A novel cherry-red-pigmented, Gram-stain-negative, gliding, facultatively anaerobic and rod-shaped bacterium, designated strain WTE16T, was isolated from a sediment sample taken from a marine solar saltern of Wendeng, China (36° 59′ 56.49′′ N 122° 1′ 38.84′′ E). The novel isolate was able to grow at 20–40 °C (optimum 33 °C), at pH 6.0–9.0 (optimum pH 7.0) and with 1.0–12.0 % (w/v) NaCl (optimum 3.0–5.0 %). Phylogenetic analysis based on 16S rRNA gene sequences indicated that the most closely related validly published species is Marinilabilia salmonicolor JCM 21150T (96.0 % similarity). Average nucleotide identity, average amino acid identity, percentage of conserved proteins and digital DNA–DNA hybridization values between strain WTE16T and Marinilabilia salmonicolor JCM 21150T were 73.8 %, 73.5 %, 63.4 % and 19.5–24.2 %, respectively. The genomic DNA G+C content of strain WTE16T was 40.8 mol%. Chemotaxonomic analysis showed that the sole respiratory quinone was menaquinone 7 (MK-7), and the major fatty acids included iso-C15 : 0 and anteiso-C15 : 0. The polar lipid profile of strain WTE16T included phosphatidylethanolamine, three unidentified phospholipids and three unidentified lipids. On the basis of its phylogenetic, phenotypic, chemotaxonomic, genotypic and genomic characteristics, strain WTE16T is suggested to represent a novel species of the genus Marinilabilia , for which the name Marinilabilia rubra sp. nov. is proposed. The type strain is WTE16T (=KCTC 62599T=MCCC 1H00311T).

A novel Gram-stain-negative, non-endospore-forming, motile, and aerobic bacterial strain, M105T, was isolated from coral Porites lutea, and was subjected to a polyphasic taxonomic study. Global alignment based on 16S rRNA gene sequences indicated that M105T shares the highest sequence identity of 94.5 % with Aliikangiella marina GYP-15T. The average nucleotide identity (ANI) and average amino acid identity (AAI) between M105T and A. marina GYP-15T was 69.8 and 71.6 %, respectively. On the basis of the results of phenotypic, chemotaxonomic, phylogenetic, phylogenomic, and comparative genomic analyses, it is concluded that M105T should represent a novel species in the genus Aliikangiella , for which the name Aliikangiella coralliicola sp. nov. is proposed. The type strain is M105T (=MCCC 1K03773T= KCTC 72442T). Furthermore, the family Kangiellaceae was classified into two families on the basis of phylogenetic, phylogenomic, polar lipid profile and motility variations. The novel family Pleioneaceae fam. nov. is proposed to accommodate the genera Aliikangiella and Pleionea .

The newly identified bacterial strain grew optimally in modified Reasoner's 2A medium under the following conditions: 0 % (w/v) NaCl, pH 7.5 and 35 °C. Phylogenetic analysis using the 16S rRNA gene sequence confirmed that strain NIBR12T belongs to the genus Roseococcus , with its closest neighbours being Roseococcus suduntuyensis SHETT (98.8%), Roseococcus thiosulfatophilus RB-3T (97.7%), “Sediminicoccus rosea” R-30T (95.7 %) and Rubritepida flocculans H-8T (95.0 %). Genomic comparison of strain NIBR12T with type species in the genus Roseococcus was conducted using digital DNA–DNA hybridization, average nucleotide identity and average amino acid identity analyses, resulting in values of ≤53.7, ≤93.7 and ≤96.1 %, respectively. The genomic DNA G+C content of strain NIBR12T was 70.9 mol%. The major fatty acids of strain NIBR12T were summed feature 8 (C18 : 1  ω7c and/or C18:1 ω6c) and summed feature 3 (C16 : 1 ω6c/C16 : 1 ω7c). Q-9 was its major respiratory quinone. Moreover, the major polar lipids of strain NIBR12T were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and phosphatidylcholine. Based on our chemotaxonomic, genotypic and phenotype analyses, strain NIBR12T is identified as represeting a novel species of the genus Roseococcus , for which the name Roseococcus microcysteis sp. nov. is proposed.

A bacterial strain, designated Dd16T, was isolated from a hexachlorocyclohexane (HCH) dumpsite at Lucknow, India. Cells of strain Dd16T were Gram-stain-negative, non-motile, rod-shaped and yellow-pigmented. Phylogenetic analysis based on 16S rRNA gene sequences showed that the strain belonged to the genus Sphingomonas in the family Sphingomonadaceae , as it showed highest sequence similarity to Sphingomonas asaccharolytica IFO 15499T (95.36 %), Sphingosinicella vermicomposti YC7378T (95.30), ‘Sphingomonas humi’ PB323 (95.20 %), Sphingomonas sanxanigenens NX02T (95.14 %) and Sphingomonas desiccabilis CP1DT (95.00 %). The major fatty acids were summed feature 3 (C16 : 1ω7c/C16 : 1ω6c) C14 : 0 2-OH, summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c) and C16 : 0. The polar lipid profile of strain Dd16T also corresponded to those reported for species of the genus Sphingomonas (phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol, and a sphingoglycolipid), again supporting its identification as a member of the genus Sphingomonas . The predominant respiratory quinone was ubiquinone Q10, and sym-homospermidine was the major polyamine observed. The total DNA G+C content of strain Dd16T was 65.8 mol%. The results obtained on the basis of phenotypic characteristics and phylogenetic analysis and after biochemical and physiological tests, clearly distinguished strain Dd16T from closely related members of the genus Sphingomonas . Thus, strain Dd16T represents a novel species of the genus Sphingomonas for which the name Sphingomonas indica sp. nov. is proposed. The type strain is Dd16T ( = DSM 25434T = CCM 7882T).

A cream-coloured, Gram-stain-negative, rod-shaped bacterium, designated strain KSC-6T, was isolated from soil sampled at the Gapcheon River watershed in Daejeon, Republic of Korea. The organism does not require NaCl for growth and grows at pH 6.0–8.0 (optimum, pH 7.0) and 10–37 °C (optimum, 25 °C). Phylogenetic trees based on the 16S rRNA gene sequences reveal that strain KSC-6T belongs to the family Chitinophagaceae within the order Chitinophagales and is most closely related to Panacibacter ginsenosidivorans Gsoil 1550T (95.9% similarity). The genomic DNA G+C content was 38.9 mol%. The major cellular fatty acids (>8 %) of strain KCS-6T were iso-C15:0, iso-C15 : 1 G and iso-C17 : 0 3-OH. The predominant respiratory quinone was menaquinone 7 and the predominant polar lipids were phosphatidylethanolamine, five unidentified aminolipids and two unidentified lipids. Based on genome analyses, low digital DNA–DNA hybridization, average nucleotide identity and average amino acid identity values with closely related genera, and differential chemotaxonomic and physiological properties, we suggest that strain KCS-6T represents a novel species in a new genus in the family Chitinophagaceae , for which the name Limnovirga soli gen. nov., sp. nov. (type strain KCS-6T=KCCM 43337T=NBRC 114336T) is proposed.

Taxonomic Approach

A bacterial strain, designated NSW-5T, was isolated from a water sample taken from Niao-Song Wetland Park in Taiwan and characterized using a polyphasic taxonomic approach. Cells of strain NSW-5T were strictly aerobic, Gram-stain-negative, non-motile and polymorphic, being straight, vibrioid, curved and spiral-shaped rods surrounded by a thick capsule and forming light pink-coloured colonies. Some rings consisting of several cells were present. Growth occurred at 10–40 °C (optimum, 25 °C), with 0–3.0 % NaCl (optimum, 0 %) and at pH 6.0–8.0 (optimum, pH 7.0). Phylogenetic analyses based on 16S rRNA gene sequences showed that strain NSW-5T belonged to the genus Arcicella with sequence similarities of 98.6, 98.0 and 97.3 % with Arcicella aquatica NO-502T, Arcicella rosea TW5T and Arcicella aurantiaca TNR-18T, respectively. The predominant cellular fatty acids were summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c; 20.8 %), C16 : 0 (14.6 %), iso-C15 : 0 (13.8 %), C16 : 1ω5c (12.5 %) and C18 : 0 (11.4 %), and the only respiratory quinone was MK-7. The polar lipid profile consisted of phosphatidylethanolamine and several uncharacterized glycolipids, aminolipids, phospholipids and aminophospholipids. The DNA G+C content of strain NSW-5T was 44.1 mol%. The DNA–DNA relatedness of strain NSW-5T with respect to recognized species of the genus Arcicella was less than 70 %. On the basis of phylogenetic inference and phenotypic data, strain NSW-5T should be classified as a representative of a novel species, for which the name Arcicella rigui sp. nov. is proposed. The type strain is NSW-5T ( = KCTC 23307T = BCRC 80260T). Emended descriptions of the genus Arcicella and of Arcicella aquatica , Arcicella rosea and Arcicella aurantiaca are also proposed.

The Gram-strain-negative, rod-shaped, facultatively anaerobic, non-motile bacterial strain, designated S1-10T, was isolated from marine sediment. Strain S1-10T grew at 4–42 °C (optimally at 30–35 °C), at pH 7.0–10 (optimally at pH 9) and in the presence of 0.5–8 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain S1-10T was related to the genus Aequorivita and had highest 16S rRNA gene sequence similarity to Aequorivita viscosa 8-1bT (97.7%). The predominant cellular fatty acids were iso-C15 : 0 and anteiso-C15 : 0. The main respiratory quinone was menaquinone 6 (MK-6). The genomic DNA G+C content of strain S1-10T was 34.6 mol%. The polar lipid profile of strain S1-10T contained phosphatidylethanolamine, two aminolipids, two glycolipids, one phosphoglycolipid and three unidentified polar lipids. In addition, the maximum values of in silico DNA–DNA hybridization (isDDH) and average nucleotide identity (ANI) between strain S1-10T and A. viscosa CGMCC 1.11023T were 15.4 and 75.7 %, respectively. Combined data from phenotypic, phylogenetic, isDDH and ANI analyses demonstrated that strain S1-10T is the representative of a novel species of the genus Aequorivita , for which we propose the name Aequorivita sinensis sp. nov. (type strain S1-10T=CGMCC 1.12579T=JCM 19789T). We also propose that Vitellibacter todarodis and Vitellibacter aquimaris should be transferred into genus Aequorivita and be named Aequorivita todarodis comb. nov. and Aequorivita aquimaris comb. nov., respectively. The type strain of Aequorivita todarodis comb. nov. is MYP2-2T (= KCTC 62141T= NBRC 113025T) and the type strain of Aequorivita aquimaris comb. nov. is D-24T (=KCTC 42708T=DSM 101732T).
