Gut flora (gut microbiota, or gastrointestinal microbiota) is the complex community of microorganisms that live in the digestive tracts of humans and other animals, including insects. The gut metagenome is the aggregate of all the genomes of gut microbiota. The gut is one niche that human microbiota inhabit.
As in hind-gut fermentation, microbes in the rumen produce sugars and short-chain fatty acids during the digestion of cellulose - these are the principal source of energy for the ruminant. However, the same microbes also synthesize vitamins, detoxify plant poisons, and recycle nitrogenous compounds into proteins - all actions which help the microbes survive.
