biostudies-literature00600Unknown78(18)Su MSLactobacillus reuteri is both a gut symbiont and a stable member of sourdough microbiota. This study employed multilocus sequence analysis and an analysis of host-specific physiological and genetic traits to assign five sourdough isolates to rodent- or human-specific lineages. Comparative genome hybridization revealed that the model sourdough isolate LTH2584 had a genome content very similar to that of the model rodent isolate 100-23. These results demonstrate that sourdough isolates of L. reuteri are of intestinal origin.Applied and environmental microbiology6777-80https://www.ebi.ac.uk/biostudies/studies/S-EPMC3426701biostudies-literatureIntestinal origin of sourdough Lactobacillus reuteri isolates as revealed by phylogenetic, genetic, and physiological analysis.PMC3426701Ganzle MGSu MSWalter JOh PL60falseIntestinal origin of sourdough Lactobacillus reuteri isolates as revealed by phylogenetic, genetic, and physiological analysis.Lactobacillus reuteri is both a gut symbiont and a stable member of sourdough microbiota.
