A beige-pigmented bacterium (strain CCUG 53761AT) was isolated from human blood from an 85-year-old man in Göteborg, Sweden. Comparative analysis of 16S rRNA gene sequences showed that this bacterium displayed <95 % similarity to all described species of the genera of the family Alcaligenaceae. It grouped within the radiation of the genus Alcaligenes, but showed only 93.0–94.8 % similarity to type strains of members of this genus (Alcaligenes faecalis subsp. parafaecalis, 94.8 %; Alcaligenes faecalis subsp. faecalis, 94.2 %; Alcaligenes faecalis subsp. phenolicus, 93.4 %). This discrimination was supported by chemotaxonomic differences. The polyamine pattern consisted of the predominant compound putrescine, moderate amounts of spermidine and minor to trace amounts of spermine and cadaverine; 2-hydroxyputrescine was not detectable. The quinone system was ubiquinone Q-8 with minor amounts of Q-7. The polar lipid profile was composed of the major lipids diphosphatidylglycerol and phosphatidylethanolamine and moderate amounts of phosphatidylglycerol and an unknown phospholipid; minor lipids were also detected. The fatty acid profile, with large amounts of C16 : 0 and C17 : 0 cyclo and the absence of C12 : 0 2-OH as hydroxylated fatty acid, also differed significantly from those reported for Alcaligenes species. On the basis of these data, it is proposed that strain CCUG 53761AT represents a novel genus and species, for which the name Paenalcaligenes hominis gen. nov., sp. nov. is proposed. The type strain of Paenalcaligenes hominis is CCUG 53761AT =CCM 7698T.

A Gram-stain-negative, non-motile, mesophilic, aerobic, rod-shaped or spherical bacterium, strain 2A-7T, was isolated from surface seawater at Muroto city, Kochi prefecture, Japan. The strain produced a pigment(s), the absorption spectrum of which closely resembled that of β-carotene. Phylogenetic analyses based on 16S rRNA gene sequences showed that the strain fell within the family Flavobacteriaceae and clustered distantly with the type strains of species of the genus Lutibacter (up to 93.9 % similarity). The DNA G+C content was 34.1 mol%. The major fatty acids were summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1ω7c), iso-C17 : 0 3-OH and iso-C15 : 0 3-OH. The major polar lipids were phosphatidylethanolamine and three unidentified lipids. Menaquinone 6 was detected as the sole isoprenoid quinone. On the basis of phenotypic, genotypic and chemotaxonomic data, strain 2A-7T represents a novel genus and species, for which the name Flavicella marina gen. nov., sp. nov. is proposed. The type strain of Flavicella marina is 2A-7T ( = NBRC 110145T = KCTC 42197T).

A rod-shaped marine bacterium, designated strain CL-TF09T, isolated from a tidal flat in Ganghwa, Korea, was characterized based on its physiological and biochemical features, fatty acid profile and phylogenetic position. 16S rRNA gene sequence analysis revealed a clear affiliation with the family Flavobacteriaceae. Strain CL-TF09T showed the closest phylogenetic relationship with the genera Tenacibaculum and Polaribacter; sequence similarities between CL-TF09T and the type strains of Tenacibaculum and Polaribacter species ranged from 90·7 to 91·8 %. Cells of strain CL-TF09T were non-motile and grew on solid media as yellow colonies. The strain grew in the presence of 1–5 % sea salts, within a temperature range of 5–30 °C and at pH 7–8. The strain had iso-C15 : 0 3-OH (17·4 %), iso-C15 : 0 (16·7 %), anteiso-C15 : 0 (15·1 %) and iso-C16 : 0 3-OH (13·4 %) as predominant fatty acids. The DNA G+C content was 33·9 mol%. Based on the physiological, fatty acid composition and phylogenetic data presented, strain CL-TF09T is considered to represent a novel genus and species of the family Flavobacteriaceae, for which the name Lutibacter litoralis gen. nov., sp. nov. is proposed. The type strain is CL-TF09T (=KCCM 42118T=JCM 13034T).

Sequence Similarities

A Gram-stain-negative, rod-shaped, non-spore-forming bacterium (strain JM-1396T) producing a yellow pigment, was isolated from the healthy internal stem tissue of post-harvest cotton (Gossypium hirsutum, cultivar ‘DES-119’) grown at the Plant Breeding Unit at the E. V. Smith Research Center in Tallassee (Macon county), AL, USA. 16S rRNA gene sequence analysis of strain JM-1396T showed high sequence similarity values to the type strains of Novosphingobium mathurense, Novosphingobium panipatense (both 98.6 %) and Novosphingobium barchaimii (98.5 %); sequence similarities to all other type strains of species of the genus Novosphingobium were below 98.3 %. DNA–DNA pairing experiments of the DNA of strain JM-1396T and N. mathurense SM117T, N. panipatense SM16T and N. barchaimii DSM 25411T showed low relatedness values of 8 % (reciprocal 7 %), 24 % (reciprocal 26 %) and 19 % (reciprocal 25 %), respectively. Ubiquinone Q-10 was detected as the dominant quinone; the fatty acids C18 : 1ω7c (71.0 %) and the typical 2-hydroxy fatty acid, C14 : 0 2-OH (11.7 %), were detected as typical components. The polar lipid profile contained the diagnostic lipids diphosphatidylglycerol, phosphatidylethanolamine, sphingoglycolipid and phosphatidylcholine. The polyamine pattern contained the major compound spermidine and only minor amounts of other polyamines. All these data revealed that strain JM-1396T represents a novel species of the genus Novosphingobium. For this reason we propose the name Novosphingobium gossypii sp. nov. with the type strain JM-1396T ( = LMG 28605T = CCM 8569T = CIP 110884T).

A Gram-positive, non-motile, coccoid- to rod-shaped, non-spore-forming bacterium, designated strain YM18-15T, was isolated from sea sand and studied using a polyphasic taxonomic approach. Strain YM18-15T grew under both aerobic and anaerobic conditions. The cell-wall peptidoglycan type was A4β and ornithine was the diagnostic diamino acid. The polar lipids were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylinositol and an unknown phospholipid, MK-8(H4) was the major menaquinone and the predominant fatty acids were anteiso-C15 : 0 and C16 : 0. The DNA G+C content was 74.2 mol%. High 16S rRNA gene sequence similarities (96.3–97.3 %) were found with the sequences of the type strains of the three genera of the family Beutenbergiaceae. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain YM18-15T formed a clade with Serinibacter salmoneus, Salana multivorans and Beutenbergia cavernae. Strain YM18-15T differed from these three type strains in chemotaxonomic characteristics and in 16S rRNA gene signature nucleotides. Based on genetic and chemotaxonomic evidence, it is suggested that strain YM18-15T represents a novel species of a new genus within the family Beutenbergiaceae, for which the name Miniimonas arenae gen. nov., sp. nov. is proposed. The type strain of the type species is YM18-15T (=NBRC 106267T=KCTC 19750T=MBIC 08348T).

A Gram-positive, aerobic, rod-shaped bacterial strain, 5116S-4T, was isolated from an air sample collected in Suwon city, Republic of Korea. Phylogenetic analysis based on 16S rRNA gene sequences indicated that this strain was a new member of the family Microbacteriaceae . The sequence similarities of this strain to the members of the family Microbacteriaceae were less than 97 %, with the highest values observed with Cryobacterium mesophilum MSL-15T (96.3 %), Cryobacterium roopkundense RuGl7T (96.2 %), Labedella gwakjiensis KSW2-17T (96.2 %), Cryobacterium luteum Hh15T (96.2 %), Cryobacterium psychrophilum DSM 4854T (96.2 %), Klugiella xanthotipulae 44C3T (96.0 %) and Amnibacterium kyonggiense KSL51201-037T (96.0 %). According to the phylogenetic tree, strain 5116S-4T formed a cluster with A. kyonggiense KSL51201-037T, Labedella gwakjiensis KSW2-17T and Lysinimonas soli SGM3-12T (95.3 % sequence similarity) on the support of high bootstrap values. Cells were motile with single polar flagellum and showed optimum growth at 30 °C and pH 7 without NaCl. Predominant cellular fatty acids were anteiso-C15 : 0, iso-C16 : 0 and anteiso-C17 : 0. Polar lipids were diphosphatidylglycerol, dimannosyldiacylglycerol, phosphatidylglycerol, one unknown glycolipid, one unknown phospholipid and one unknown lipid. The acyl type of the cell-wall muramic acid was the acetyl type. Peptidoglycan was supposed to be the type B1 with 2,4-diaminobutyric acid on position 3. Strain 5116S-4T was clearly distinguishable from the phylogenetically related genera in the family Microbacteriaceae in terms of chemotaxonomic characteristics. On the basis of the chemotaxonomic and phylogenetic characteristics, a novel genus and species are proposed, Naasia aerilata gen. nov., sp. nov. The type strain of Naasia aerilata is 5116S-4T ( = KACC 15517T  = NBRC 108725T).

The alphaproteobacterial strains GRP21T and PH34, which were isolated from coastal sediment of the East Sea, Korea, were subjected to a polyphasic taxonomic investigation. The strains were Gram-negative, non-motile, non-spore-forming, oval-shaped rods that produced creamy-white colonies on tryptic soy agar, required NaCl for growth, contained Q-10 as the predominant ubiquinone, contained 16 : 0, 18 : 1ω7c and 19 : 0 cyclo ω8c as major fatty acids and had polar lipid profiles consisting of phosphatidylcholine, phosphatidylglycerol, an unknown aminolipid, an unknown phospholipid and three unknown lipids. Phylogenetic analysis, based on 16S rRNA gene sequencing, showed that the strains were most closely related to Donghicola eburneus KCTC 12735T, with 94.5 % sequence similarity, but formed a separate lineage within the family Rhodobacteraceae. The combined genotypic and phenotypic data supported the conclusion that the strains represent a novel genus and species, for which the name Pontibaca methylaminivorans gen. nov., sp. nov. is proposed. The type strain of Pontibaca methylaminivorans is GRP21T (=KCTC 22497T =DSM 21219T).

A novel, yellow-pigmented actinobacterium was isolated from a small stone collected in Jeju, Republic of Korea. The cells of the organism, designated strain R-Ac013T, were Gram-positive, aerobic, non-motile cocci that occurred singly or in pairs. The strain showed growth at 10–37 °C and pH 4.1–11.1, and tolerated 2 % NaCl. On the basis of the 16S rRNA gene sequence, the organism was phylogenetically related to members of the genera Tetrasphaera (94.6–97.1 % sequence similarity), Terrabacter (96.5 %), Knoellia (96.4 %), Terracoccus (96.4 %), Oryzihumus (96.4 %), Janibacter (96.1–96.4 %) and Intrasporangium (96.2 %). The chemotaxonomic results for the organism were as follows: ll-diaminopimelic acid as the diagnostic diamino acid in the peptidoglycan, acetyl-type murein, MK-8(H4) as the major menaquinone, a DNA G+C content of 74.1 mol%, and a polar lipid profile that comprised diphosphatidylglycerol and phosphatidylinositol. The fatty acid profile consisted of iso- and anteiso-methyl-branched, straight-chain saturated and monounsaturated types, the major components being iso-C16 : 0, C17 : 1 ω8c and iso-C15 : 0. The combination of the phenotypic and phylogenetic data revealed that this strain represents a novel genus and species of the family Intrasporangiaceae, for which the name Lapillicoccus jejuensis gen. nov., sp. nov. is proposed. The type strain is strain R-Ac013T (=KCTC 19200T=DSM 18607T).

A novel filamentous bacterium, designated NariEXT, was isolated from soil collected from Chott Melghir salt lake, which is located in the south-east of Algeria. The strain was an aerobic, halotolerant, thermotolerant, Gram-positive bacterium that was able to grow in NaCl concentrations up to 21 % (w/v), at 37–60 °C and at pH 5.0–9.5. The major fatty acids were iso- and anteiso-C15 : 0. The DNA G+C content was 47.3 mol%. The major menaquinone was MK-7, but MK-6 and MK-8 were also present. The polar lipid profile consisted of phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylmonomethylethanolamine (methyl-PE). Results of molecular and phenotypic analysis led to the description of the strain as a new member of the family Thermoactinomycetaceae . The isolate was distinct from members of recognized genera of this family by morphological, biochemical and chemotaxonomic characteristics. Strain NariEXT showed 16S rRNA gene sequence similarities of 95.38 and 94.28 % with the type strains of Desmospora activa and Kroppenstedtia eburnea , respectively, but differed from both type strains in its sugars, polar lipids and in the presence of methyl-PE. On the basis of physiological and phylogenetic data, strain NariEXT represents a novel species of a new genus of the family Thermoactinomycetaceae for which the name Melghirimyces algeriensis gen. nov., sp. nov. is proposed. The type strain of Melghirimyces algeriensis, the type species of the genus, is NariEXT ( = DSM 45474T = CCUG 59620T).

A rod-shaped, non-spore-forming, non-motile, aerobic, oxidase and catalase-positive and radiation-resistant bacterium (designated strain K4.1T) was isolated from biofilm collected from a Finnish paper mill. The bacterium grew as pale pink colonies on oligotrophic medium at 12 to 50 °C (optimum 37 to 45 °C) and at pH 6 to 10.3. The DNA G+C content of the strain was 66.8 mol%. According to 16S rRNA gene sequence analysis, strain K4.1T was distantly related to the genus Deinococcus, sharing highest similarity with Deinococcus pimensis (90.0 %). In the phylogenetic tree, strain K4.1T formed a separate branch in the vicinity of the genus Deinococcus. The peptidoglycan type was A3β with l-Orn–Gly–Gly and the quinone system was determined to be MK-8. The polar lipid profile of strain K4.1T differed markedly from that of the genus Deinococcus. The predominant lipid of strain K4.1T was an unknown aminophospholipid and it did not contain the unknown phosphoglycolipid predominant in the polar lipid profiles of deinococci analysed to date. Two of the predominant fatty acids of the strain, 15 : 0 anteiso and 17 : 0 anteiso, were lacking or present in small amounts in species of the genus Deinococcus. Phylogenetic distinctness and significant differences in the polar lipid and fatty acid profiles suggest classification of strain K4.1T as a novel genus and species in the family Deinococcaceae, for which we propose the name Deinobacterium chartae gen. nov., sp. nov. The type strain is K4.1T (=DSM 21458T =HAMBI 2721T).
