From: Methanogenic Archaea Can Produce Methane in Deliquescence-Driven Mars Analog Environments

Methane content in the headspace observed as proxi for metabolic activity in the Closed Deliquescence System during the course of the experiment: M. soligelidi was tested in P-MRA with 30 wt% NaCl at 4 °C for 64 days (n = 3, SEM).
