Ability of Bifidobacterium breve to grow on different types of milk: exploring the metabolism of milk through genome analysis.

چکیده
We have investigated the occurrence of bifidobacteria in human milk samples, and we provide evidence regarding the predominance of members of the Bifidobacterium breve species in this environment. Moreover, evaluation of the growth capabilities and transcriptomic analyses of one representative isolate of this species, i.e., B. breve 4L, on different milk types were performed.

Complete genome sequence of Bifidobacterium breve CECT 7263, a strain isolated from human milk.
Bifidobacterium breve is an actinobacterium frequently isolated from colonic microbiota of breastfeeding babies. Here, we report the complete and annotated genome sequence of a B. breve strain isolated from human milk, B. breve CECT 7263. The genome sequence will provide new insights into the biology of this potential probiotic organism and will allow the characterization of genes related to be...
متن کاملVariation in consumption of human milk oligosaccharides by infant gut-associated strains of Bifidobacterium breve.
Human milk contains a high concentration of complex oligosaccharides that influence the composition of the intestinal microbiota in breast-fed infants. Previous studies have indicated that select species such as Bifidobacterium longum subsp. infantis and Bifidobacterium bifidum can utilize human milk oligosaccharides (HMO) in vitro as the sole carbon source, while the relatively few B. longum s...

Background: Intestinal colonization of the newborn is essential for establishment, maturation and maintenance of the gut mucosal barrier. The greatest difference between the microbiota of breast milk and Infant formula infants feeding is the numbers and species composition of Bifidobacteria. In this study, we tried to identify the native Bifidobacterium isolates obtained from the human’s breast...
متن کاملThe Effect of Coffee Extract on the Growth and Viability of Lactobacillus acidophilus and Bifidobacterium bifidum in Probiotic Milk and Yoghurt
The aim of this study was to determine the suitability of different doses (0, 0.4, 0.8 and 1.2%) of coffee extract on fermentation and survival of Lactobacillus acidophilus and Bifidobacterium bifidum in milk and yoghurt. The produced samples were examined in terms of pH, acidity and microbial count during incubation period and permanence. The number of Lactobacillus acidophilus and Bifidobacte...
متن کاملBifidobacterium breve UCC2003 metabolises the human milk oligosaccharides lacto-N-tetraose and lacto-N-neo-tetraose through overlapping, yet distinct pathways
In this study, we demonstrate that the prototype B. breve strain UCC2003 possesses specific metabolic pathways for the utilisation of lacto-N-tetraose (LNT) and lacto-N-neotetraose (LNnT), which represent the central moieties of Type I and Type II human milk oligosaccharides (HMOs), respectively. Using a combination of experimental approaches, the enzymatic machinery involved in the metabolism ...
