A Gram-staining-negative, rod-shaped and pink bacterium was isolated from the soil of a Populus euphratica forest in the Taklamakan desert, Xinjiang, China. It was designated strain H9XT. A 16S rRNA gene sequence homology search indicated that the isolate was most closely related to the family Cytophagaceae . The 16S rRNA gene of strain H9XT displayed 94.2–96.3 % sequence identities to those of type strains of other species of the genus Pontibacter . It only possessed menaquinone-7. The major cellular fatty acids of the novel isolate were iso-C15 : 0, C16 : 1ω5c summed feature 3 (containing C16 : 1ω6c and/or C16 : 1ω7c) and summed feature 4 (comprising anteiso-C17 : 1 B and/or iso-C17 : 1 I). The major polar lipids were phosphatidylethanolamine, one unknown aminophospholipid, one unknown glycophospholipid and several unknown phospholipids. The DNA G+C content of this bacterium was 55.2 mol%. Based on the phenotypic and genotypic data presented, it can be concluded that this isolate represents a novel species of the genus Pontibacter , for which the name Pontibacter yuliensis sp. nov. is proposed. The type strain is H9XT ( = CCTCC AB 2013047T = KCTC 32396T).

A slow-growing, strictly aerobic, Gram-negative, coccus bacterial strain, designated KAUST100406-0324T, was isolated from sea-floor sediment collected from the Red Sea, Saudi Arabia. The catalase- and oxidase-positive strain was non-sporulating and only slightly halophilic. Optimum growth occurred at 20–25 °C and at pH values ranging from 7.0 to 8.0. The major cellular fatty acids of the strain were unsaturated C18 : 1ω6c and/or C18 : 1ω7c, C18 : 1ω7c 11-methyl and C16 : 1ω7c and/or C16 : 1ω6c. The major polar lipids were phosphatidylglycerol, phosphatidylethanolamine and two unidentified phospholipids. Ubiquinone 10 was the predominant lipoquinone. The DNA G+C content of strain KAUST100406-0324T was 64.0 mol%. Phylogenetic analysis of 16S rRNA gene sequences revealed that the novel strain belonged to the family Rhodobacteraceae of the class Alphaproteobacteria but formed a distinct evolutionary lineage from other bacterial species with validly published names. The 16S rRNA gene sequence of the novel strain was distantly related, but formed a monophyletic cluster with, those of bacteria from two moderately halophilic genera, Hwanghaeicola and Maribius . The similarity of the sequence between the novel strain KAUST100406-0324T and the type strains Hwanghaeicola aestuarii Y26T (accession number FJ230842), Maribius pelagius B5-6T (DQ514326) and Maribius salinus CL-SP27T (AY906863) were 94.5 %, 95.2 % and 95.3 %, respectively. Based on the physiological, phylogenetic and chemotaxonomic characteristics presented in this study, we propose that this strain represents a novel species of a new genus in the family Rhodobacteraceae , for which the name of Profundibacterium mesophilum gen. nov., sp. nov. was proposed, with KAUST100406-0324T ( = JCM 17872T  = NRRL B-59665T) as the type strain.

A Gram-stain-negative, aerobic, motile, orange-pigmented, slightly halophilic, rod-shaped bacterium, designated strain JAMH 0132T, was isolated from the trophosome of a tubeworm in Kagoshima Bay, Japan, and its taxonomic position was investigated using a polyphasic approach. The novel strain grew optimally at 28–30 °C and with about 2.0 % (w/v) NaCl. Chemotaxonomic analysis showed that Q-10 was the predominant respiratory quinone and that C18 : 1ω7c, C16 : 0 2-OH and C16 : 0 were the major fatty acids. Sphingoglycolipid, phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol and phosphatidylcholine were the major polar lipids. The genomic DNA G+C content was 60.1 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain JAMH 0132T belonged to the family Sphingomonadaceae , within the class Alphaproteobacteria . The novel strain appeared most closely related to Sphingopyxis baekryungensis SW-150T (95.1 % 16S rRNA gene sequence similarity) and showed less sequence similarity with representatives of the genera Blastomonas , Sphingomonas , Sphingosinicella and Novosphingobium (<94.8 %). In having no detectable polyamine, strain JAMH 0132T differed from members of all genera currently in the family Sphingomonadaceae . On the basis of its phenotypic properties and phylogenetic distinctiveness, strain JAMH 0132T represents a novel species of a new genus in the family Sphingomonadaceae for which the name Parasphingopyxis lamellibrachiae gen. nov., sp. nov. is proposed. The type strain of Parasphingopyxis lamellibrachiae gen. nov., sp. nov. is JAMH 0132T ( = JCM 15549T  = NCIMB 14486T).

A taxonomic study was carried out on strain GCS-AE-31T, which was isolated from a phenol-degrading consortium, enriched from coking wastewater activated sludge of the Beijing Shougang Company Limited during the screening of phenol-degrading bacteria. Cells of strain GCS-AE-31T were Gram-stain-negative, short rods, motile by gliding, oxidase- and catalase-positive. Growth was observed at salinities of 0–3 % and at temperatures of 10–37 °C. On the basis of 16S rRNA gene sequence similarity, strain GCS-AE-31T was most closely related to Pedobacter saltans LMG 10337T (96.17 %), but it showed low similarity to all other species of the genus Pedobacter (89.28–92.45 %). It also showed low 16S rRNA gene similarity to all other species of the family Sphingobacteriaceae (87.25–92.45 %) examined. The dominant fatty acids were iso-C15 : 0, summed feature 3 (C16 : 1ω7c/C16 : 1ω6c), anteiso-C15 : 0 and iso-C17 : 0 3-OH. The menaquinones were MK-7 (95.5 %) and MK-6 (4.5 %). The polar lipids were phosphatidylethanolamine, three aminolipids and three unknown phospholipids. Sphingolipid was present. The G+C content of the chromosomal DNA was 36.2 mol%. According to its phylogenetic position and phenotypic traits, the novel strain could not be assigned to the genus Pedobacter ; it should be classified as representing a novel species of a novel genus in the family Sphingobacteriaceae , for which the name Pseudopedobacter beijingensis gen. nov., sp. nov. is proposed (type strain GCS-AE-31T = MCCC 1A01299T = CGMCC 1.12329T = LMG 27180T). The misclassified species Pedobacter saltans is transferred to the novel genus as Pseudopedobacter saltans comb. nov. (type strain LMG 10337T = MCCC 1A06472T = DSM 12145T = CCUG 39354T = CIP 105500T = JCM 21818T = NBRC 100064T).

Two Gram-stain-positive, strictly aerobic, non-spore-forming actinobacterial strains, designated YC2-7T and YC5-17, were isolated from the Yongcheondonggul (larva cave) in Jeju, Republic of Korea and their taxonomic ranks were examined by a polyphasic approach. The 16S rRNA gene tree showed that the novel isolates occupied an independent position separated from recognized genera of the family Nocardiaceae . In the 92 core gene-based phylogenomic analysis, strain YC2-7T was loosely associated with the type strain of Aldersonia kummingensis with 66.2 % average amino acid identity. The 16S rRNA gene sequence simairity between the isolate and members of the family Nocardiaceae was below 96.7 %. The cell-wall peptidoglycan was meso-diaminopimelic acid as a diagnostic diamino acid. Whole-cell sugars consisted of arabinose, galactose and glucose. The predominant menaquinone was MK-8(H4, ω-cycl). The major polar lipids consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol and phosphatidylinositol mannoside. The cellular fatty acids consisted mainly of saturated and unsaturated components with small amounts of tuberculostearic acid. Mycolic acids of 52–58 carbon atoms were present. The DNA G+C content of the genome was 63.8 mol%. On the basis of combination of morphological and chemotaxonomic differences, in addition to phylogenetic distinctness, the novel isolates are considered to constitute members of a novel species of a new genus in the family Nocardiaceae , for which the name Antrihabitans stalactiti gen. nov., sp. nov. is proposed. The type strain is YC2-7T (=KACC 19965T=DSM 108733T).

A novel Gram-staining-positive, non-endospore-forming, aerobic bacterium, designated strain SJ5-4T, was isolated from seau-jeot, a traditional food that is made by fermentation of highly salted [approximately 25 % (w/v)] shrimp in Korea. Cells were moderately halophilic, non-motile cocci or short rods that showed catalase- and oxidase-positive reactions. Growth of strain SJ5-4T was observed at 15–40 °C (optimum, 30 °C), at pH 6.0–9.5 (optimum, pH 6.5–7.0) and in the presence of 1–17 % (w/v) NaCl (optimum, 6 %). The major cellular fatty acids of strain SJ5-4T were anteiso-C15 : 0, iso-C15 : 0, anteiso-C17 : 0, iso-C16 : 0 and C16 : 0. Phosphatidylglycerol, diphosphatidylglycerol, phosphatidylinositol, an unidentified phospholipid, three glycolipids and an unidentified lipid were detected as the polar lipids. Strain SJ5-4T belonged to the exceptionally small group of strains within the order Micrococcales that show a peptidoglycan cross-linked according to the A-type but containing 2,4-diaminobutyric acid. The G+C content of the genomic DNA was 61.8 mol%. MK-7, MK-8 and MK-9 were detected as the isoprenoid quinones. Strain SJ5-4T was most closely related to members of the genus Nesterenkonia, with 16S rRNA gene sequence similarities of 93.1–94.8 %. However, phylogenetic inference based on 16S rRNA gene sequences showed that strain SJ5-4T formed a phyletic lineage distinct from members of the genus Nesterenkonia within the family Micrococcaceae . On the basis of its phenotypic and molecular features, strain SJ5-4T represents a novel genus and species of the family Micrococcaceae , for which the name Garicola koreensis gen. nov., sp. nov. is proposed. The type strain of Garicola koreensis is SJ5-4T ( = KACC 16909T = JCM 18572T = DSM 28238T).

A Gram-staining-negative, non-motile, catalase- and oxidase-positive strain, designated CCNWSP36-1T, was isolated from the nodule surface of soybean [Glycine max (L.) Merrill] cultivar Zhonghuang 13. The 16S rRNA gene sequence analysis clearly showed that the isolate represented a member of the genus Sphingobacterium . On the basis of pairwise comparisons of 16S rRNA gene sequences, strain CCNWSP36-1T showed 96.8 % similarity to Sphingobacterium nematocida CCTCC AB 2010390T and less than 95.2 % similarity to other members of the genus Sphingobacterium . Growth of strain CCNWSP36-1T occurred at 10–40 °C and at pH 5.0–9.0. The NaCl range (w/v) for growth was 0–4 %. The predominant isoprenoid quinone was MK-7. The polar lipids were phosphatidylethanolamine and several unidentified polar lipids. Sphingolipid was present. The major fatty acids were iso-C15 : 0 and summed feature 3 (comprising C16 : 1ω6c and/or C16 : 1ω7c). The G+C content of the genomic DNA was 41.1 mol%. As the physiological and biochemical characteristics of strain CCNWSP36-1T and the type strains of its closest phylogenetic neighbours showed clear differences, a novel species, Sphingobacterium yanglingense, is proposed. The type strain is CCNWSP36-1T ( = ACCC 19328T = JCM 30166T).

Two Gram-stain-negative and non-flagellated bacteria, YSTF-M3T and YSTF-M6T, were isolated from a tidal flat from Yellow Sea, Republic of Korea, and subjected to a polyphasic taxonomic study. Neighbour-joining phylogenetic tree of 16S rRNA gene sequences showed that strains YSTF-M3T and YSTF-M6T belong to the genera Kordia and Olleya of the family Flavobacteriaceae , respectively. The 16S rRNA gene sequence similarities between strain YSTF-M3T and the type strains of Kordia species and between strain YSTF-M6T and the type strains of Olleya species were 94.1–98.4 and 97.3–98.3 %, respectively. The ANI and dDDH values between genomic sequences of strain YSTF-M3T and the type strains of five Kordia species and between those of strain YSTF-M6T and the type strains of three Olleya species were in ranges of 77.0–83.2 and 20.7–27.1 % and 79.4–81.5 and 22.3–23.9 %, respectively. The DNA G+C contents of strain YSTF-M3T and YSTF-M6T from genomic sequences were 34.1 and 31.1 %, respectively. Both strains contained MK-6 as predominant menaquinone and phosphatidylethanolamine as only major phospholipid identified. Differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, revealed that strains YSTF-M3T and YSTF-M6T are separated from recognized species of the genera Kordia and Olleya , respectively. On the basis of the data presented, strains YSTF-M3T (=KACC 21639T=NBRC 114499T) and YSTF-M6T (=KACC 21640T=NBRC 114500T) are considered to represent novel species of the genera Kordia and Olleya , respectively, for which the names Kordia aestuariivivens sp. nov. and Olleya sediminilitoris sp. nov. are proposed.

A novel Gram-stain-negative, rod-shaped, yellow bacterium, designated as LB1R16T, was isolated from the Laigu glacier on the Tibetan Plateau, PR China. Strain LB1R16T was catalase-positive, oxidase-negative and grew at 0–28 °C, pH 6.0–8.0 and in the absence of NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain LB1R16T belongs to the family Sphingosinicellaceae but formed an independent lineage. The highest level of 16S rRNA gene sequence similarities were found to Polymorphobacter arshaanensis DJ1R-1T (95.24 %), Sphingoaurantiacus capsulatus YLT33T (94.78 %) and Sandarakinorhabdus limnophila DSM 17366T (94.67 %). The genomic DNA G+C content was 68.8 mol%. The main cellular fatty acids were summed feature 8 (C18 : 1  ω7c/C18 : 1  ω6c), summed feature 3 (C16 : 1  ω7c/C16 : 1  ω6c), C16 : 0 and C12 : 0-OH. The respiratory quinone was ubiquinone-10. The polar lipids were phosphatidylethanolamine, phosphatidylglycerol, one sphingoglycolipid, one unidentified aminolipid, one unidentified phospholipid and two unidentified polar lipids, which were different from the type strains of Polymorphobacter arshaanensis , Sphingoaurantiacus capsulatus and Sandarakinorhabdus limnophila . Based on a polyphasic approach, a novel species of a new genus, Glacieibacterium frigidum gen. nov., sp. nov., within the family Sphingosinicellaceae is proposed. The type strain is LB1R16T (=CGMCC 1.11941T=NBRC 113873T).
