Modulation of Tissue Fatty Acid Composition of a Host by Human Gut Bacteria
The current invention provides use of a CLA-producing bacterium for the in vivo conversion in the gut of polyunsaturated fatty acids to CLA. The CLA-producing bacterium is selected from one or more of the group consisting of propionibacteria, lactobacilli, lactococci and streptococci, and bifidobacteria.

26 . A method for altering a fatty acid composition of an internal organ of a body of a subject, the method comprising administering to the subject a product comprising a bacterium selected from one or more of Bifidobacterium breve as deposited at the National Culture of Industrial and Marine Bacteria under accession no. 702258, Bifidobacterium breve DPC 6330 as deposited at the National Culture of Industrial and Marine Bacteria under accession no. 41497 on Sep. 28, 2007, or Bifidobacterium longum DPC as deposited at the National Culture of Industrial and Marine Bacteria under accession no. 41508 on Oct. 18, 2007.
27 . The method of claim 26 , wherein the internal organ is a liver.
28 . The method of claim 26 , wherein the product further comprises a pharmaceutically acceptable additive.
29 . The method of claim 26 , wherein the product further comprises a nutritionally acceptable additive.
30 . The method of claim 26 , wherein the product is a foodstuff selected from a yogurt, a yogurt drink, a cheese, a milk, a spread, a fruit juice, a flavored water, or unflavored water.
31 . The method of claim 26 , wherein the product further comprises a substrate, which is capable of being converted into a bioactive compound in vivo by the bacterium.
32 . The method of claim 31 , wherein the substrate is a polyunsaturated fatty acid.

34 . A foodstuff comprising a bacterium selected from one or more of Bifidobacterium breve as deposited at the National Culture of Industrial and Marine Bacteria under accession no. 702258, Bifidobacterium breve DPC 6330 as deposited at the National Culture of Industrial and Marine Bacteria under accession no. 41497 on Sep. 28, 2007, or Bifidobacterium longum DPC as deposited at the National Culture of Industrial and Marine Bacteria under accession no. 41508 on Oct. 18, 2007, and an additive.
35 . The foodstuff of claim 34 , wherein the additive is a nutritionally acceptable additive.
36 . The foodstuff of claim 35 , further comprising a substrate which is capable of being converted into a bioactive compound in vivo by the bacterium.
37 . The foodstuff of claim 36 , wherein the substrate is a polyunsaturated fatty acid.
38 . The foodstuff of claim 37 , wherein the polyunsaturated fatty acid is linoleic acid, linolenic acid, oleic acid, palmitic acid, or stearic acid.
