Methanobacterium limaniae sp. nov. and Methanocella ebodensis sp. nov.

This Register List documents the genome-based description of two novel methanogenic archaeal species, Methanobacterium limaniae sp. nov. and Methanocella ebodensis sp. nov., in accordance with the SeqCode. Both taxa are represented by high-quality genome sequences recovered from enrichment cultures derived from arid desert biocrusts. Phylogenomic analyses place these lineages as distinct species within the genera Methanobacterium and Methanocella, respectively, clearly separated from all previously described taxa. These organisms expand the known ecological and genomic diversity of methanogens inhabiting oxic and desiccation-prone terrestrial environments.
