The methane periodically gusts forth from grazing herds in the form of rumbling postprandial belches. But if cattle contribute to the global methane load, they are hardly alone. Swamps, termite mounds and rice paddies are all hosts to similar sorts of bacterial methane factories...

Vitamin D, for example, is manufactured in the skin during exposure to sunlight, and three other vitamins (K, biotin and pantothenic acid) are made inside the human gut by resident bacteria. But most vitamins must be ingested...

This organism's genome consists of approximately one million base pairs of DNA. The bacteria is one of a group of "Model organisms" which are being sequenced along with the human genome to discover new techniques of DNA analysis as well as to acquire knowledge about the organism itself...
