Abstract

Paper published in Scientific Reports reporting the biosignature potential of Martian methane by assessing the viability of hydrogenotrophic methanogenesis in Methanosarcina barkeri MS under simulated Martian surface conditions of sustained hypobaria (7-12 mbar), low temperature (0°C), and a CO2-dominated gas mixture mimicking the Martian atmosphere.
