Lachnospiraceae
The Lachnospiraceae are a family of anaerobic, spore-forming bacteria in the order Clostridiales that ferment diverse plant polysaccharides to short-chain fatty acids and alcohols. 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 cause diabetes in germ-free mice.
