Following from the previous question, C. jejuni is a chemoorganoheterotroph that relies on oxidative phosphorylation to generate ATP. Experiments have shown that under near-anaerobic conditions (1% or less oxygen), C. jejuni will migrate to 20 mM concentrations of dimethyl sulfoxide (DMSO), fumarate, nitrate, nitrite, and hydrogen peroxide, but will not do this when 6% or higher oxygen is present. Why would C. jejuni demonstrate this behavior?

Thiomicrospira denitrificans grows by gaining energy from the oxidation of reduced sulfur compounds such as hydrogen sulfide (H2S), thiosulfate ((S2O3)2-), or elemental sulfur (S), using oxygen or nitrate (NO3-) as electron acceptors. It uses CO2 as its carbon source. This organism would be classified as ______.
