Polyphasic Characterization

Strain M2T, isolated from marine sediment collected at Jeju Island, was an aerobic, Gram-stain-negative, oxidase- and catalase-positive, motile, rod-shaped bacterium that formed circular, raised, yellow colonies. Strain M2T grew at 15–42 °C, pH 5.5–9.0 and with 1–9 % (w/v) NaCl. Phylogenetic analysis based on its 16S rRNA gene sequences indicated that strain M2T was closely related to Kineobactrum sediminis F02T (98.0 % sequence similarity). Ubiquinone-8 was determined to be the sole respiratory quinone. Summed feature 3 (C16 : 1  ω6c/C16 : 1  ω7c) and summed feature 8 (C18 : 1  ω7c/C18 : 1  ω6c) were identified as the predominant fatty acids. The DNA G+C content and digital DNA–DNA relatedness between strain M2T and K. sediminis F02T were 60.7 mol% and 19.5 %, respectively. Phosphatidylglycerol and phosphatidylethanolamine were identified as the major polar lipids. Thus, polyphasic characterization revealed that strain M2T represents a novel species in the genus Kineobactrum , for which the name Kineobactrum salinum sp. nov. is proposed. The type strain is M2T (=KCTC 72815T=VTCC 910108T).

A Gram-negative bacterium, designated DCY13T, was isolated from soil of a ginseng field in South Korea. Comparative analysis of 16S rRNA gene sequences showed that strain DCY13T shared the highest sequence similarity (95.0 %) with Sediminibacterium salmoneum NBRC 103935T and 87.6–91.4 % sequence similarity with other members of the family Chitinophagaceae . Cells were non-spore-forming rods, catalase- and oxidase-positive, motile by gliding and facultatively anaerobic. The only respiratory quinone was menaquinone 7 (MK-7) and the major fatty acids were iso-C17 : 0 3-OH, iso-C15 : 0 and iso-C15 : 1 G. The G+C content of the genomic DNA was 47.5±1.0 mol%. In addition to phosphatidylethanolamine, the major polar lipids were two unidentified aminophospholipids, one unidentified aminolipid and three unidentified polar lipids. The major cell-wall sugars were ribose, xylose and galactose. It is proposed that strain DCY13T represents a novel species in the genus Sediminibacterium , for which the name Sediminibacterium ginsengisoli sp. nov. is proposed. The type strain is DCY13T ( = KCTC 12833T  = JCM 15794T  = DSM 22335T). Emended descriptions of the genus Sediminibacterium and of Sediminibacterium salmoneum are also proposed.

Comparative genome analysis between strain KIS59-12T and A. rhizosphaerae Vu-144T showed that average nucleotide identity value was 69.4 % and the digital DNA–DNA hybridization value was 19.1 %. The major respiratory quinone was menaquinone-7. The major polar lipids were phosphatidylethanolamine and an unknown polar lipid. The predominant cellular fatty acids were iso-C15 : 0, iso-C15 : 1 G and iso-C17 : 0 3-OH, which supported the affiliation of strain KIS59-12T with the genus Arachidicoccus . The major polyamines were homospermidine and putrescine. The genomic DNA G+C content was 36.4 mol%. On the basis of phylogenetic, physiological and chemotaxonomic characteristics, strain KIS59-12T represents a novel species of the genus Arachidicoccus , for which the name Arachidicoccus soli sp. nov. is proposed. The type strain of Arachidicoccus soli is KIS59-12T (=KACC 17340T=NBRC 113161T).

A Gram-stain-negative, non-motile and aerobic bacterium, designated CF17T, was isolated from coastal planktonic seaweeds, East China Sea. The isolate grew at 18–37 °C (optimum 25–28 °C), pH 6.5–9.0 (optimum 7.0–8.0) and with 0–5 % NaCl (optimum 1–2 %, w/v) and 0.5–10 % sea salts (optimum 2–3 %, w/v). Growth of strain CF17T could be stimulated prominently by supplementing the growth medium with the autoclaved supernatant of a culture of strain CF5, which was isolated from the same sample along with strain CF17T. The cell morphology of strain CF17T was a bean-shaped rod consisting of a swollen end and a long prostheca. The phylogenetic analysis of 16S rRNA gene sequences indicated that strain CF17T clustered with Gemmobacter nectariphilus DSM 15620T within the genus Gemmobacter . The DNA G+C content of strain CF17T was 61.4 mol%. The respiratory quinone was ubiquinone Q-10. The major fatty acids included C18 : 1ω7c and C18 : 0. The polar lipids of strain CF17T consisted of phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, two uncharacterized phospholipids, one uncharacterized aminolipid, three uncharacterized glycolipids and one uncharacterized lipid. On the basis of phenotypic, phylogenetic and chemotaxonomic data, strain CF17T ( = CGMCC 1.11024T = JCM 18498T) is considered to represent a novel species of the genus Gemmobacter , for which the name Gemmobacter megaterium sp. nov. is proposed.

A non-motile and rod-shaped bacterium, designated strain 02SUJ3T, was isolated from freshwater collected from the Juam Reservoir (Republic of Korea). Cells were Gram-stain-negative, aerobic, oxidase-negative and catalase-positive. The major fatty acids were iso-C15 : 0, iso-C15 : 1 G and iso-C17 : 0 3-OH. The strain contained MK-7 as the major isoprenoid quinone. The main polar lipid was phosphatidylethanolamine. The DNA G+C content was 46.4 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain 02SUJ3T forms an independent lineage within the genus Flavisolibacter with low sequence similarity to Flavisolibacter ginsengiterrae Gsoil 492T and Flavisolibacter ginsengisoli Gsoil 643T (95.7 %). Phenotypic characteristics distinguished strain 02SUJ3T from members of the genus Flavisolibacter . On the basis of the evidence presented in this study, strain 02SUJ3T is considered to represent a novel species, for which the name Flavisolibacter rigui sp. nov. is proposed.

A novel Gram-staining-negative, coccoid, non-motile bacterium, designated strain V1-41T, was isolated from a sample of marine sediment collected, at a depth of 200 m, from Kongsfjorden (an inlet on the west coast of Spitsbergen, an island that forms part of the Svalbard archipelago in the Arctic Ocean). The strain formed cream–brown colonies on marine agar. Cells of the novel strain were positive in tests for catalase, oxidase, lysine decarboxylase and ornithine decarboxylase activities but negative for gelatinase and lipase activities. They hydrolysed aesculin, starch and urea, but not casein or DNA. Most of the cellular fatty acids were medium-chain and saturated (37.1 %) or long-chain and unsaturated (27.8 %), with C12 : 0 (37.1 %), C18:1ω7c, and summed features 2 (19.3%) and 3 (24.1%) predominating. The major respiratory quinone was Q-8. The polar lipids consisted of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, two unidentified aminophospholipids, four unidentified phospholipids and one other unidentified lipid. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the novel strain’s closest known relatives were Oceanisphaera litoralis DSM 15406T (98.5 % sequence similarity) and Oceanisphaera donghaensis BL1T (98.3 %). In DNA–DNA hybridizations, however, the levels of relatedness between strain V1-41T and O. litoralis DSM 15406T and between the novel strain and O. donghaensis DSM 17589T were found to be only 19 % and 29 %, respectively. Based on these low levels of similarity at the DNA–DNA level and the phenotypic and chemotaxonomic differences from O. litoralis DSM 15406T and O. donghaensis DSM 17589T, strain V1-41T represents a novel species of the genus Oceanisphaera for which the name Oceanisphaera arctica sp. nov. is proposed. The type strain is V1-41T ( = CCUG 58690T = KCTC 23013T = NBRC 106171T).
