The acquisition and assimilation strategies followed by members of the infant gut microbiota to retrieve nitrogen from the gut lumen are still largely unknown. In particular, no information on these metabolic processes is available regarding bifidobacteria, which are among the first microbial colonizers of the human intestine. Here, evaluation of amino acid auxotrophy and prototrophy of Bifidob...

Probiotic ice cream was made by fermenting a standard ice cream mix with Lactobacillus acidophilus and Bifidobacterium bifidum cultures and then freezing the mix in a batch freezer. Survival of the L. acidophilus and B. bifidum, as well as beta-galactosidase activity, was monitored during 17 wk of frozen storage at -29 degrees C. After freezing of the fermented mix, bacterial counts were 1.5 x ...

Background: Cancer is amongst the leading reasons of death in all parts of the world. Breast cancer is also responsible for the largest number of deaths among women population. Several studies confirmed that Bifidobacterium bifidum as a probiotic meaningfully inhibited breast cancer development. The present study aimed to investigate the effect of B. bifidum supernatant on the cell growth inhib...

Bifidobacterium bifidum is one of the most frequently found bifidobacteria in the intestines of newborn infants. We previously reported that B. bifidum possesses unique metabolic pathways for O-linked glycans on gastrointestinal mucin (Yoshida E, Sakurama H, Kiyohara M, Nakajima M, Kitaoka M, Ashida H, Hirose J, Katayama T, Yamamoto K, Kumagai H. 2012. Bifidobacterium longum subsp. infantis use...

A healthy intestinal microbiota is considered to be important for priming of the infants' mucosal and systemic immunity. Breast-fed infants typically have an intestinal microbiota dominated by different Bifidobacterium species. It has been described that allergic infants have different levels of specific Bifidobacterium species than healthy infants. For the accurate quantification of Bifidobact...

Uma dieta saudável pode incluir a ingestão de bebidas com componentes que modulem beneficamente microbiota intestinal, resultando no aumento bactérias probióticas como as pertencentes aos gêneros Lactobacillus e Bifidobacterium. O objetivo do trabalho foi verificar in vitro influência diferentes origens da bebida café exercem sobre taxa sobrevivência acidophilus LA 3 Bifidobacterium bifidum em ...

Polyphenols are a common group of plant based bioactive compounds, that can affect human health because of their antioxidant and antimicrobial properties as well as free-radical scavenging activity. An increasing interest is observed in the interaction between polyphenols and microbiota occurring in food and the human gut. The aim of the work presented here, was to evaluate the effect of some p...

Bifidobacteria are Gram-positive inhabitants of the human gastrointestinal tract that have evolved close interaction with their host and especially with the host's immune system. The molecular mechanisms underlying such interactions, however, are largely unidentified. In this study, we investigated the immunomodulatory potential of Bifidobacterium bifidum MIMBb75, a bacterium of human intestina...

BACKGROUND Radiation-induced diarrhea is frequently observed during pelvic radiotherapy. This study was performed to determine the ability of a probiotic containing live lactobacillus acidophilus plus bifidobacterium bifidum to reduce the incidence of radiation-induced diarrhea in locally advanced cervical cancer patients. METHODS Patients who were undergoing pelvic radiotherapy concurrent wi...

Soy-based foods are rich in high quality proteins, essential amino acids, minerals, vitamins etc. thus they provide a range of health benefits. In this study, growth and α-galactosidase activity of bifidobacteria (Bifidobacterium lactis Bb-12, B. longum Bb-46, B. bifidum B3.2, B. bifidum B7.1 and B. breve B9.14) were investigated. All tested bifidobacteria strains showed αgalactosidase activity...
