摘要

Streptococcus thermophilus strain of which epsAD fragment presents a restriction profile after digestion by MnlI, FokI and Hind III restriction enzymes characterized by the DNA fragments from 344+- 2 base pair (bp), 341+- 2 bp, 305+- 2 bp, 299+- 2 bp, 277+- 2 bp, 210+- 2 bp, 160+- 2 bp, 142+- 2 bp, 100+- 2 bp, 79+- 2 bp, 75+- 2 bp, 66+- 2 bp, 42+- 2 bp, 23+- 2 bp and 9+- 2 bp, is claimed. Independent claims are included for: (1) a Streptococcus thermophilus strain deposited on June 14, 2006 in National collection of cultures of microorganisms under the number CNCM 1-3617; (2) a bacterial composition comprising the strain; (3) a preparation process of a food product, dietary supplement, dietetic supplement or a product with probiotic properties comprising using the strain; and (4) a dairy product comprising the strain or the bacterial composition.
