A Gram-reaction-negative, aerobic, yellowish-orange-pigmented bacterial strain, designated JC2436T, was isolated from tidal-flat sediment of Oi Island in Korea. Comparative 16S rRNA gene sequence analysis indicated its close affiliation to Vitellibacter vladivostokensis, with 96 % sequence similarity to the type strain. Cells grew with 2–6 % NaCl and at 10–41 °C. Orange flexirubin pigments were present. The major isoprenoid quinone was MK-6, the DNA G+C content was 48.7 mol% and the predominant fatty acids (>10 %) were iso-C15 : 0 and iso-C17 : 0 3-OH. The data obtained from this polyphasic study support the classification of this isolate within a novel species in the genus Vitellibacter, for which the name Vitellibacter aestuarii sp. nov. is proposed. The type strain is JC2436T (=IMSNU 14137T =KACC 13727T =KCTC 22361T =JCM 15496T).

A Gram-stain-negative, facultatively anaerobic, rod-shaped (1.8–4.4×0.5–0.7 µm) and motile marine bacterium, designated as MEBiC13590T, was isolated from tidal flat sediment sampled at Incheon City, on the west coast of the Republic of Korea. The 16S rRNA gene sequence analysis revealed that strain MEBiC13590T showed high similarity to Oricola cellulosilytica CC-AMH-0T (98.2 %), followed by Oceaniradius stylonematis StC1T (97.5 %); however, it clustered with Oricola cellulosilytica . The phylogenomic tree inferred by the up-to-date bacterial core gene set suggested that strain MEBiC13590T shared a phyletic line with Oricola cellulosilytica . Average nucleotide identity and digital DNA–DNA hybridization values (75.0 and 19.3 %, respectively) between strain MEBiC13590T and Oricola cellulosilytica CC-AMH-0T were below the respective species delineation cutoffs. Growth was observed at 22–50 °C (optimum, 45 °C), at pH 5–9 (optimum, pH 7) and with 1–6 % (optimum, 3 %) NaCl. The predominant cellular fatty acids were C16 : 0 (7.6 %), C18 : 0 (12.2 %), 11-methyl C18 : 1 ω7c (5.7 %), C19 : 0 cyclo ω6c and summed feature 8 (comprising C18 : 1 ω7c and/or C18 : 1 ω6c; 38 %). The DNA G+C content was 63.5 mol%. The major respiratory quinone was Q-10. Several phenotypic characteristics such as growth temperature, oxygen requirement, enzyme activities of urease, gelatinase, lipase (C14), α-chymotrypsin, acid phosphatase, β-galactosidase, β-glucosidase etc. differentiate strain MEBiC13590T from Oricola cellulosilytica CC-AMH-0T. Based on this polyphasic taxonomic data, strain MEBiC13590T should be classified as representing a novel species in the genus Oricola for which the name Oricola thermophila sp. nov. is proposed . The type strain is MEBiC13590T (=KCCM 43313T=JCM 33661T).

A Gram-reaction-negative, chemoheterotrophic, non-motile, facultatively anaerobic, curved rod-shaped bacterial strain, IMCC4453T, was isolated from tidal flat sediment and subjected to a taxonomic study using a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain IMCC4453T belonged to the genus Saccharospirillum, forming a robust clade with members of the genus, and was most closely related to the type strains of Saccharospirillum salsuginis (97.6 % similarity) and Saccharospirillum impatiens (95.9 %). The DNA–DNA relatedness value between strain IMCC4453T and S. salsuginis YIM-Y25T was 23–30 %. Differences in several physiological and biochemical characteristics between strain IMCC4453T and the two recognized species of the genus Saccharospirillum, together with phylogenetic and genomic distinctiveness, differentiated the novel strain from members of the genus Saccharospirillum. On the basis of the data from the present study, it is concluded that strain IMCC4453T represents a novel species of the genus Saccharospirillum, for which the name Saccharospirillum aestuarii sp. nov. is proposed. The type strain is IMCC4453T (=KCTC 22684T=KCCM 42930T=NBRC 105825T). An emended description of the genus Saccharospirillum is provided.

A Gram-staining-negative, aerobic and moderately halophilic bacterium, designated strain NS6T, was isolated from sea-tidal-flat sediment of the South Sea in Korea. Cells were motile rods with a single flagellum showing positive catalase and oxidase activities. Strain NS6T grew at 15–40 °C (optimum, 30 °C), at pH 6.0–9.0 (optimum, pH 7.0–7.5) and in the presence of 1–5 % (w/v) NaCl (optimum, 2 %). Ubiquinone-10 was identified as the only isoprenoid quinone and summed feature 8 (comprising C18 : 1ω7c/ω6c), C19 : 0 cyclo ω8c, C16 : 0 and C10 : 0 3-OH were the major fatty acids. Strain NS6T contained phosphatidylglycerol, sulfoquinovosyldiacylglycerol, an unidentified amino lipid and an unidentified lipid as the major polar lipids. An unidentified phospholipid and three unidentified lipids were also detected as the minor polar lipids. The G+C content of the genomic DNA was 64.5 mol%. Strain NS6T was most closely related to Confluentimicrobium lipolyticum SSK1-4T with a 96.8 % 16S rRNA gene sequence similarity, and the phylogenetic analysis based on 16S rRNA gene sequences showed that strain NS6T formed a tight phylogenetic lineage with C. lipolyticum SSK1-4T. The physiological, chemotaxonomic and phylogenetic properties suggest that strain NS6T represents a novel species of the genus Confluentimicrobium, for which the name Confluentimicrobium naphthalenivorans sp. nov. is proposed. The type strain is NS6T ( = KCTC 18418T = JCM 30828T). An emended description of the genus Confluentimicrobium is also proposed.

The 16S Rrna Gene

A Gram-negative-staining, aerobic, non-motile and rod-shaped bacterial strain, S5-5T, was isolated from a tidal flat sediment at Saemankum on the west coast of Korea and subjected to a polyphasic taxonomic investigation. Strain S5-5T grew optimally at pH 7.5–8.0, at 30 °C and in the presence of 2 % (w/v) NaCl. It did not produce bacteriochlorophyll a. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain S5-5T is phylogenetically closely related to the genus Roseivivax, joining the cluster comprising the two recognized Roseivivax species. The 16S rRNA gene sequence similarity between strain S5-5T and members of the genus Roseivivax was in the range 95.0–96.7 %. Strain S5-5T contained Q-10 as the predominant ubiquinone and C18 : 1 ω7c and 11-methyl C18 : 1 ω7c as the major fatty acids. The DNA G+C content was 68.2 mol%. Differential phenotypic properties, together with the phylogenetic distinctiveness, demonstrated that strain S5-5T could be differentiated from Roseivivax species. On the basis of the data presented, strain S5-5T is considered to represent a novel species of the genus Roseivivax, for which the name Roseivivax lentus sp. nov. is proposed. The type strain is S5-5T (=KCTC 22708T =CCUG 57755T).

A Gram-negative, non-spore-forming, non-motile rod, designated MA-My1T, was isolated from a tidal flat sediment of the South Sea, Korea. Strain MA-My1T grew optimally at pH 7.0–7.5, at 30 °C and with 2.0–3.0 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain MA-My1T clustered with Lutibacter litoralis CL-TF09T and Lutibacter maritimus S7-2T, with which it exhibited 97.3 and 95.3 % 16S rRNA gene sequence similarity, respectively. Strain MA-My1T contained MK-6 as the predominant menaquinone and iso-C15 : 0, iso-C15 : 0 3-OH and iso-C16 : 0 3-OH as the major fatty acids. The major polar lipids were phosphatidylethanolamine and two unidentified lipids. The DNA G+C content was 30.6 mol% and DNA–DNA relatedness between strain MA-My1T and L. litoralis JCM 13034T was 6.3±0.8 %. The differential phenotypic properties, together with phylogenetic and genotypic distinctiveness, distinguished strain MA-My1T from the members of the genus Lutibacter. On the basis of the data presented, strain MA-My1T is considered to represent a novel species of the genus Lutibacter, for which the name Lutibacter aestuarii sp. nov. is proposed. The type strain is MA-My1T ( = KCTC 23499T  = CCUG 60022T).
