If at bottom, it indicates anaerobic tendencies. If limited to top of medium, it indi- cates decidedly aerobic tendencies. (Most bacteria are decidedly aerobic; that is, they require free oxygen to thrive.) The test-tube cultures do not necessarily represent pure cultures, and the student cannot know whether the growths in the test-tubes represent the predominating bacterial flora in the substance from which the inoculations were made.
