New strains capable of producing conjugated linoleic acid, capsulated composition comprising them, and the functional food using them

摘要

The present invention relates to novel strains capable of producing conjugated linoleic acid (CLA). The strains include Bifidobacterium breve CBG-C2, Bifidobacterium pseudocartenulatum CBG-C4 and Enterococcus faecium CBG-C5. The strains are excellent in producing CLA and are able to secret the produced CLA to a medium or to accumulate in the bodies thereof. Also, the strains show strong resistance to antibiotics and acids such as stomach acid or bile salt. A composition comprising the strain according tot he present invention is prepared in the form a capsule comprising the strain according to the present invention and CLA encapsulated in a coating material comprising water soluble polysaccharides and may be used in functional foods and medicaments.
