The actinomycetes strains KRD168T and KRD185T were isolated from sediments collected from the deep Southern Ocean and, in this work, they are described as representing two novel species of the genus Pseudonocardia through a polyphasic approach. Despite sharing >99 % 16S rRNA gene sequence similarity with other members of the genus, comparative genomic analysis allowed species delimitation based on average nucleotide identity and digital DNA–DNA hybridization. The KRD168T genome is characterized by a size of 6.31 Mbp and a G+C content of 73.44 mol%, while the KRD185T genome has a size of 6.82 Mbp and a G+C content of 73.98 mol%. Both strains contain meso-diaminopimelic acid as the diagnostic diamino acid, glucose as the major whole-cell sugar, MK-8(H4) as a major menaquinone and iso-branched hexadecanoic acid as a major fatty acid. Biochemical and fatty acid analyses also revealed differences between these strains and their phylogenetic neighbours, supporting their status as distinct species. The names Pseudonocardia abyssalis sp. nov. (type strain KRD168T=DSM 111918T=NCIMB 15270T) and Pseudonocardia oceani (type strain KRD185T=DSM 111919T=NCIMB 15269T) are proposed.

An orange-pigmented, Gram-staining-negative, rod-shaped bacterium, designated 96_Hippo_TS_3/13T was isolated from the brood pouch of a diseased seahorse male of the species Hippocampus barbouri from the animal facility of the University of Giessen, Germany. Phylogenetic analyses based on the nearly full-length 16S rRNA gene sequence placed strain 96_Hippo_TS_3/13T into the monophyletic cluster of the genus Mesonia within the family Flavobacteriaceae. However, the strain shared only 92.2–93.8 % sequence similarity to type strains of species of the genus Mesonia, with highest sequence similarity to the type strain of Mesonia aquimarina. Cellular fatty acid analysis showed a Mesonia-typical fatty acid profile including several branched and hydroxyl fatty acids with highest amounts of iso-C15 : 0 (40.9 %) followed by iso-C17 : 0 3-OH (14.8 %). In the polyamine pattern, sym-homospermidine was predominant. The diagnostic diamino acid of the peptidoglycan was meso-diaminopimelic acid. The quinone system contained exclusively menaquinone MK-6. The only identified compound in the polar lipid profile was phosphatidylethanolamine present in major amounts. Additionally, major amounts of an unidentified aminolipid and two unidentified lipids not containing a phosphate group, an amino group or a sugar residue were detected. The genomic G+C content of strain 96_Hippo_TS_3/13T was 30 mol%. Based on genotypic, chemotaxonomic and physiological characterizations we propose a novel species of the genus Mesonia, Mesonia hippocampi sp. nov., with strain 96_Hippo_TS_3/13T ( = CIP 110839T =  LMG 28572T = CCM 8557T) as the type strain. An emended description of the genus Mesonia is also provided.

Phosphatidylinositol Mannosides

Strain HNM0947T, representing a novel actinobacterium, was isolated from the coral Galaxea astreata collected from the coast of Wenchang, Hainan, China. The strain was found to have morphological and chemotaxonomic characteristics consistent with the genus Nocardiopsis . The organism formed abundant fragmented substrate mycelia and aerial mycelia which differentiated into non-motile, rod-shaped spores. Whole-cell hydrolysates contained meso-diaminopimelic acid and no diagnostic sugars. The major menaquinones were MK-10(H8), MK-10(H6) and MK-10(H4). The major phospholipids were phosphatidylcholine, phosphatidylglycerol, phosphatidylinositol and phosphatidylinositol mannosides. The major fatty acids were iso-C16:0, anteiso-C17:0, C18:0, C18:0 10-methyl (TBSA) and anteiso-C15:0. The G+C content was 71.3 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain HNM0947T belonged to the genus Nocardiopsis and shared highest sequence similarity to Nocardiopsis salina YIM 90010T (98.8%), Nocardiopsis xinjiangensis YIM 90004T(98.5%) and Nocardiopsis kunsanensis DSM 44524T (98.3%). The strain HNM0947T was distinguished from its closest type strain by low average nucleotide identity (90.8%) and dDDH values (60.4%) respectively. Based on genotypic, chemotaxonomic and phenotypic characteristics, it was concluded that strain HNM0947T represents a novel species of the genus Nocardiopsis whose name was proposed as Nocardiopsis coralli sp. nov. The type strain was HNM0947T (=CCTCC AA 2020015 T=KCTC 49525 T).

A novel filamentous bacterium, designated Nari11AT, was isolated from soil collected from a salt lake named Chott Melghir, located in north-eastern Algeria. The strain is an aerobic, halophilic, thermotolerant, Gram-stain-positive bacterium, growing at NaCl concentrations between 5 and 20 % (w/v) and at 43–60 °C and pH 5.0–10.0. The major fatty acids were iso-C15 : 0, anteiso-C15 : 0 and iso-C17 : 0. The DNA G+C content was 53.4 mol%. ll-Diaminopimelic acid was the diamino acid of the peptidoglycan. The major menaquinone was MK-7, but MK-6 and MK-8 were also present in trace amounts. The polar lipid profile consisted of phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylmonomethylethanolamine and three unidentified phospholipids. Results of molecular and phenotypic analyses led to the description of the strain as a novel member to the genus Melghirimyces , family Thermoactinomycetaceae . Strain Nari11AT shows 96.7 % 16S rRNA gene sequence similarity to the type strain of Melghirimyces algeriensis . On the basis of phenotypic, physiological and phylogenetic data, strain Nari11AT ( = DSM 45514T  = CCUG 60050T) represents the type strain of a novel species, for which the name Melghirimyces thermohalophilus sp. nov. is proposed.

Spore Forming Bacteria

Two Gram-positive, rod-shaped, non-spore-forming bacteria (strains RHLT1-17T and RHLT2-1T) were isolated from Hailuogou glacier in Szechwan province, PR China. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the strains belonged to the genus Nocardioides and shared 97.8 % sequence similarity with each other and 97.6 and 98.4 % sequence similarity, respectively, with Nocardioides kribbensis KSL-2T. Strain RHLT1-17T grew at 0–35 °C and strain RHLT2-1T grew at 0–25 °C. The major cellular fatty acids of strain RHLT1-17T were C17 : 1ω8c (32.69 %) and iso-C16 : 0 (21.74 %). The major cellular fatty acids of strain RHLT2-1T were C18 : 1ω9c (28.72 %), summed feature 3 (17.14 %; comprising C16 : 1ω7c and/or C16 : 1ω6c), iso-C16 : 0 (14.35 %), C16 : 0 (9.96 %) and iso-C14 : 0 (8.34 %). Both strains contained ll-2,6-diaminopimelic acid in the cell-wall peptidoglycan and MK-8(H4) as the predominant menaquinone. On the basis of data obtained using a polyphasic approach, two novel species, Nocardioides szechwanensis sp. nov. (type strain RHLT1-17T  = CGMCC 1.11147T  = NBRC 108562T) and Nocardioides psychrotolerans sp. nov. (type strain RHLT2-1T  = CGMCC 1.11156T  = NBRC 108563T), are proposed.

Novel Bacteria

Two novel bacteria, designated strains Gsoil 634T and Dae 20T, were isolated in South Korea from soil of a ginseng field and freshwater sediment, respectively and were characterized by a polyphasic approach to clarify their taxonomic positions. Phylogenetic analysis based on 16S rRNA gene sequences indicated that, although they probably represented two distinct species (indicated by a sequence similarity of 96.6 %), both strain Gsoil 634T and strain Dae 20T belonged to the genus Sphingomonas and were most closely related to ‘Sphingomonas humi’ PB323 (97.8 % and 96.7 % sequence similarity, respectively), Sphingomonas kaistensis PB56T (96.8 % and 96.7 %), Sphingomonas astaxanthinifaciens TDMA-17T (96.6 % and 95.4 %) and Sphingomonas jaspsi TDMA-16T (95.6 % and 95.8 %). For both novel strains, the major ubiquinone was Q-10, the major polyamine was homospermidine, the major cellular fatty acids included summed feature 7 (C18 : 1ω7c, C18 : 1ω9t and/or C18 : 1ω12t), C17 : 1ω6c and C16 : 0, and the polar lipids included sphingoglycolipid. These chemotaxonomic data supported the affiliation of both strains to the genus Sphingomonas . However, the DNA–DNA relatedness value between strain Gsoil 634T and ‘Sphingomonas humi’ PB323T was 31 %. Moreover, the results of physiological and biochemical tests allowed the phenotypic differentiation of strains Gsoil 634T and Dae 20T from established members of the genus Sphingomonas . Based on these data, the two isolates represent two novel species in the genus Sphingomonas , for which the names Sphingomonas ginsengisoli sp. nov. (type strain Gsoil 634T = KCTC 12630T = DSM 18094T = LMG 23739T) and Sphingomonas sediminicola sp. nov. (type strain Dae 20T  = KCTC 12629T = DSM 18106T = LMG 23592T) are proposed.

Two strains, 8-4-E12T and 8-4-E13T, were isolated from a biowaste composting reactor. Based on 16S rRNA gene sequences, both strains belong to the genus Bacillus . Strain 8-4-E12T was most closely related to the type strains of Bacillus shackletonii , B. acidicola , B. sporothermodurans and B. oleronius (96.4, 96.3, 96.0 and 95.6 % 16S rRNA gene similarity, respectively), whereas strain 8-4-E13T was most closely related to the type strain of Bacillus humi (96.5 % sequence similarity). Strains 8-4-E12T and 8-4-E13T shared 94 % 16S rRNA gene sequence similarity. The fatty acid profile of strain 8-4-E12T was dominated by saturated iso- and anteiso-branched fatty acids (iso-C15 : 0, anteiso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0), and also contained considerable amounts of C16 : 0. The fatty acid profile of strain 8-4-E13T showed a predominance of iso-C15 : 0 (65 %), with smaller amounts of other saturated branched-chain fatty acids along with an unsaturated alcohol. Both strains contained diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine as major polar lipids. Additionally, strain 8-4-E12T contained an unknown lipid and strain 8-4-E13T two unknown (amino-)phospholipids. The diagnostic diamino acid found in the cell-wall peptidoglycan of 8-4-E12T and 8-4-E13T was meso-diaminopimelic acid. The predominant menaquinone was MK-7. The results of physiological and biochemical tests also allowed phenotypic differentiation of the two strains from each other and from related Bacillus species. On the basis of their phylogenetic, phenotypic and chemotaxonomic properties, strains 8-4-E12T and 8-4-E13T represent novel species of the genus Bacillus , for which the names Bacillus pervagus sp. nov. (type strain 8-4-E12T = DSM 23947T = LMG 27601T) and Bacillus andreesenii sp. nov. (type strain 8-4-E13T = DSM 23948T = LMG 27602T) are proposed.

Two novel endospore-forming, aerobic bacilli, strains E173aT and E265T, were isolated from soil and sediment samples from Kozakli and Altinsu hot springs, Nevsehir (Turkey). Their young cells in the exponential phase of growth were motile, Gram-stain-positive, straight rods, 0.6–1.1×3.0–8.0 µm in size, but they became strikingly long, approximately 0.6–1.2 by 9.0–35.0 µm, after the stationary phase of growth. Cells varied in tests for oxidase, and had a weakly positive reaction for catalase. Both strains could grow between 40 and 70 °C, with optimal growth at 60 °C (E173aT) and 55 °C (E265T). Growth occurred within the range pH 5.0–11.0 with optimal growth at pH 9.0 (E173aT) and pH 8.5 (E265T). Strain E173aT grew within a salinity range from 0 to1.5 % (w/v) NaCl with optimal growth at 0.5 %, while strain E265T grew within the range 0–5.0 % (w/v), with an optimum at 3.0 %. The new isolates differed from each other in some phenotypic and chemotaxonomic characters as well as repetitive extragenic palindromic element PCR (rep-PCR) fingerprints. 16S rRNA gene sequence similarities suggested distant relationships with other members of the family Bacillaceae (<95.8 %), although the two strains showed 97.5 % sequence similarity between them, and had 55 % relatedness by DNA–DNA hybridization. The DNA G+C contents were 44.8 (E173aT) and 43.5 mol% (E265T). Moreover, the chemotaxonomic data of E173aT and E265T [presence of low amounts of meso-diaminopimelic acid, A1γ to A1γ′ cross-linkage types in peptidoglycan, fatty acids including iso-C15 : 0 (>60 %), iso-C17 : 0 and C16 : 0] supported the consideration of these isolates as members of a novel genus. Based upon phenotypic, phylogenetic and chemotaxonomic characteristics, it is proposed that new isolates represent a novel genus, Thermolongibacillus gen. nov., with two novel species: Thermolongibacillus altinsuensis sp. nov. (type strain E265T = DSM 24979T = NCIMB 14850T) and Thermolongibacillus kozakliensis sp. nov. (type strain E173aT = DSM 24978T = NCIMB 14849T).

A Gram-stain-negative, non-motile, non-spore-forming, aerobic, rod-shaped bacterial strain, designated DPG-28T, was isolated from seawater on the southern coast of Korea. Strain DPG-28T grew optimally at 30 °C and in the presence of 2 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain DPG-28T formed a coherent cluster with members of the genera Marivita and Gaetbulicola , with which it exhibited sequence similarity values of 97.8–98.5 %. The DNA G+C content of strain DPG-28T was 65.1 mol%. The predominant ubiquinone of strain DPG-28T was ubiquinone-10 (Q-10), consistent with data for the genera Marivita and Gaetbulicola . The cellular fatty acid profiles of strain DPG-28T and the type strains of Marivita cryptomonadis , Marivita litorea and Gaetbulicola byunsanensis were essentially similar in that the common predominant fatty acid was C18 : 1ω7c. Major polar lipids found in strain DPG-28T and the type strains of M. cryptomonadis , M. litorea and G. byunsanensis were phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine and an unidentified aminolipid. From these data, it is proposed that Gaetbulicola byunsanensis be reclassified as a member of the genus Marivita , for which the name Marivita byunsanensis comb. nov. is proposed, with the type strain SMK-114T ( = CCUG 57612T  = KCTC 22632T), and that strain DPG-28T be classified in the genus Marivita . Differential phenotypic properties and genetic distinctiveness of strain DPG-28T demonstrated that this strain is distinguishable from M. cryptomonadis , M. litorea and G. byunsanensis . On the basis of the data presented, strain DPG-28T is considered to represent a novel species of the genus Marivita , for which the name Marivita hallyeonensis sp. nov. is proposed. The type strain is DPG-28T ( = KCTC 23421T  = CCUG 60522T). An emended description of the genus Marivita is also provided.

A Gram-stain-negative, non-motile, aerobic and coccoid, ovoid or rod-shaped bacterial strain, designated BS-W9T, was isolated from a tidal flat of the South Sea, South Korea. Strain BS-W9T grew optimally at 25–30 °C, at pH 7.0–8.0 and in the presence of approximately 2.0 % (w/v) NaCl. Phylogenetic trees, based on 16S rRNA gene sequences, revealed that strain BS-W9T clustered with the type strain of Halocynthiibacter namhaensis , showing a highest sequence similarity of 97.3 %. It exhibited sequence similarity values of less than 95.6 % to the type strains of other species with validly published names. Strain BS-W9T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c as the predominant fatty acid. The major polar lipids of strain BS-W9T were phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, one unidentified lipid and one unidentified aminolipid. The fatty acid and polar lipid profiles of strain BS-W9T were distinguished from those of the type strains of H. namhaensis and other phylogenetically related genera. The DNA G+C content of strain BS-W9T was 53.2 mol% and its mean DNA–DNA relatedness value with H. namhaensis RA2-3T was 14 %. On the basis of the phylogenetic, chemotaxonomic and other phenotypic properties, strain BS-W9T is considered to represent a novel genus and species within the family Rhodobacteraceae , for which the name Pseudohalocyntiibacter aestuariivivens gen. nov., sp. nov. is proposed. The type strain of Pseudohalocyntiibacter aestuariivivens is BS-W9T ( = KCTC 42348T = CECT 8726T).
