A Gram-negative, rod-shaped, oxidase-positive, non-spore-forming, non-motile bacterium (Sa25T) was isolated from air of a duck barn. 16S rRNA gene and recA sequence analyses clearly placed the isolate in the vicinity of the Brucella–Ochrobactrum–Pseudochrobactrum group, with the closest relative being Pseudochrobactrum glaciei KMM 3858T. This allocation was confirmed by analyses of the quinone system (ubiquinone Q-10), fatty acid data (major fatty acids C18 : 1 ω7c and C19 : 0 cyclo ω8c) and polar lipid profile (major components diphosphatidylglycerol, phosphatidylmonomethylethanolamine, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine and unknown aminolipid AL1; moderate amounts of three unknown polar lipids, L1–L3, an unknown aminolipid and an unknown aminophospholipid APL2). The polyamine pattern of Sa25T exhibited the major compound putrescine and moderate amounts of spermidine; a similar polyamine pattern with the major compound putrescine was also detected in Pseudochrobactrum glaciei KMM 3858T. DNA–DNA hybridization of strain Sa25T with Pseudochrobactrum glaciei KMM 3858T and the type strains of the other Pseudochrobactrum species showed values ranging from 50.3 to 24.8 %, and physiological and biochemical data clearly differentiated this isolate from the described Pseudochrobactrum species. Since Sa25T and Pseudochrobactrum glaciei KMM 3858T form a distinct lineage in the 16S rRNA gene sequence-based phylogenetic tree, and this separate position is supported by unique characteristics of their polyamine patterns and polar lipid profiles, we propose the novel genus Paenochrobactrum gen. nov., with the type species Paenochrobactrum gallinarii sp. nov. (type strain Sa25T =CCUG 57736T =CCM 7656T) and the reclassification of Pseudochrobactrum glaciei as Paenochrobactrum glaciei comb. nov. (type strain Pi26T =KMM 3858T =NRIC 0733T =JCM 15115T).

Biochemical and molecular genetic studies were performed on three novel Gram-stain-negative, catalase- and oxidase-positive, bacilli-shaped organisms isolated from the tonsils of two pigs and one wild boar. The micro-organism was identified as a species of the genus Pelistega based on its cellular morphological and biochemical tests. The closest phylogenetic relative of the novel bacilli was Pelistega indica HM-7T (98.2 % 16S rRNA gene sequence similarity to the type strain). groEL and gyrB sequence analysis showed interspecies divergence from the closest 16S rRNA gene phylogenetic relative, P. indica of 87.0.% and 69 %, respectively. The polyamine pattern contains predominantly putrescine and 2-hydroxyputrescine. The major quinone is ubiquinone Q-8 and in the polar lipid profile, phosphatidylethanolamine, phosphatidylglycerol, an unidentified aminolipid and an unidentified lipid are predominant. The novel bacterial isolate can be distinguished from P. indica by several biochemical characteristics, such as the production of l-pyrrolydonil arylamidase but not gamma-glutamyl-transferase, and the utilization of different carbon sources. Based on both phenotypic and phylogenetic findings, the novel bacterium is classified as representing a novel species of the genus Pelistega, for which the name Pelistega suis sp. nov. is proposed. The type strain is 3340-03T ( = CECT 8400T = CCUG 64465T).

A Gram-stain-negative, aerobic, non-motile and rod-shaped bacterial strain, designated W-WS13T, was isolated from wood falls collected around Wando, an island in the South Sea of South Korea, and subjected to a polyphasic taxonomic study. Strain W-WS13T grew optimally at 30 °C, at pH 7.5 and in the presence of 0.5 % NaCl. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showed that strain W-WS13T belonged to the genus Pedobacter, clustering robustly with the type strain of Pedobacter arcticus, sharing 95.9 % sequence similarity. Strain W-WS13T exhibited 16S rRNA gene sequence similarity of 90.1–95.6 % to the type strains of the other species of the genus Pedobacter. Strain W-WS13T contained MK-7 as the predominant menaquinone and iso-C15 : 0, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and iso-C17 : 0 3-OH as the major fatty acids. The major polar lipid detected in strain W-WS13T was phosphatidylethanolamine. The DNA G+C content of strain W-WS13T was 36.9 mol%. Phylogenetic distinctiveness and differential phenotypic properties of strain W-WS13T revealed that the novel strain is separated from recognized species of the genus Pedobacter. On the basis of the data presented, strain W-WS13T is considered to represent a novel species of the genus Pedobacter, for which the name Pedobacter lignilitoris sp. nov. is proposed. The type strain is W-WS13T ( = KCTC 42500T = CECT 8725T).

A Gram-stain-negative, aerobic, rod-shaped, non-flagellated marine bacterium, designated strain LS-861T, was isolated from seawater of the South China Sea (Taiwan). Strain LS-861T grew optimally at pH 7.0 and 30 °C in the presence of 3 % (w/v) NaCl. The novel strain shared highest 16S rRNA gene sequence similarity (91.5 % each) with ‘Nitratireductor shengliensis’ CGMCC 1.12519 and Hoeflea halophila JG120-1T and lower sequence similarity ( < 91.5 %) with other species. Phylogenetic analyses based on 16S rRNA gene sequences revealed a distinct taxonomic position attained by strain LS-861T within the clade that accommodated members of the family Phyllobacteriaceae. The major fatty acids were C16 : 0, iso-C17 : 1ω10c, C18 : 0 3-OH and C18 : 1ω7c/C18 : 1ω6c. The polar lipid profile was relatively simple as compared with other representatives of Phyllobacteriaceae, by having major amounts of diphosphatidylglycerol, phosphatidylglycerol and an unidentified glycolipid, and moderate amounts of three unidentified phospholipids and an unidentified aminolipid. The DNA G+C content was 61.2 mol%. The predominant quinone system was ubiquinone-10 (Q-10). The data in general and phylogenetic and polar lipid data in particular clearly distinguish the novel strain from related species at the genus level. Thus, strain LS-861T is suggested to represent a novel species of a new genus of the family Phyllobacteriaceae, for which the name Thalassocola ureilytica gen. nov., sp. nov. is proposed. The type strain of Thalassocola ureilytica is LS-861T ( = BCRC 80818T = JCM 30682T).

A novel Gram-stain-positive actinobacterium, designated strain SCSIO 11529T, was isolated from tissues of the stony coral Galaxea fascicularis, and characterized by using a polyphasic approach. The temperature range for growth was 22–50 °C (optimum 28–45 °C), the pH range for growth was 6.0–8.0 (optimum pH 7.0), and the NaCl concentration range for growth was 0–7 % (w/v) NaCl. The polar lipid profile contained diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol, phosphatidylmethylethanolamine, phosphatidylethanolamine and an unknown polar lipid. The predominant menaquinone was MK-9(H4). The major fatty acids (>10 %) were iso-C16 : 0, iso-C17 : 1ω6c, iso-C16 : 1 H and C16 : 1ω7c/iso-C15 : 0 2-OH. The DNA G+C content of strain SCSIO 11529T was 70.2 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain SCSIO 11529T belongs to the genus Prauserella , with the closest neighbours being Prauserella marina MS498T (97.0 % 16S rRNA gene sequence similarity), Prauserella rugosa DSM 43194T (96.4 %) and Prauserella flava YIM 90630T (95.9 %). Based on the evidence of the present study, strain SCSIO 11529T is considered to represent a novel species of the genus Prauserella , for which the name Prauserella coralliicola sp. nov. is proposed. The type strain is SCSIO 11529T ( = DSM 45821T = NBRC 109418T).

Mycobacterium Simiae

Four strains isolated in the last 15 years were revealed to be identical in their 16S rRNA gene sequences to MCRO19, the sequence of which was deposited in GenBank in 1995. In a polyphasic analysis including phenotypic and genotypic features, the five strains (including MCRO19), which had been isolated in four European countries, turned out to represent a unique taxonomic entity. They are scotochromogenic slow growers and are genetically related to the group that included Mycobacterium simiae and 15 other species. The novel species Mycobacterium europaeum sp. nov. is proposed to accommodate these five strains. Strain FI-95228T ( = DSM 45397T  = CCUG 58464T) was chosen as the type strain. In addition, a thorough revision of the phenotypic and genotypic characters of the species related to M. simiae was conducted which leads us to suggest the denomination of the ‘Mycobacterium simiae complex’ for this group.

A Gram-stain-negative, aerobic, non-spore-forming, motile by single polar flagellum and ovoid or rod-shaped bacterial strain, designated JBTF-M23T, was isolated from tidal flat sediment collected from the Yellow Sea, Republic of Korea. Neighbour-joining phylogenetic tree of 16S rRNA gene sequences showed that strain JBTF-M23T fell within the clade comprising the type strains of Pseudoalteromonas species, clustering with the type strains of P. byunsanensis and P. amylolytica . Strain JBTF-M23T exhibited the highest 16S rRNA gene sequence similarity value (98.6 %) to the type strain of P. rubra and sequence similarities of 98.3 and 97.7 % to the type strains of P. byunsanensis and P. amylolytica, respectively. The DNA G+C content of strain JBTF-M23T from genomic sequence data was 41.98 %. The ANI and dDDH values between strain JBTF-M23T and the type strains of P. rubra , P. byunsanensis and P. amylolytica were 71.3–76.6 and 19.4–19.9 %, respectively. Strain JBTF-M23T contained Q-8 as the predominant ubiquinone and C16 : 1  ω7c and/or C16 : 1  ω6c, C16 : 0 and C18 : 1  ω7c as the major fatty acids. The major polar lipids of strain JBTF-M23T were phosphatidylethanolamine and one unidentified aminolipid. Distinguished phenotypic properties, along with the phylogenetic and genetic distinctiveness, revealed that strain JBTF-M23T is separated from recognized Pseudoalteromonas species. On the basis of the data presented, strain JBTF-M23Tis considered to represent a novel species of the genus Pseudoalteromonas , for which the name Pseudoalteromonas caenipelagi sp. nov. is proposed. The type strain is JBTF-M23T(=KACC 19900T=NBRC 113647T).

Members of the metabolically diverse order Nitrosomonadales inhabit a wide range of environments. Two strains affiliated with this order were isolated from soils in Germany and characterized by a polyphasic approach. Cells of strains 0125_3T and Swamp67T are Gram-negative rods, non-motile, non-spore-forming, non-capsulated and divide by binary fission. They tested catalase-negative, but positive for cytochrome c-oxidase. Both strains form small white colonies on agar plates and grow aerobically and chemoorganotrophically on SSE/HD 1 : 10 medium, preferably utilizing organic acids and proteinaceous substrates. Strains 0125_3T and Swamp67T are mesophilic and grow optimally without NaCl addition at slightly alkaline conditions. Major fatty acids are C16 : 1  ω7c, C16 : 0 and C14 : 0. The major polar lipids are diphosphatidylglycerol, phosphatidylethanolamine and phosphatidyglycerol. The predominant respiratory quinone is Q-8. The G+C content for 0125_3T and Swamp67T was 67 and 66.1 %, respectively. The 16S rRNA gene analysis indicated that the closest relatives (<91 % sequence similarity) of strain 0125_3T were Nitrosospira multiformis ATCC 25196T, Methyloversatilis universalis FAM5T and Denitratisoma oestradiolicum AcBE2-1T, while Nitrosospira multiformis ATCC 25196T, Nitrosospira tenuis Nv1T and Nitrosospira lacus APG3T were closest to strain Swamp67T. The two novel strains shared 97.4 % 16S rRNA gene sequence similarity with one another and show low average nucleotide identity of their genomes (83.8 %). Based on the phenotypic, chemotaxonomic, genomic and phylogenetic analysis, we propose the two novel species Usitatibacter rugosus sp. nov (type strain 0125_3T=DSM 104443T=LMG 29998T=CECT 9241T) and Usitatibacter palustris sp. nov. (type strain Swamp67T=DSM 104440T=LMG 29997T=CECT 9242T) of the novel genus Usitatibacter gen. nov., within the novel family Usitatibacteraceae fam. nov.

A Gram-negative, motile, rod-shaped, Marinobacter-like bacterial strain, ISL-40T, was isolated from a marine solar saltern of the Yellow Sea in Korea. The taxonomic position of the novel strain was investigated using a polyphasic approach. Strain ISL-40T grew optimally at pH 7.0–8.0 and at 30 °C. It contained Q-9 as the predominant ubiquinone. The major fatty acids were C16 : 0, C16 : 1 ω7c and/or iso-C15 : 0 2-OH and 10-methyl C16 : 0. The DNA G+C content was 58.1 mol%. A phylogenetic analysis based on 16S rRNA gene sequences showed that strain ISL-40T belongs to the genus Marinobacter. Strain ISL-40T exhibited 16S rRNA gene sequence similarity values of 93.5–96.4 % to the type strains of recognized Marinobacter species. The differential phenotypic properties and phylogenetic distinctiveness of strain ISL-40T revealed that it is separate from recognized Marinobacter species. On the basis of phenotypic, phylogenetic and genetic data, therefore, strain ISL-40T represents a novel species of the genus Marinobacter, for which the name Marinobacter salicampi sp. nov. is proposed. The type strain is ISL-40T (=KCTC 12972T=CCUG 54357T).

ABSTRACT A Gram-stain-negative bacterial strain, JBTF-M27T, was isolated from a tidal flat from Yellow Sea, Republic of Korea. Neighbor-joining phylogenetic tree of 16S rRNA gene sequences showed that strain JBTF-M27T fell within the clade comprising the type strains of Sulfitobacter species. Strain JBTF-M27T exhibited the highest 16S rRNA gene sequence similarity (98.8%) to the type strain of S. porphyrae. Genomic ANI and dDDH values of strain JBTF-M27T between the type strains of Sulfitobacter species were less than 76.1 and 19.2%, respectively. Mean DNA-DNA relatedness value between strain JBTF-M27T and the type strain of S. porphyrae was 21%. DNA G + C content of strain JBTF-M27T from genome sequence was 57.8% (genomic analysis). Strain JBTF-M27T contained Q-10 as the predominant ubiquinone and C18:1ω7c as the major fatty acid. The major polar lipids of strain JBTF-M27T were phosphatidylcholine, phosphatidylglycerol and one unidentified aminolipid. Distinguished phenotypic properties, along with the phylogenetic and genetic distinctiveness, revealed that strain JBTF-M27T is separated from recognized Sulfitobacter species. On the basis of the data presented, strain JBTF-M27T ( = KACC 21648T = NBRC 114356T) is considered to represent a novel species of the genus Sulfitobacter, for which the name Sulfitobacter sediminilitoris sp. nov. is proposed.

A novel actinomycete, strain KST3-10T, was isolated from sand sediment of a beach in Jeju, Korea, and was subjected to polyphasic taxonomic characterization. The organism produced circular, smooth, translucent, apricot-coloured colonies comprising coccoid- or rod-shaped cells. Phylogenetic analyses based on 16S rRNA gene sequences showed that the organism belonged to the family Geodermatophilaceae and consistently formed a distinct sub-branch outside the radiation of the genus Blastococcus. The organism showed 16S rRNA gene sequence similarity values of 98.2 % with respect to Blastococcus aggregatus DSM 4725T and 98.1 % with respect to Blastococcus saxobsidens BC444T. The type strains of the two Blastococcus species shared 98.2 % sequence similarity with respect to each other, whereas the levels of sequence similarity between the novel organism and the type strains of the less closely related neighbours, Modestobacter multiseptatus and Geodermatophilus obscurus, were in the range 96.2–96.9 %. The physiological, biochemical and chemotaxonomic data revealed that the novel organism can be readily differentiated from members of the genus Blastococcus and that it merits separate species status. On the basis of the phenotypic and genotypic evidence, strain KST3-10T represents a novel species of the genus Blastococcus, for which the name Blastococcus jejuensis sp. nov. is proposed. The type strain is KST3-10T (=NRRL B-24440T=KCCM 42251T).
