TL;DR: Analysis of gut microbiota composition in newborn to centenarian Japanese subjects revealed certain transition types of microbiota were enriched in infants, adults, elderly individuals and both infant and elderly subjects, and transporter property prediction results suggest that nutrients in the gut might play an important role in changing the Gut microbiota composition with age.
Journal ArticleDOI
Isolation of tannin-degrading lactobacilli from humans and fermented foods.
TL;DR: Lactobacilli with tannase activity were isolated from human feces and fermented foods and confirmed that this enzymatic activity is a phenotypic property common to these three species.
Journal ArticleDOI
Streptococcus gallolyticus sp. nov.; Gallate Degrading Organisms Formerly Assigned to Streptococcus bovis
TL;DR: It was found that the gallate degrading strains of S. bovis should be re-assigned to a new species, for which the name Streptococcus gallolyticus sp.
Journal ArticleDOI
Age-Related Changes in the Composition of Gut Bifidobacterium Species.
TL;DR: The results revealed the patterns and transition points with respect to compositional changes of Bifidobacterium species that occur with ageing, and the findings indicate that there may be symbiotic associations between some of these species in the gut microbiota.
Journal ArticleDOI
Identification and cloning of a gene encoding tannase (tannin acylhydrolase) from Lactobacillus plantarum ATCC 14917T
TL;DR: Subsequent enzymatic characterization revealed that TanLpl was most active in an alkaline pH range at 40 degrees C, which was quite different from that observed for a fungal tannase of Aspergillus oryzae.
