Metagenome-Assembled Genome of a Putative Methanogenic Methanosarcina sp. Strain Enriched from Terrestrial High-CO ₂ Subsurface Sediments

Abstract

A metagenome-assembled genome (MAG), named Methanosarcina sp. strain ERenArc_MAG2, was obtained from a 3-month-old H 2 /CO 2 atmosphere enrichment culture, originally inoculated with 60-m deep drill core sediment collected from the tectonic Eger Rift terrestrial subsurface. Annotation of the recovered draft genome revealed putative archaeal methanogenesis genes in the deep biosphere.
