TonB-dependent transporters (TBDTs) are present in all gram-negative bacteria and
mediate energy-dependent uptake of molecules that are too scarce or large to be taken up …

Background Marine microalgae (phytoplankton) mediate almost half of the worldwide
photosynthetic carbon dioxide fixation and therefore play a pivotal role in global carbon …

During intestinal inflammation, host nutritional immunity starves microbes of essential
micronutrients, such as iron. Pathogens scavenge iron using siderophores, including …

Members of the Bacteroidetes phylum in the human colon deploy an extensive number of
proteins to capture and degrade polysaccharides. Operons devoted to glycan breakdown …

Bacteroidota are abundant members of the human gut microbiota that shape the enteric
landscape by modulating host immunity and degrading dietary-and host-derived glycans …

Abstract Laminarin, a β (1, 3)‐glucan, serves as a storage polysaccharide in marine
microalgae such as diatoms. Its abundance, water solubility and simple structure make it an …

This review evaluates the therapeutic effects of polysaccharides derived from mushroom
species that have medicinal and edible properties. The fungal polysaccharides were …

The impact of therapeutic interventions on the human gut microbiota (GM) is a clinical issue
of paramount interest given the strong interconnection between microbial dynamics and …

Bacteroidales (syn. Bacteroidetes) are prominent members of the human gastrointestinal
ecosystem mainly due to their efficient glycan-degrading machinery, organized into gene …

Mixed-linkage β (1, 3)/β (1, 4)-glucan (MLG) is abundant in the human diet through the
ingestion of cereal grains and is widely associated with healthful effects on metabolism and …
