Abstract

Bifidobacteria are a genus of beneficial microbes that colonize in the human gastrointestinal tract. A critical feature of this genus is their ability to metabolize a variety of carbohydrates encountered in the gastrointestinal tract, including oligosaccharides. The central fermentative pathway unique to bifidobacteria is known as the bifid shunt and is employed to generate ATP following scavenging of carbohydrates. The bifidobacteria have evolved efficient molecular mechanisms to acquire and metabolize carbohydrates in order to successfully compete with other members of the microbiota. This chapter summarizes what is currently understood about the nutritional requirements and the metabolism of environmental substrates that contribute to biomass and ATP production.
