Abstract:
1. A mutant lactic acid bacteria strain having a lower post-acidification than the parent strain from which it is derived, wherein said mutant strain results from the introduction into the genomic DNA of said parent strain, of a mutation of the codon encoding the HPr(His—P)-phosphorylatable histidine of the IIA domain of lactose permease, said mutation inducing the replacement of said histidine with a non-phosphorylatable amino acid, wherein the mutant strain is the mutant strain of S. thermophilus deposited on May 10, 2004, at the CNCM under number I-3213, and wherein the parent strain is a strain of Streptococcus thermophilus and in that this mutation introduces an alanine codon in place of histidine codon 552.
