—Formate Energizes Microbes “Some species of archaea can survive with only formate providing for their energy needs” Some species of single-celled organisms called archaea can survive with only formate providing their energy needs, reports an international group led by Jung-Hyun Lee and Sung Gyun Kang of the Korea Ocean Research & Development Institute (Nature 2010, 467, 352). The work builds on a finding two years ago by Jan Dolfing and coworkers at Wageningen University, in the Netherlands, that communities of bacteria and archaea, each of which performed a different function, could also live off formate. Kim and colleagues determined that certain species of the Thermococcus genus of archaea survive by converting formate (HCOO–) to CO2 and H 2 and then coupling that reaction to adenosine triphosphate (ATP) synthesis.
