lachnospiraceae lachnospiraceae the lachnospiraceae are a family of obligately anaerobic, variably spore-forming bacteria in the order eubacteriales that ferment diverse plant polysaccharides to short-chain fatty acids (butyrate, acetate) and alcohols (ethanol). these bacteria are among the most abundant taxa in the rumen and the human gut microbiota. members of this family may protect against colon cancer in humans by producing butyric acid. lachnospiraceae have been found to contribute to diabetes in genetically susceptible (ob/ob) germ-free mice. lachnospiraceae scientific classification domain: bacteria phylum: bacillota class: clostridia order: eubacteriales family: lachnospiraceaerainey 2010 genera abyssivirga acetatifactor acetitomaculum agathobacter anaerobium anaerobutyricum anaerocolumna anaerosacchariphilus anaerostipes anaerotaenia anaerotignum blautia butyrivibrio catenibacillus catonella cellulosilyticum coprococcus cuneatibacter dorea eisenbergiella enterocloster extibacter faecalicatena faecalimonas falcatimonas frisingicoccus fusicatenibacter herbinix hespellia howardella johnsonella kineothrix lachnoanaerobaculum lachnobacterium lachnoclostridium lachnospira lachnotalea lacrimispora marvinbryantia mediterraneibacter merdimonas mobilisporobacter mobilitalea moryella muricomes murimonas natranaerovirga oribacterium parasporobacterium pseudobutyrivibrio robinsoniella roseburia schaedlerella sellimonas shuttleworthia sporobacterium sporofaciens stomatobaculum syntrophococcus
