摘要： The application is directed to a method to manufacture pasta-filata cheese based on cultures comprising or consisting of either 1) at least a galactose-positive Streptococcus thermophilus strain as defined herein or 2) at least a Streptococcus thermophilus strain and a Lactococcus lactis strain, and to a stretched curd or cheese produced by this method. The application is also directed to a culture or kit-of-part comprising or consisting of a) a galactose-positive Streptococcus thermophilus strain as defined herein, and b) Lactococcus strain(s) and/or Lactobacillus helveticus strain(s).

摘要： The invention relates to a method for generating a Streptococcus thermophilus strain exhibiting a “high galactose utilization” profile, which is characterized by a high percentage of consumed galactose at the maximum speed of lactose consumption and optionally a high percentage of consumed galactose at the end of lactose consumption (both as determined by assay I), comprising modifying the sequence of the gal-lac gene cluster. The invention also relates to a Streptococcus thermophilus strain obtained or obtainable by this method, to a Streptococcus thermophilus strain characterized both by the sequence of its gal-lac gene cluster and its “high galactose utilization” profile, to a culture and kit-of part comprising such strains, as well as to the use of such strains in food applications.
