Species

Propionibacterium is a genus of bacteria named for their unique metabolism: They are able to synthesize propionic acid by using unusual transcarboxylase enzymes.[2]

Its members are primarily facultative parasites and commensals of humans and other animals, living in and around the sweat glands, sebaceous glands, and other areas of the skin. They are virtually ubiquitous and do not cause problems for most people, but propionobacteria have been implicated in acne and other skin conditions.[3]

The strain Propionibacterium freudenreichii subsp. shermanii is used in cheesemaking to create CO2 bubbles that become "eyes", round holes in the cheese.[4]
