Isolation, identification and characterization of strains with probiotic activity, from faeces of infants fed exclusively with breast milk
The invention relates to probiotic micro-organisms isolated from faeces of children exclusively fed with breast milk. Said microorganisms are used in the food or pharmaceutical industry, especially for use in infant formula milk, due to their probiotic properties which have beneficial effects on the health of those ingesting them. Said microorganisms consist of Lactobacillus rhamnosus HERO 22A (CNCM I-4036), Lactobacillus paracasei HERO 7 (CNCM I-4034) and Bifidobacterium breve HERO 15B (CNCM I-4035).
1. An isolated strain of probiotic microorganism isolated from faeces of children exclusively fed with breast milk, wherein said strain is Lactobacillus rhamnosus HERO 22A (CNCM I-4036).
2. The strain of claim 1 , wherein said strain is in the form of a pure biological culture.
3. The strain of claim 1 , wherein said strain is in the form of viable cells.
4. The strain of claim 1 , wherein said strain is in the form of non-viable cells.
5. A formulation comprising the strain of claim 1 and a carrier.
6. The formulation according to claim 5 , wherein said formulation further comprises a strain selected from the group consisting of Lactobacillus paracasei HERO 7 (CNCM I-4034) and Bifidobacterium breve HERO 15B (CNCM I-4035).
7. The formulation according to claim 5 , wherein said formulation further comprises another probiotic material.
8. The formulation according to claim 5 , wherein said formulation further comprises prebiotic material.
9. The formulation according to claim 5 , wherein said formulation further comprises a carrier suitable for the ingestion thereof.
10. The formulation according to claim 9 , wherein said carrier is a pharmaceutically acceptable carrier selected from the group consisting of capsules, tablets and powders.
11. The formulation according to claim 10 , wherein said food product is selected from the group consisting of milk; fermented milk and cheeses; cereals; bread doughs; soups; dehydrated food products; fermented meat products; fruit derivatives; juices and soft drinks.
12. The formulation according to claim 9 , wherein said carrier is a food product.
13. The strain according to claim 1 , wherein said strain is present in infant formula milk.
14. The strain according to claim 1 , wherein said strain is present in a food product selected from the group consisting of ready-to-eat infant milk, infant cereals, and infant foods.
15. The strain according to claim 1 , wherein said strain is present in a food supplement.
16. The strain according to claim 1 , wherein said strain is present in a formulation for oral and/or enteral nutrition.
17. The strain according to claim 1 , wherein said strain is present in a pharmaceutical product.
