The “obligate” subtype of these organisms settle to the bottom of a thio·glyco·late broth tube. For 10 points each:
[10e] Name this class of bacteria, whose inability to deal with ROS production renders them unable to survive in the presence of oxygen.
ANSWER: obligate anaerobes [or anaerobic]
[10h] In thioglycolate broth, these organisms cluster in an area a little below the top of the test tube. Campylobacter (“CAMP-ill-oh-back”-turr) species are examples of these organisms, which require oxygen, but at levels below normal atmospheric concentration.
ANSWER: microaerophiles [accept microaerophilic]
