Acute psychological stress is positively associated with a cold/flu. The present randomised, double-blind, placebo-controlled study examined the effect of three potentially probiotic bacteria on the proportion of healthy days over a 6-week period in academically stressed undergraduate students (n 581) who received Lactobacillus helveticus R0052, Bifidobacterium longum ssp. infantis R0033, Bifid...

In this work, we report the genome sequences of Bifidobacterium bifidum strain LMG13195. Results from our research group show that this strain is able to interact with human immune cells, generating functional regulatory T cells.

In this study, we report the first completely annotated genome sequence of the Russian-origin Bifidobacterium longum subsp. longum strain GT15. We discovered 35 unique genes (UGs) which were detected from only the B. longum GT15 genome and were absent from other B. longum strain genomes (not of Russian origin).

Bifidobacterium longum RD47 was cultured in 24 kinds of modified MRS broths containing various ingredients to select the most promising source that induces microbial enzymes. Among the various ingredients, ascorbic acid significantly enhanced α-l-arabinofuranosidase and α-l-arabinopyranosidase activities in Bifidobacterium longum RD47. Addition of 2 % ascorbic acid (w/v) to MRS showed the maxim...

Several strains belonging to the genus Bifidobacterium were tested to determine their abilities to produce succinic acid. Bifidobacterium longum strain BB536 and Bifidobacterium animalis subsp. lactis strain Bb 12 were kinetically analyzed in detail using in vitro fermentations to obtain more insight into the metabolism and production of succinic acid by bifidobacteria. Changes in end product f...

INTRODUCTION Probiotics have demonstrated potential to reduce duration of diarrhoea and frequency of watery stools. Probiotics such as Lactobacillus acidophilus and Bifidobacterium bifidum (Infloran(®)) are usually maintained at a storage temperature of 4°C which is generally not feasible in tropical or sub-tropical countries. AIM The efficacy of Infloran(®) for treatment of acute diarrhoea w...

Bifidobacterium aesculapii DSM 26737(T) was isolated from feces of baby common marmoset. Here, we report the draft genome sequence of this organism. This paper is the first published report of the genomic sequence of B. aesculapii.

in fermented products containing bifidobacteria, factors such as organic acid concentration and b-galactosidase activity are important in the development of flavor and texture of final products. both the process conditions and medium components have significant effects on fluctuation of such factors. the effects of whey permeate powder and yeast extract concentrations, as nitrogen sources was i...
