Abstract

The present invention relates to the use of certain bacterial strains found among food grade bacteria, particularly among dairy starter cultures, to produce conjugated linoleic acid (CLA) in vitro by fermentation. In particular strains of propioni- or bifidobacteria, such as Propionibacterium freudenreichii or Bifidobacterium breve, are used. Said bacteria may be used to provide food or feed products enriched in CLA, and also pharmaceutical products containing CLA as active ingredients.
