This bacterium produces methane in human guts. Normal humans fart about 10 - 15 times per day, passing a few hundred milliliters of gas per day. Boys and girls fart about the same amount. Though over 50 percent of this gas is nitrogen, some of the gas is microbially produced, including the gas methane, which is flammable and is also a powerful greenhouse gas. Carbohydrates that cannot be digested by humans, but can be digested by microbes, are the leading cause of farts. Methane is an odorless gas: smells come from dimethyl sulfide and methanethiol. Other gases include oxygen, hydrogen, carbon dioxide, and nitrogen.
