Atmosphere.~--The question as to whether the organism under observation is (a) an obligate aerobe, (b) a facultative anaerobe, or (c) an obligate anaerobe is roughly decided by the appearance of cultivations in the fermentation tubes.

Obvious growth in the closed branch as well as in the bulb or in the inverted gas tube as well as in the bulk of the medium will indicate that it is a facultative anaerobe; whilst growth only occurring in the bulb or in the closed branch shows that it is an obligate aerobe or anaerobe respectively.

Fine parallel filaments growing out into medium liquefying at surface; _c_, a rapid liquefying form; _d_, a gas-producing form that grows equally well in lower part of tube as at surface (facultative anaerobe); _e_, an obligate anaerobe, that develops only in absence of air.] The microscopical examination of any germ is quite as essential as the determination of culture characteristics; in fact, the two must go hand in hand.

After considerable work with cultures, they concluded that the bacillus is neither an aerobe nor an anaerobe, in the ordinary sense, but exhibits a very peculiar behavior in respect to oxygen, requiring for its development a partial pressure of oxygen somewhat less than that present in the atmosphere.
