A novel bacterial strain, YC6899T, was isolated from the root of Suaedae maritima growing on a tidal flat of Namhae Island, Korea. Cells were Gram-reaction-negative, rod-shaped, non-motile, slightly halophilic and heterotrophic. Strain YC6899T grew optimally at a salinity of 2–4 %, at 25–37 °C and at pH 6.5–8.0. Phylogenetic analysis of 16S rRNA gene sequences demonstrated that strain YC6899T was closely related to Amorphus orientalis YIM D10T (96.1 % similarity) and Amorphus coralli RS.Sph.026T (95.9 %). The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, unknown aminolipids, an unknown aminophospholipid, an unknown aminoglycolipid, unknown glycolipids and unknown lipids. The major fatty acids of strain YC6899T were C19 : 0 cyclo ω8c and C18 : 1ω7c. The G+C content of the genomic DNA was 61.3 mol%. Strain YC6899T contained ubiquinone-10 (Q-10) as the major respiratory quinone system. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain YC6899T represents a novel species within the genus Amorphus , for which the name Amorphus suaedae sp. nov. is proposed. The type strain is YC6899T ( = KACC 14912T = NBRC 107845T).

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.

Two Gram-negative, aerobic, rod-shaped bacteria, designated strains SW104T and X07, were isolated from a seawater sample collected from the Indian Ocean. The strains grew at a temperature range of 12–50 °C (optimum, 35–37 °C), and at pH 6.0–9.0 (optimum pH 7.0–7.5). The predominant cellular fatty acids of strain SW104T were iso-C15 : 0 (41.2 %), iso-C17 : 1ω9c (15.2 %) and iso-C17 : 0 (11.1 %). The major respiratory quinone was ubiquinone 8 (Q-8). The major polar lipids were phosphatidylethanolamine, diphosphatidylglycerol and phosphatidylglycerol. The genomic DNA G+C contents of strains SW104T and X07 were 49.8 and 49.5 mol%, respectively. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the new isolates were related to members of the genus Idiomarina , showing the highest similarity with Idiomarina taiwanensis PIT1T and Idiomarina maritima 908087T (96.1 and 95.9 %, respectively). On the basis of phenotypic, genotypic and phylogenetic characteristics, it is proposed that strains SW104T and X07 should be described as representatives of a novel species of the genus Idiomarina , for which the name Idiomarina indica sp. nov. is proposed. The type strain is SW104T ( = CGMCC 1.10824T = JCM 18138T).

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 novel species of Fe(III)-reducing bacterium, designated strain OSK6T, belonging to the genus Geobacter , was isolated from lotus field mud in Japan. Strain OSK6T was isolated using a solid medium containing acetate, Fe(III)-nitrilotriacetate (NTA) and gellan gum. The isolate is a strictly anaerobic, Gram-negative, motile, straight rod-shaped bacterium, 0.6–1.9 µm long and 0.2–0.4 µm wide. The growth of the isolate occurred at 20–40 °C with optima of 30–37 °C and pH 6.5–7.5 in the presence of up to 0.5 g NaCl l−1. The G+C content of the genomic DNA was determined by HPLC to be 59.7 mol%. The major respiratory quinone was MK-8. The major fatty acids were 16 : 1ω7c and 16 : 0. Strain OSK6T was able to grow with Fe(III)-NTA, ferric citrate, amorphous iron (III) hydroxide and nitrate, but not with fumarate, malate or sulfate as electron acceptors. Among examined substrates grown with Fe(III)-NTA, the isolate grew on acetate, lactate, pyruvate and succinate. Analysis of the near full-length 16S rRNA gene sequence revealed that strain OSK6T is closely related to Geobacter daltonii and Geobacter toluenoxydans with 95.6 % similarity to the type strains of these species. On the basis of phylogenetic analysis and physiological tests, strain OSK6T is described as a representative of a novel species, Geobacter luticola sp. nov.; the type strain is OSK6T ( = DSM 24905T = JCM 17780T).

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).
