In order to persist, successful bacterial inhabitants of the human gut need to adapt to
changing nutrient conditions, which are influenced by host diet and a variety of other factors …

Obesity and diabetes have reached epidemic proportions. Evidence suggests that besides
dietary habits and physical activity, other environmental factors, such as gut microbes, are …

In the human gut microbiota, Bacteroidetes break down dietary and endogenous glycosides
through highly specific polysaccharide utilization loci (PULs). PULs encode a variety of …

The human gut contains trillions of microorganisms that play a central role in many aspects
of host biology, including the provision of key nutrients from the diet. However, our …

Symbiotic bacteria are responsible for the majority of complex carbohydrate digestion in the
human colon. Since the identities and amounts of dietary polysaccharides directly impact the …

The critical importance of gastrointestinal microbes to digestion of dietary fiber in humans
and other mammals has been appreciated for decades. Symbiotic microorganisms expand …

The complex carbohydrates of terrestrial and marine biomass represent a rich nutrient
source for free-living and mutualistic microbes alike. The enzymatic saccharification of these …

The human digestive system is host to a highly populated ecosystem of bacterial species
