Quantitative real-time PCR assays to identify and quantify fecal Bifidobacterium species in infants receiving a prebiotic infant formula

Article Abstract:

The different Bifidobacterium species in breast-fed (BF) infants and infants receiving a standard formula (SF) or a standard formula supplemented with a specific prebioticgalacto-oligosaccharides/fructo-oligosaccharides (GOS/FOS) mixture oligosaccharides (OSF) is studied. The results revealed a significant increase in the total amount of fecal bifidobacteria in infants receiving the prebiotic formula (OSF), with a diversity of Bifidobacterium species similar to breast-fed infants.

Purification and characterization of alpha-L-arabinopyranosidase and alpha-L-arabinofuranosidase and Bifidobacterium breve K-110, a human intestinal

Article Abstract:

The alpha- L-arabinopyranose and alpha-L-arabinofuranose linkages of genosides Rb2 and Rc were easily hydrolyzed to ginsenoside Rd by Bifidobacterium breve K- 110, a human anaerobic intestinal bacterium. The findings suggest that the biochemical properties and substrate specificities of these purified enzymes are different from those of previously purified alpha- L-arabinosidases.

In vitro fermentation of breast milk oligosaccharides by Bifidobacterium infantis and Lactobacillus gasseri

Article Abstract:

The study demonstrated Bifidobacterium infantis to ferment purified human milk oligosaccharides (HMO) as a sole carbon source, while another gut commensal, Lactobacillus gasseri, did not ferment HMO. The results support the hypothesis that HMO selectively amplify bacterial populations in the infant intestine.
