Lachnospiraceae

The Lachnospiraceae are a family of obligately anaerobic, variably spore-forming bacteria in the order Eubacteriales that ferment diverse plant polysaccharides^[3] to short-chain fatty acids (butyrate, acetate) and alcohols (ethanol). These bacteria are among the most abundant taxa in the rumen^[4] and the human gut microbiota.^[5][6][7][8] Members of this family may protect against colon cancer in humans by producing butyric acid.^[9][10] Lachnospiraceae have been found to contribute to diabetes in genetically susceptible (ob/ob) germ-free mice.^[11]
