The bacteria, a member of the genus Halomonadaceae, live in California's Mono Lake, amidst concentrations of arsenic that would kill most other life forms.
Research led by a NASA astrobiologist in 2010 that suggested the existence of bacteria could grow using arsenic instead of phosphorus has been challenged by two new studies.
The new studies refute a December 2010 finding that, if confirmed, would have revolutionized how we think about life.
Scientists have found a microbe in Mono Lake, California, that uses arsenic as a fundamental building block, changing the definition of 'life as we know it' and the search for extraterrestrial life.
