A novel Gram-staining-negative, moderately halophilic and strictly aerobic bacterium, designated strain 112T, was isolated from a tidal flat at Taean, Korea. Cells were catalase- and oxidase-positive ovoids to rods and did not produce bacteriochlorophyll a. Optimum growth of strain 112T was observed at 30 °C, at pH 6.5–7.5 and in the presence of 2–4 % (w/v) NaCl. The major cellular fatty acids were summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c) and C16 : 0 and Q-10 was detected as the predominant ubiquinone. The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, an unidentified aminolipid and three unidentified lipids. The genomic DNA G+C content of strain 112T was 58.2 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain 112T formed a phyletic lineage within the genus Roseovarius of the class Alphaproteobacteria . Strain 112T was most closely related to Roseovarius mucosus DFL-24T, with 96.52 % similarity. On the basis of phenotypic, chemotaxonomic and molecular properties, strain 112T represents a novel species of the genus Roseovarius , for which the name Roseovarius lutimaris sp. nov. is proposed. The type strain is 112T ( = KACC 16185T = JCM 17743T).

A Gram-staining-positive, aerobic, motile bacterium, designated strain MJ3T, was isolated from myeolchi-jeot (anchovy jeotgal), a traditional fermented seafood in South Korea. Cells were non-endospore-forming cocci showing catalase- and oxidase-positive reactions. Growth of strain MJ3T was observed at 15–45 °C (optimum, 30 °C), at pH 6.0–9.0 (optimum, pH 7.0–8.0) and in the presence of 1–24 % (w/v) NaCl (optimum, 10 % NaCl). Phylogenetic inference based on 16S rRNA gene sequences showed that strain MJ3T formed a tight phyletic lineage with members of the genus Salimicrobium . Strain MJ3T was related most closely to Salimicrobium salexigens 29CMIT, Salimicrobium album DSM 20748T, Salimicrobium flavidum ISL-25T, Salimicrobium luteum BY-5T and Salimicrobium halophilum DSM 4771T, with similarities of 98.8 %, 98.7 %, 98.6 %, 98.4 % and 98.3 %, respectively. However, the DNA–DNA relatedness values between strain MJ3T (KF732837) and S. salexigens DSM 22782T, S. album DSM 20748T, S. flavidum DSM 23127T, S. luteum KCTC 3989T and S. halophilum JCM 12305T were 60±5.4 %, 58.5±6.5 %, 43.6±5.5 %, 37.2±5.8 % and 16.7±0.2 %, respectively. Chemotaxonomic data (sole isoprenoid quinone, MK-7; major cell-wall type, meso-diaminopimelic acid; major cellular fatty acids, anteiso-C15 : 0, anteiso-C17 : 0 and iso-C15 : 0; major polar lipids, phosphatidylglycerol and diphosphatidylglycerol; DNA G+C content, 46.3 mol%) also supported the affiliation of strain MJ3T with the genus Salimicrobium . Therefore, strain MJ3T represents a novel species of the genus Salimicrobium , for which the name Salimicrobium jeotgali sp. nov. is proposed. The type strain is MJ3T ( = KACC 16972T = JCM 19758T).

A novel actinomycete strain, designed MW4-36T, was isolated from tropical forest soil in Nakhon Sawan Province, Thailand. Morphological and chemotaxonomic characteristics of this strain clearly demonstrated that it belongs to the genus Dactylosporangium . The strain formed finger-shaped sporangia on short sporangiophores that emerged directly from substrate hyphae. The cell-wall peptidoglycan contained glutamic acid, glycine, alanine and meso-diaminopimelic acid including 3-hydroxy-meso-diaminopimelic acid; arabinose, glucose, rhamnose, ribose and xylose were found as whole-cell sugars. The diagnostic phospholipids were phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol and phosphatidylinositol; no phosphatidylcholine was found. The predominant menaquinones were MK-9(H8) and MK-9(H6). Mycolic acids were not detected. The predominant cellular fatty acids were iso-C15 : 0, iso-C16 : 0, anteiso-C15 : 0 and anteiso-C17 : 0. The G+C content of the genomic DNA was 72.9 mol%. Phylogenetic analysis based on 16S rRNA gene sequences also indicated that the strain should be classified in the genus Dactylosporangium and showed that the closest relative was Dactylosporangium maewongense JCM 15933T (99.4 % similarity). These taxonomic data revealed that strain MW4-36T could be readily distinguished from its phylogenetically closest relative. On the basis of these phenotypic and genotypic data, strain MW4-36T is considered to represent a novel species, for which the name Dactylosporangium siamense sp. nov. is proposed. The type strain is MW4-36T ( = BCC 34901T = NBRC 106093T).

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.
