Genomic Stability and Phenotypic Characteristics of Industrially Produced Lacticaseibacillus rhamnosus GG in a Yogurt Matrix.

Lacticaseibacillus rhamnosus GG is a widely marketed probiotic with well-documented probiotic properties. Previously, deletion of the mucus-adhesive genes in dairy isolates was reported. In this study, we examined the genome preservation of industrially produced L.

Lactobacillus rhamnosus GG Genomic and Phenotypic Stability in an Industrial Production Process.

GG is one of the most widely marketed and studied probiotic strains. In GG, the gene cluster encodes pili, which are important for some of the probiotic properties of the strain. A previous study showed that the DNA sequence of the gene cluster was not present in some GG variants isolated from liquid dairy products.
