Propionate is observed to be among the most common short-chain fatty acids produced by human gut microbiota in response to indigestible carbohydrates (fiber) in the diet. A study in mice suggests that propionate is produced by the bacteria of the genus Bacteroides in the gut, and that it offers some protection against Salmonella there.
