An obligate aerobe is an aerobic organism that requires oxygen to grow.

Bacillus sphaericus is an obligate aerobe bacterium used as a larvicide for mosquito control.

Though it is an obligate aerobe, it is able to survive in low-oxygen conditions by utilizing light-energy.

Leptospira interrogans is a Gram negative, obligate aerobe spirochete, with periplasmic flagella.

Cryptococcus aerius is an obligate aerobe, that has been previously isolated from soil samples and samples of sand.

An obligate aerobe, M. luteus is found in soil, dust, water and air, and as part of the normal flora of the mammalian skin.

Acetobacter aceti is an obligate aerobe which means that it requires oxygen to grow; it only has the ability for respiratory metabolism.

Unlike several other well-known species, B. subtilis has historically been classified as an obligate aerobe, though recent research has demonstrated that this is not strictly correct.

It is an obligate aerobe, but certain strains are capable of using nitrate instead of oxygen as a final electron acceptor during cellular respiration.

For the growth of bacteria, there must be a food supply, moisture, oxygen (if the bacteria is an obligate aerobe), and a certain minimum temperature (see bacteriology).
