Ethan ist mit einem Anteil von bis zu zehn Prozent der zweithäufigste Bestandteil von Erdgas und in tiefen Gaslagerstätten im terrestrischen und marinen Bereich weltweit vorhanden. Ungeklärt war bislang, wie Ethan unter sauerstofffreien Bedingungen abgebaut wird. Ein Team von Forschenden des Helmholtz-Zentrums für Umweltforschung (UFZ) hat nun gemeinsam mit Kollegen des Max-Planck-Instituts für Marine Mikrobiologie in Bremen nach mehr als fünfzehn Jahren Forschungsarbeit dieses Rätsel gelöst. In Sedimentproben des Golfs von Mexiko haben die Wissenschaftlerinnen und Wissenschaftler in einer mikrobiellen Gemeinschaft ein Archaeon nachgewiesen, das Ethan oxidiert. Dem einzelligen Organismus gaben sie den vorläufigen Namen CandidatusArgoarchaeum ethanivorans, was so viel bjdfqqjq vkr ysvldrb eudxqbxmad Pslzwfwnjvmb.
