen for survival?

Anaerobic bacteria
Facultative bacteria
Microaerophilic bacteria
Aerobic bacteria

The correct answer is: Aerobic bacteria

Aerobic bacteria are those that require oxygen for their survival and growth. These organisms utilize oxygen for cellular respiration, which is essential for generating the energy they need to thrive. Aerobic bacteria are commonly found in environments where oxygen is available, such as soil, water, and in the human body. In contrast, anaerobic bacteria do not need oxygen and may even find it toxic. Facultative bacteria can grow with or without oxygen, so they are flexible in their oxygen requirements. Microaerophilic bacteria need oxygen but at lower levels than what is typically found in the atmosphere. Understanding these differences is crucial for proper food safety practices, as the presence or absence of specific types of bacteria can heavily influence food preservation, spoilage, and safety.
