Brit.

/ˌprəʊpɪˌɒnɪbakˈtɪərɪəm/, U.S.

/ˈˌproʊpiˌɑniˌbækˈtɪriəm/

Origin: A borrowing from Latin. Etymon: Latin Propionibacterium.

Etymology: < scientific Latin Propionibacterium, genus name (S. Orla-Jensen 1909, in Centralbl. f. Bakteriol., Parasitenkunde u. Infektionskrankheiten (Zweite Abt.) 22 337) < propion- (see propio- comb. form) + -i- -i- connective + bacterium bacterium n.

Bacteriology.

A genus of bacteria comprising rod-shaped Gram-positive forms which metabolize simple carbohydrates to produce propanoic (propionic) acid, some being involved in the fermentation of dairy products and in the aetiology of acne; (also propionibacterium) a bacterium of this genus.
