Lachnospiraceae is a family of predominantly obligately anaerobic bacteria in the order Eubacteriales. Members of the family are common in the digestive tracts of mammals, including the rumen and the human gut microbiota. Many members ferment carbohydrates and produce short-chain fatty acids, including acetate and butyrate.[2]

Lachnospiraceae constituted the largest family represented in the Hungate1000 collection of cultured rumen microorganisms. Genomic analysis of the collection identified members with genes involved in the degradation of cellulose, hemicellulose, pectin, and other polysaccharides.[3]

Changes in the abundance and composition of Lachnospiraceae have been reported in studies of human disease, including colorectal cancer.[4] Colonization by a particular Lachnospiraceae strain also promoted diabetes in genetically obese germ-free mice, although such findings do not necessarily apply uniformly across this taxonomically diverse family.[5]

Taxonomy

The type genus is Lachnospira.[1] LPSN places Lachnospiraceae in the order Eubacteriales, whereas the Genome Taxonomy Database places it in the order Lachnospirales.[6]
