  • Our work demonstrates the existence of a potential xanthan gum food chain involving at least two members of different phyla of gut bacteria and provides an initial framework for understanding how widespread consumption of a recently introduced food additive influences human microbiomes. (nature.com)
  • Based on the number of carbon atoms, a carbohydrate can be classified as triose (3 C), tetrose (4 C), pentose (5 C), and hexose (6 C). The suffix " ose " at the end of a biochemical name flags the molecule as a "sugar. (oregonstate.education)

  • All plants and animals, from simple life forms to humans, live in close association with microbial organisms. (wikipedia.org)
  • Here we show that the ability to digest xanthan gum is common in human gut microbiomes from industrialized countries and appears contingent on a single uncultured bacterium in the family Ruminococcaceae. (nature.com)
  • Fructose, or "fruit sugar," is found in ripened fruits and honey and is also formed by digestion of disaccharide sucrose. (oregonstate.education)

  • For microbial organisms, recent evidence from genomes recovered from metagenomic samples corroborate a highly complex view of their metabolic diversity and other associated traits which map into high physiological complexity. (bvsalud.org)
  • Since they derive energy from fermentation (a chemical conversion of carbohydrates to ethanol and carbon dioxide ), yeasts are found primarily in sugar -rich environments, such as fruit surfaces or flower nectars. (newworldencyclopedia.org)
