Types of Bacteria (Oxygen Requirement)
by Atika Subari

1. Aerotolerant anaerobes
1.1. not use oxygen for growth
1.2. not killed by the presence of oxygen
1.3. not use oxygen as final electron acceptor
1.4. produce catalase or superoxide dismutase
1.5. fermentative organisms
1.6. eg: Lactobacillus
2. Facultative anaerobes
2.1. can grow in present / absence of oxygen
2.2. prefer use oxygen for growth
2.3. In oxygen-poor environment, cellular respiration may occur anaerobically, utilizing such compounds :
2.3.1. nitrates
2.3.2. sulfate
