A Gram-staining-negative, strictly aerobic, motile (by gliding), non-spore-forming and rod-shaped bacterial strain, designated THG-DT86T, was isolated from soil of a ginseng field of Pocheon province in the Republic of Korea and its taxonomic position was investigated by a polyphasic approach. Growth occurred at 10–35 °C, at pH 6.5–8.5 and with 0–1.5 % (w/v) NaCl on trypticase soy agar. Flexirubin-type pigments were found to be present. On the basis of 16S rRNA gene sequence similarity, strain THG-DT86T was shown to belong to the genus Taibaiella and was related to Taibaiella smilacinae PTJT-5T (95.3 %). The G+C content of the genomic DNA was 50.1 mol%. The only isoprenoid quinone detected in strain THG-DT86T was menaquinone-7 (MK-7) and the only polyamine was homospermidine. The predominant fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH, C16 : 0, iso-C15 : 1 G and iso-C17 : 0, and the major polar lipids were phosphatidylethanolamine, an unidentified aminophosphoglycolipid and an unidentified aminophospholipid. Phenotypic data and phylogenetic inference supported the affiliation of strain THG-DT86T to the genus Taibaiella , and a number of biochemical tests differentiated strain THG-DT86T from the recognized species of the genus Taibaiella . Therefore, the novel isolate represents a novel species, for which the name Taibaiella koreensis sp. nov. is proposed, with THG-DT86T as the type strain ( = KACC 17171T = JCM 18823T).

An autotrophic, hydrogenotrophic methanogen, designated strain 17A1T, was isolated from the profundal sediment of the meromictic Lake Pavin, France. The cells of the novel strain, which were non-motile, Gram-staining-negative rods that measured 2–15 µm in length and 0.2–0.4 µm in width, grew as filaments. Strain 17A1T grew in a mineral medium and its growth was stimulated by the addition of yeast extract, vitamins, acetate or rumen fluid. Penicillin, vancomycin and kanamycin reduced growth but did not completely inhibit it. Growth occurred at 14–41 °C (optimum 30 °C), at pH 5.0–8.5 (optimum pH 6.5) and with 0–0.4 M NaCl (optimum 0.1 M). The novel strain utilized H2/CO2 and methanol/H2 as substrates but not formate, acetate, methylamine/H2, isobutanol or 2-propanol. Its genomic DNA G+C content was 37.0 mol%. In phylogenetic analyses based on 16S rRNA gene sequences, strain 17A1T appeared to be a member of the genus Methanobacterium , with Methanobacterium beijingense 8-2T (96.3 % sequence similarity) identified as the most closely related established species. Based on phenotypic and phylogenetic data, strain 17A1T represents a novel species of methanogen within the genus Methanobacterium , for which the name Methanobacterium lacus sp. nov. is proposed. The type strain is 17A1T ( = DSM 24406T = JCM 17760T).
