Summary

A newly identified Arctic Ocean bacterium may have an unusual way of making the building blocks it needs to grow. Using acetone, a common chemical in seawater, the bacteria incorporate carbon dioxide (CO₂) into their metabolisms, allowing them to survive in waters where nutrients and usable organic matter are scarce. In a study published in Nature Communications , Concordia researchers describe how Porticoccus arcticus survives in the frigid waters of the Beaufort Sea, just north of the Yukon in the Arctic Ocean's Canada Basin.
