Beschreibung
Zusammenfassung:	The invention herein relates generally to enhancing the survival and activity of probiotic Lactobacillus strains in mammals. Lactobacillus strain comprising a LacS transporter sequence having a sequence identity of at least 70% to SEQ ID NO: 1, and/or comprising a GH42 B-gal sequence, wherein the Lactobacillus strain is not a Lactobacillus reuteri strain. The invention comprises methods for cultivating and manufacturing probiotic Lactobacillus strains, and products containing such strains. In more detail the GC present invention relates to a composition comprising probiotic Lactobacillus strains, obtained by a step of growing the bacteria in a medium comprising galacto-oligosaccharides (GOS) ("pre-conditioning"), and administering said pre-conditioned bacteria together with GOS in the final product. The inventors have found that such method induces a boost in the beneficial effects of the probiotic bacteria, such as survival in the gastrointestinal tract.
