A Gram-staining-negative, aerobic, yellow, non-flagellated, non-gliding, rod-shaped bacterium, designated strain IMCC1021T, was isolated off the coast of the East Sea. Optimal growth of strain IMCC1021T was observed at 25 °C, pH 7.0–7.5 and in the presence of 3.0–3.5 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the strain belonged to the genus Mesonia , showing a close relationship with Mesonia mobilis KMM 6059T (97.4 % similarity) followed by Mesonia phycicola MDSW-25T (96.1 %). DNA–DNA relatedness between strain IMCC1021T and M. mobilis KMM 6059T was 17.5 % (reciprocal 7.4 %), which indicated that the new isolate represents a novel genomic species of the genus Mesonia . The major fatty acids were iso-C15 : 0 and iso-C17 : 0 3-OH, and the G+C content of the genomic DNA was 41.4 mol%. Strain IMCC1021T contained menaquinone-6 (MK-6) as the respiratory quinone, and polar lipids comprising phosphatidylethanolamine, two unknown aminolipids and three unknown polar lipids. On the basis of the phylogenetic distinctions and differential phenotypic characteristics, it is suggested that strain IMCC1021T ( = KCTC 32320T = NBRC 109485T) should be assigned to the genus Mesonia as the type strain of a novel species, for which the name Mesonia aquimarina sp. nov. is proposed.

A Gram-staining-negative, chemoheterotrophic, yellow-pigmented, non-motile, flexirubin-negative, facultatively anaerobic bacterium, designated strain IMCC3317T, was isolated from a coastal seawater sample from the Antarctic Penninsula. Optimal growth of strain IMCC3317T was observed at 20 °C, pH 8.0 and in the presence of 2–3 % NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain IMCC3317T belonged to the genus Kordia and was closely related to Kordia algicida OT-1T (96.7 % sequence similarity) and Kordia periserrulae IMCC1412T (96.1 % sequence similarity). The major fatty acids were 10-methyl C16 : 0 and/or iso-C16 : 1ω9c, iso-C17 : 0 3-OH, iso-C15 : 0 and anteiso-C15 : 0. The G+C content of the genomic DNA was 35.1 mol%. The strain contained menaquinone-6 (MK-6) as the respiratory quinone. The polar lipids detected in the strain were phosphatidylethanolamine and unknown aminophospholipids, aminolipids and polar lipids. On the basis of phylogenetic distinction and differential phenotypic characteristics, it is suggested that strain IMCC3317T ( = KCTC 32292T = NBRC 109401T) be assigned to the genus Kordia as the type strain of a novel species, for which the name Kordia antarctica sp. nov. is proposed.

A strictly anaerobic, mesophilic, iron-reducing bacterial strain, IRF19T, was isolated from coal-contaminated soil in the Republic of Korea. IRF19T cells were straight, rod-shaped, Gram-staining-negative and motile by means of flagella. The optimum pH and temperature for their growth were determined to be pH 7.5–8.0 and 40 °C, while the optimum range was pH 6.5–10.0 and 20–45 °C, respectively. Strain IRF19T did not require NaCl for growth but it tolerated up to 2 % (w/v). Growth was observed with yeast extract, d-glucose, d-fructose, d-ribose, d-mannitol, d-mannose, l-serine, l-alanine and l-isoleucine. Fe(III), elemental sulfur, thiosulfate and sulfate were used as electron acceptors. Phylogenetic analysis based on the 16S rRNA gene sequences indicated that strain IRF19T is affiliated to the family Clostridiaceae and is most closely related to Salimesophilobacter vulgaris Zn2T (93.5 % similarity), Geosporobacter subterraneus VNs68T (93.2 %) and Thermotalea metallivorans B2-1T (92.3 %). The major cellular fatty acids of strain IRF19T were C14 : 0, iso-C15 : 0 and C16 : 0, and the profile was distinct from those of the closely related species. The major respiratory quinone of strain IRF19T was menaquinone MK-5 (V-H2). The main polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, an unknown phospholipid and two unknown polar lipids. The G+C content of the genomic DNA of strain IRF19T was determined to be 37.4 mol%. On the basis of phenotypic, chemotaxonomic and phylogenetic results, strain IRF19T is considered to represent a novel species of a novel genus of the family Clostridiaceae , for which we propose the name Anaerosolibacter carboniphilus gen. nov., sp. nov., with the type strain IRF19T ( = KCTC 15396T = JCM 19988T).
