Family of bacteria-like microbes that produce methane.
Methanobacteriaceae are methane-producing, bacteria-like microbes that play an important role in the gut ecosystem by facilitating carbohydrate fermentation and production of short-chain fatty acids by commensal bacteria. [L]
Facilitates carbohydrate fermentation and short-chain fatty acid production by beneficial bacteria.
High levels linked to chronic constipation, as well as some types of SIBO and IBS. Low levels may indicate reduced production of short-chain fatty acids and may be associated with inflammation.

Reduced levels have been found in patients with inflammatory bowel disease.
Low levels may indicate reduced production of short-chain fatty acids and may be associated with inflammation.
