IPA: //ˈɛəroʊb//
KK: /ˈɛəroʊb/
A living thing, like a bacterium, that needs oxygen to survive.
The aerobe thrived in the oxygen-rich environment of the laboratory.
Aerobe is formed from "aero-" (from Greek "aēr", meaning air) and "-be" (from Greek "bios", meaning life). The word refers to an organism that lives in the presence of air or requires oxygen for survival.
Think of 'air' ('aero-') being essential for 'life' ('-be'), which helps you remember that an aerobe is a life form that needs air to exist.
