Abstract

Methanococcoides methylutens, the type species of the genus Methanococcoides, is a slightly halophilic methanogenic archaeon with a methylotrophic metabolism. Here, we present the annotated draft genome sequence of M. methylutens, which comprises 2,508,511 bp with 2,482 coding sequences, 51 tRNA genes, and a G+C content of 42.5%.

Highlights

  • Methanococcoides methylutens, the type species of the genus Methanococcoides, is a slightly halophilic methanogenic archaeon with a methylotrophic metabolism

  • Together with several other strains closely related to M. methylutens, that is, MM1 [5], NaT1 [6], MO-MCD [7], AM1, DM1, NM1, PM1, and PM2 [8], Methanococcoides species have been cultivated from anoxic hypolimnion of Ace Lake and various sediment environments such as marine, mangrove, and mud volcanoes

  • We announce the genome sequence of M. methylutens as a basis for future comparative studies aimed at understanding the ecological niche of this genus

Summary

Introduction

Methanococcoides methylutens, the type species of the genus Methanococcoides, is a slightly halophilic methanogenic archaeon with a methylotrophic metabolism. The genus Methanococcoides currently comprises four described and characterized species: M. methylutens [1], M. burtonii [2], M. alaskense [3], and M. vulcani [4]. M. methylutens is the type species of this genus that was isolated from submarine canyon sediments off the coast of southern California [1]. Together with several other strains closely related to M. methylutens, that is, MM1 [5], NaT1 [6], MO-MCD [7], AM1, DM1, NM1, PM1, and PM2 [8] (with 16S rRNA gene identities of 98% to 99%), Methanococcoides species have been cultivated from anoxic hypolimnion of Ace Lake and various sediment environments such as marine, mangrove, and mud volcanoes.
