From the list below, choose the bacterial oxygen requirement (atleft) that properly matches the description (at right).
1. Facultative anaerobes: tolerate O2 but do notneed O2; metabolism is via fermentation
2. Microaerophiles: grow in presence of O2, but canalso grow without O2
3. Obligate aerobes: require O2 to survive anddo not tolerate poor O2 conditions
4. Aerotolerant anaerobes: killed with even brief exposure toO2
5. Obligate anaerobes: requires some O2, but highconcentrations of O2 are inhibitory
