Adhesion, autoaggregation and hydrophobicity of 13 strains of Bifidobacterium longum

Adhesion properties of a putative polymorphic fimbrial subunit protein from Bifidobacterium longum subsp. longum

In our previous study, we found that the open reading frame bl0675 in the genome of Bifidobacterium longum subsp. longum isolated from human feces encoded a novel putative fimbrial protein, was highly polymorphic, and had five variants (A, B, C, D, and E types). The aim of this study was to evaluate the affinity of these variants to porcine colonic mucins (PCMs). Protein-binding properties were...

Bioaccessible Antioxidants in Milk Fermented by Bifidobacterium longum subsp. longum Strains

Bifidobacterium longum subsp. longum is among the dominant species of the human gastrointestinal microbiota and could thus have potential as probiotics. New targets such as antioxidant properties have interest for beneficial effects on health. The objective of this study was to evaluate the bioaccessibility of antioxidants in milk fermented by selected B. longum subsp. longum strains during in ...

Complete Genome Sequence of Bifidobacterium longum GT15: Unique Genes for Russian Strains

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).

Transcriptome analysis of Bifidobacterium longum strains that show a differential response to hydrogen peroxide stress.

Consumer and commercial interest in foods containing probiotic bifidobacteria is increasing. However, because bifidobacteria are anaerobic, oxidative stress can diminish cell viability during production and storage of bioactive foods. We previously found Bifidobacterium longum strain NCC2705 had significantly greater intrinsic and inducible resistance to hydrogen peroxide (H2O2) than strain D29...
