This odor-eating bacteria researchers found is called methylotrophic bacteria, according to Science Daily:

Researchers have isolated bacteria which can grow on and ‘mop up’ smelly compounds in the mouth that are linked to bad breath. These smelly, highly reactive ‘one-carbon’ compounds are naturally produced from the breakdown of sulphur-containing amino acids in the mouth.

We bought some anti-odor foot aerosol spray for our gym shoes. After we work out I spray those bad boys. Still doesn’t seem to do a huge amount of good. Maybe it’s time to harvest some bacteria!
