Population dynamics of Bifidobacterium species in human feces during raffinose administration monitored by fluorescence in situ hybridization-flow cytometry

Article Abstract:

The population dynamics of bifidobacteria in human feces during raffinose administration are investigated at the species level by using fluorescence in situ hybridization (FISH) coupled with flow cytometry (FCM) analysis. The results have provided a clear demonstration of the population dynamics of indigenous bifidobacteria at the species level in response to raffinose administration.

Phylogenetic analysis of bacteria preserved in a permafrost ice wedge for 25,000 years

Article Abstract:

The cultivation and molecular techniques are used for the phylogenetic analysis of bacteria preserved within an ice wedge from the Fox permafrost tunnel in order to determine the radiocarbon age of the ice wedge. The results have shown that the bacteria in the ice wedge adapted to the frozen conditions have survived for 25,000 years.

Modulation of rat Cecal microbiota by administration of Raffinose and encapsulated Bifidobacterium breve

Article Abstract:

A study was conducted on the effects of administration of raffinose and encapsulated Bifidobacterium breve JCM cells on the rat cecal microbiota. It was observed that the first clear picture of the changes in the rat cecal microbiota was provided in response to symbiotic administration.
