Ruminococcus

Meaning

Ruminococcus is a genus of anaerobic bacteria that constitutes a significant component of the human and animal gut microbiota, belonging to the phylum Firmicutes. These bacteria are primarily known for their crucial role as cellulolytic organisms, meaning they possess the enzymatic machinery to degrade complex polysaccharides like cellulose from dietary fiber. The presence and abundance of Ruminococcus species are important indicators of gut health and metabolic function, influencing the production of short-chain fatty acids. Their role is central to the host’s ability to extract energy from plant matter.
