variation 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 subsp. longum and bifidobacterium breve isolates tested appear less adapted to these substrates. conside ...201323892749
Identification of iron-regulated genes of Bifidobacterium breve UCC2003 as a basis for controlled gene expression.Iron is an essential growth factor for virtually all organisms. However, iron is not readily available in most environments and microorganisms have evolved specialized mechanisms, such as the use of siderophores and high-affinity transport systems, to acquire iron when confronted with iron-limiting conditions. In general these systems are tightly regulated to prevent iron-induced toxicity and because they are quite costly to the microbe. Because of this tight regulation we chose to explore the r ...201222179149
