""'Nitrosomonas halophila " "'is a ammonia-oxidizing, aerobe, Gram-negative bacterium from the genus of Nitrosomonas . " Nitrosomonas halophila " uses the enzyme Ammonia monooxygenase.

M . sedula is a cocci, roughly 1 um in diameter with pilus-like structures protruding from its surface when viewed via electron microscopy . That is an obligate aerobe that grows best at 75C and pH 2.0.

""'Virgibacillus " "'is a genus of Gram-positive, rod-shaped ( bacillus ) bacteria and a member of the phylum Firmicutes . " Virgibacillus " species can be obligate aerobes ( oxygen reliant ), or facultative anaerobes and catalase enzyme positive.

On a macroscopic scale, this would of course become complicated because the organism as a whole has to shut down gracefully, but you get my drift . Not needing air continuously seems to be a significant advantage, so I'm guessing there are deep-seated design issues for obligate aerobes that prevent this from being possible-- but which?

Because " A . thiooxidans " derives its energy from inorganic elemental sulfur, carbon directly from the atmosphere, and nitrogen from ammonium sulfate and other inorganic salts, and also because of its small mineral requirements, this autotrophic microorganism was likely among the first aerobes contributing to weathering through the formation of sulfuric acid, which interacted with insoluble phosphates, carbonates, and silicates.

A member of the genus " Bacillus ", " B . subtilis " is rod-shaped, and can form a tough, protective endospore, allowing it to tolerate extreme environmental conditions . " B . subtilis " has historically been classified as an obligate aerobe, though evidence exists that it is a facultative aerobe . " B . subtilis " is considered the best studied Gram-positive bacterium and a model organism to study bacterial chromosome replication and cell differentiation.
