Selective human milk oligosaccharide utilization by members of the taxon.
Appl Environ Microbiol

Article Synopsis
- Human milk oligosaccharides (HMOs) are not digested by infants but help promote beneficial bacteria like bifidobacteria in their gut.
- The study explored how 23 newly isolated bifidobacterial strains grow on specific HMOs, identifying key genes connected to their metabolism, especially through a strain named MM0196.
- The research enhances our understanding of HMOs' role in gut health for infants, suggesting potential benefits for probiotic applications and improved infant nutrition, possibly extending to adults.
Bifidobacteria are commonly encountered members of the human gut microbiota that possess the enzymatic machinery necessary for the metabolism of certain plant-derived, complex carbohydrates. In the current study we describe differential growth profiles elicited by a panel of 21 newly isolated strains on various plant-derived glycans. Using a combination of gene-trait matching and comparative genome analysis, we identified two distinct xylanases responsible for the degradation of xylan.

Lactic acid bacteria are naturally found in raw vegetables, being Lactiplantibacillus plantarum the most commonly used commercial starter for the fermentation of plant foods.

This complex microbial community has developed many metabolic strategies to colonize, persist and survive in the gastrointestinal environment. In this regard, intracellular glycogen accumulation has been associated with important physiological functions in several bacterial species, including gut commensals.

- Antibiotic resistance is a major global issue, particularly affecting newborns whose developing immune systems make them more susceptible to infections from multidrug-resistant microorganisms.
- Factors like the delivery method, mother's antibiotic history, and early-life antibiotic use can influence a newborn's gut microbiota and the spread of antibiotic resistance.
- This review highlights the need for more research on the transmission of antibiotic-resistant genes from mothers to infants, particularly through breastmilk, and aims to identify gaps in knowledge to help devise better strategies to combat this public health threat.
