The story of the word

Pasteur coined aérobie in 1863 for the microbes that need air, having found others that fermented happily without it and named those anaérobies. The word stayed inside microbiology for most of a century. Physiologists then applied it to muscle metabolism, the fitness industry took it from them, and a term for bacteria now appears on treadmill displays.
