The federally funded field study, published online in the journal Science, offers peer-reviewed evidence that naturally occurring microbes in the Gulf devoured significant amounts of toxic chemicals in natural gas and oil spewing from the seafloor, which researchers had thought would persist in the region’s water chemistry for years.

“Within a matter of months, the bacteria completely removed that methane,”said microbiologist David Valentine at the University of California at Santa Barbara. “The bacteria kicked on more effectively than we expected,” he said.
