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