phylogenetic analysis of 18 thermophilic Methanobacterium isolates supports the proposals to create a new genus methanothermobacter gen nov and to reclassify several isolates in three species methanothermobacter thermautotrophicus comb nov methanothe
International Journal of Systematic and Evolutionary Microbiology, 2000Co-Authors: A Wasserfallen, P Pfister, Jork Nolling, J Reeve, Conway E De MacarioAbstract:Using a combination of 16S rRNA analysis and antigenic fingerprinting consisting of new and published data, the phylogenetic position of 18 thermophilic isolates currently classified as Methanobacterium species was reinvestigated. The results were verified by independent methods, including, where applicable, plasmid and phage typing. Comparative analysis of 16S rRNA data for 30 strains belonging to the order Methanobacteriales strongly suggested that mesophilic and thermophilic Methanobacterium isolates are distantly related and should be assigned to separate genera. For the thermophilic strains the genus Methanothermobacter was initially proposed by Boone, Whitman and Rouviere. Furthermore, the results support a reclassification of 15 isolates in three species within the proposed genus: (i) Methanothermobacter thermautotrophicus comb. nov., containing eight isolates, six of which are able to utilize formate (type strain deltaHT); (ii) Methanothermobacter wolfeii comb. nov., containing four formate-utilizing isolates (type strain DSM 2970T); (iii) Methanothermobacter marburgensis sp. nov., containing three obligately autotrophic isolates (type strain MarburgT). Of the nine isolates formerly referred to as Methanobacterium thermoformicicum, six were reclassified as Methanothermobacter thermautotrophicus and three as Methanothermobacter wolfeii.

Methanobacterium arcticum sp nov a methanogenic archaeon from holocene arctic permafrost
International Journal of Systematic and Evolutionary Microbiology, 2011Co-Authors: V A Shcherbakova, Elizaveta Rivkina, S A Pecheritsyna, Kestus Laurinavichius, Nataliya E Suzina, David GilichinskyAbstract:A mesophilic, non-motile, hydrogenotrophic, rod-shaped methanogen, designated M2T, was isolated from Holocene permafrost sediments of the Kolyma lowland in the Russian Arctic. Cells were 3–6 μm long and 0.45–0.5 μm wide. Strain M2T grew on H2/CO2 and formate. Optimum conditions for growth were 37 °C, pH 6.8–7.2 and 0.1 M NaCl. The DNA G+C content was 38.1 mol%. On the basis of 16S rRNA gene sequence comparison with known methanogens, strain M2T was affiliated with the genus Methanobacterium and was most closely related to Methanobacterium veterum MK4T and Methanobacterium bryantii DSM 863T (both 99 % 16S rRNA gene sequence similarity). However, no significant DNA–DNA relatedness was observed between strain M2T and these type strains. We propose that strain M2T represents a novel species, with the name Methanobacterium arcticum sp. nov., with type strain M2T (=DSM 19844T =VKM B-2371T).

Methanobacterium veterum sp nov from ancient siberian permafrost
International Journal of Systematic and Evolutionary Microbiology, 2010Co-Authors: Kirill Krivushin, V A Shcherbakova, L E Petrovskaya, Elizaveta RivkinaAbstract:A methanogenic archaeon, strain MK4T, was isolated from ancient permafrost after long-term selective anaerobic cultivation. The cells were rods, 2.0–8.0 μm long and 0.40–0.45 μm wide, and stained Gram-negative. Optimal growth was observed at 28 °C and pH 7.0–7.2 and in 0.05 M NaCl. The isolate used H2 plus CO2, methylamine plus H2 and methanol plus H2 as sources for growth and methanogenesis. Phylogenetic analysis of the 16S rRNA gene sequence of the strain showed close affinity with Methanobacterium bryantii (similarity >99 % to the type strain). On the basis of the level of DNA–DNA hybridization (62 %) between strain MK4T and Methanobacterium bryantii VKM B-1629T and phenotypic and phylogenetic differences, strain MK4T was assigned to a novel species of the genus Methanobacterium, Methanobacterium veterum sp. nov., with the type strain MK4T (=DSM 19849T =VKM B-2440T).

Methanobacterium veterum sp. nov., from ancient Siberian permafrost.
International journal of systematic and evolutionary microbiology, 2009Co-Authors: Kirill Krivushin, V A Shcherbakova, L E Petrovskaya, Elizaveta RivkinaAbstract:A methanogenic archaeon, strain MK4(T), was isolated from ancient permafrost after long-term selective anaerobic cultivation. The cells were rods, 2.0-8.0 microm long and 0.40-0.45 microm wide, and stained Gram-negative. Optimal growth was observed at 28 degrees C and pH 7.0-7.2 and in 0.05 M NaCl. The isolate used H(2) plus CO(2), methylamine plus H(2) and methanol plus H(2) as sources for growth and methanogenesis. Phylogenetic analysis of the 16S rRNA gene sequence of the strain showed close affinity with Methanobacterium bryantii (similarity >99 % to the type strain). On the basis of the level of DNA-DNA hybridization (62 %) between strain MK4(T) and Methanobacterium bryantii VKM B-1629(T) and phenotypic and phylogenetic differences, strain MK4(T) was assigned to a novel species of the genus Methanobacterium, Methanobacterium veterum sp. nov., with the type strain MK4(T) (=DSM 19849(T) =VKM B-2440(T)).
