A novel Gram-stain-negative, aerobic, yellow-pigmented bacterium was isolated from seawater of Aoshan Bay, and designated as strain ASW18T. Strain ASW18T was a long-rod-shaped bacterium without flagellum and lacked gliding ability. Based on 16S rRNA gene phylogeny, strain ASW18T showed the closest relationship to Croceivirga radicis MCCC 1A06690T, with a sequence similarity of 97.0 %. Strain ASW18T was able to grow at 25–40 °C, at pH 5.5–9.5 and with 0.5–9 % (w/v) NaCl. The genomic DNA G+C content of strain ASW18T was 37.3 %. The predominant cellular fatty acids of strain ASW18T were iso-C15 : 0, iso-C17 : 0 3-OH and iso-C15 : 1 G. The major polar lipids were phosphatidylethanolamine, phosphatidyldimethylethanolamine, an aminolipid and three unidentified lipids. The respiratory quinone of strain ASW18T was menaquinone with six isoprene units (MK-6). Based on the present polyphasic analysis, strain ASW18T represents a novel species of the genus Croceivirga , for which the name Croceivirga litoralis sp. nov. is proposed; the type strain is ASW18T (=MCCC 1K04203T=KCTC 72852T). In addition, it is also proposed that Muricauda lutea should be reclassified as Croceivirga lutea comb. nov.; the type strain is CSW06T (=CGMCC 1.15761T=JCM 31455T=KCTC 52375T=MCCC 1K03195T).

Four unknown strains belonging to the genus Arthrobacter were isolated from plateau wildlife on the Qinghai–Tibet Plateau of PR China. Phylogenetic analysis based on 16S rRNA gene sequences showed that the four isolates were separated into two clusters. Cluster I (strains 785T and 208) had the greatest 16S rRNA gene sequence similarity to Arthrobacter citreus (98.6 and 98.7 %, respectively), Arthrobacter luteolus (98.0 and 98.1%, respectively), Arthrobacter gandavensis (97.9 and 98.0 %, respectively) and Arthrobacter koreensis (97.6 and 97.7 %, respectively). Likewise, cluster II (strains J391T and J915) had the highest sequence similarity to Arthrobacter ruber (98.6 and 98.3 %, respectively) and Arthrobacter agilis (98.1 and 97.9  %, respectively). Average nucleotide identity and the digital DNA–DNA hybridization values illustrated that the two type strains, 785T and J391T, represented two separate novel species that are distinct from all currently recognized species in the genus Arthrobacter . These strains had DNA G+C contents of 66.0–66.1 mol% (cluster I) and 68.0 mol% (cluster II). The chemotaxonomic properties of strains 785T and J391T were in line with those of the genus Arthrobacter : anteiso-C15:0 (79.3 and 40.8 %, respectively) as the major cellular fatty acid, MK-8(H2) (65.8 %) or MK-9(H2) (75.6 %) as the predominant respiratory quinone, a polar lipid profile comprising diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, glycolipids and phospholipid, and A3α or A4α as the cell wall peptidoglycan type. On the basis of our results, two novel species in the genus Arthrobacter are proposed, namely Arthrobacter yangruifuii sp. nov. (type strain, 785T=CGMCC 1.16725T=GDMCC 1.1592T=JCM 33491T) and Arthrobacter zhaoguopingii sp. nov. (type strain, J391T=CGMCC 1.17382T=GDMCC 1.1667T=JCM 33841T).

A polyphasic analysis was undertaken of seven independent isolates of Gram-negative cocci collected from pathological clinical samples from New York, Louisiana, Florida and Illinois and healthy subgingival plaque from a patient in Virginia, USA. The 16S rRNA gene sequence similarity among these isolates was 99.7–100 %, and the closest species with a validly published name was Neisseria lactamica (96.9 % similarity to the type strain). DNA–DNA hybridization confirmed that these isolates are of the same species and are distinct from their nearest phylogenetic neighbour, N. lactamica . Phylogenetic analysis of 16S and 23S rRNA gene sequences indicated that the novel species belongs in the genus Neisseria . The predominant cellular fatty acids were C16 : 0, summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH) and C18 : 1ω7c. The cellular fatty acid profile, together with other phenotypic characters, further supports the inclusion of the novel species in the genus Neisseria . The name Neisseria oralis sp. nov. (type strain 6332T  = DSM 25276T  = LMG 26725T) is 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).

Two Gram-stain-negative, aerobic, non-motile bacterial strains, 36D10-4-7T and 30C10-4-7T, were isolated from bark canker tissue of Populus × euramericana, respectively. 16S rRNA gene sequence analysis revealed that strain 36D10-4-7T shows 98.0 % sequence similarity to Sphingomonas adhaesiva DSM 7418T, and strain 30C10-4-7T shows highest sequence similarity to Sphingobacterium arenae H-12T (95.6 %). Average nucleotide identity analysis indicates that strain 36D10-4-7T is a novel member different from recognized species in the genus Sphingomonas . The main fatty acids and respiratory quinone detected in strain 36D10-4-7T are C18 : 1  ω7c and/or C18 : 1  ω6c and Q-10, respectively. The polar lipids are diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol, aminolipid, phosphatidylethanolamine, sphingoglycolipid, two uncharacterized phospholipids and two uncharacterized lipids. For strain 30C10-4-7T, the major fatty acids and menaquinone are iso-C15 : 0, C16 : 1  ω7c and/or C16 : 1  ω6c and iso-C17 : 0 3-OH and MK-7, respectively. The polar lipid profile includes phosphatidylethanolamine, phospholipids, two aminophospholipids and six unidentified lipids. Based on phenotypic and genotypic characteristics, these two strains represent two novel species within the genera Sphingomonas and Sphingobacterium . The name Sphingomonas corticis sp. nov. (type strain 36D10-4-7T=CFCC 13112T=KCTC 52799T) and Sphingobacterium corticibacterium sp. nov. (type strain 30C10-4-7T=CFCC 13069T=KCTC 52797T) are proposed.

A strictly aerobic, bacteriochlorophyll (BChl) a-containing alphaproteobacterium, designated strain K6T, was isolated from seawater around an aquaculture site in the Uwa Sea in Japan. The novel strain grew optimally at 30 °C at pH 7.0–7.5 and in the presence of 2.0 % (w/v) NaCl. The nonmotile and coccoid or rod-shaped cells formed pink-pigmented colonies on agar plates containing organic compounds. Cells showed an in vivo absorption maximum at 870 nm in the near-infrared region, indicating the presence of BChl a in the light-harvesting 1 complex. The new bacterial strain was Gram-stain-negative and oxidase- and catalase-positive. Phylogenetic analysis based on the 16S rRNA gene sequence showed that strain K6T was closely related to species in the genus Litoreibacter . The closest phylogenetic relatives of strain K6T were Litoreibacter ponti GJSW-31T (98.56 % sequence similarity), Litoreibacter janthinus KMM 3842T (97.63 %) and Litoreibacter albidus KMM 3851T (96.88 %). The G+C content of the genomic DNA was 58.26 mol%. The average nucleotide identity value of strain K6T with the type strain of L. ponti was 77.16 % (SD 4.79 %). The digital DNA−DNA hybridization value of strain K6T with the type strain of L. ponti was 19.40 %. The respiratory quinone was ubiquinone-10. The major cellular fatty acids were C18 : 1 ω7c, C16 : 0 and 11-methyl C18 : 1 ω7c. The dominant polar lipids were phosphatidylcholine and phosphatidylglycerol. On the basis of the genetic and phenotypic data obtained in the present study, we propose a new species in the genus Litoreibacter : Litoreibacter roseus sp. nov., whose type strain is K6T (=DSM 110109T=NBRC 114114T). Strain K6T represents the first confirmed species that produces BChl a within the genus Litoreibacter .

A Gram-reaction-negative, motile, non-violet-pigmented, rod-shaped bacterial strain, designated E1T, was isolated from Arctic lake sediment. Growth occurred at 4 °C–28 °C (optimum, 18 °C), at pH 4–11(optimum, 9–10) and in the presence of 0–1 % (w/v) NaCl. The taxonomic position of E1T was analysed using a polyphasic approach. Strain E1T exhibited 16S rRNA gene sequence similarity value of 98.1 % with respect to the type strain of Iodobacter fluviatilis , but no more than 93 % with the type strains of other recognized species. A further DNA–DNA hybridization experiment was conducted, which demonstrated unambiguously that strain E1T was distinct from I. fluviatilis ATCC 33051T (51.3 % relatedness). The DNA G+C content of strain E1T was 52.3 mol%. Chemotaxonomic data [Q-8 as the monospecific respiratory quinone and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c, 56.1 %) and C16 : 0 (18.8 %) as the major cellular fatty acids] supported the affiliation of strain E1T to the genus Iodobacter . However, the results of physiological and biochemical tests allowed phenotypic differentiation of strain E1T from I. fluviatilis ATCC 33051T. On the basis of phenotypic and genotypic properties, strain E1T represents a novel species of genus Iodobacter, for which the name Iodobacter limnosediminis sp. nov. is proposed. The type strain is E1T ( = CCTCC AB 2010224T = NRRL B-59456T).

Two novel Gram-staining-negative, aerobic, cocci-shaped, non-motile, non-spore forming, pink-pigmented bacteria designated strains T6T and T18T, were isolated from a biocrust (biological soil crust) sample from the vicinity of the Tabernas Desert (Spain). Both strains were catalase-positive and oxidase-negative, and grew under mesophilic, neutrophilic and non-halophilic conditions. According to the 16S rRNA gene sequences, strains T6T and T18T showed similarities with Belnapia rosea CGMCC 1.10758T and Belnapia moabensis CP2CT (98.11 and 98.55% gene sequence similarity, respectively). The DNA G+C content was 69.80 and 68.96% for strains T6T and T18T, respectively; the average nucleotide identity by blast (ANIb) and digital DNA–DNA hybridization (dDDH) values confirmed their adscription to two novel species within the genus Belnapia . The predominant fatty acids were summed feature 8 (C18 : 1ω7c/C18 : 1ω6c), C16 : 0, C18 : 1 2-OH and summed feature 3 (C16 : 1ω7c/C16 : 1ω6c). According to he results of the polyphasic study, strains T6T and T18T represent two novel species in the genus Belnapia (which currently includes only three species), for which names Belnapia mucosa sp. nov. (type strain T6T = CECT 30228T=DSM 112073T) and Belnapia arida sp. nov. (type strain T18T=CECT 30229T=DSM 112074T) are proposed, respectively.

Two strains of the family Rhodospirillaceae were isolated from the rhizosphere of the medicinal plant Hypericum perforatum. Cells of both strains were Gram-stain-negative, motile by means of a single polar flagellum, non-spore-forming, non-capsulated, short rods that divided by binary fission. Colonies were small and white. Strains R5913T and R5959T were oxidase-positive, mesophilic, neutrophilic and grew optimally without NaCl. Both grew under aerobic and microaerophilic conditions and on a limited range of substrates with best results on yeast extract. Major fatty acids were C19 : 0 cyclo ω8c and C16 : 0; in addition, C18 : 1ω7c was also found as a predominant fatty acid in strain R5913T. The major respiratory quinone was ubiquinone 10 (Q-10). The DNA G+C contents of strains R5913T and R5959T were 66.0 and 67.4 mol%, respectively. 16S rRNA gene sequence comparison revealed that the closest relatives (<92 % similarity) of the strains are Oceanibaculum pacificum MCCC 1A02656T, Dongia mobilis CGMCC 1.7660T, Dongia soli D78T and Dongia rigui 04SU4-PT. The two novel strains shared 98.6 % sequence similarity and represent different species on the basis of low average nucleotide identity of their genomes (83.8 %). Based on the combined phenotypic, genomic and phylogenetic investigations, the two strains represent two novel species of a new genus in the family Rhodospirillaceae , for which the name Hypericibacter gen. nov. is proposed, comprising the type species Hypericibacter terrae sp. nov. (type strain R5913T=DSM 109816T=CECT 9472T) and Hypericibacter adhaerens sp. nov. (type strain R5959T=DSM 109817T=CECT 9620T).

A novel rod-shaped and Gram-stain-negative bacterium, designated strain RZ05T, was isolated from a sand sample collected from the intertidal zone of the Yellow Sea, PR China. Results of phylogenetic analysis based on 16S rRNA gene sequences revealed that strain RZ05T clusters within the genus Maribacter , a member of the family Flavobacteriaceae , and has the highest sequence similarity to Maribacter polysiphoniae KCTC 22021T (97.8 %), followed by Maribacter arenosus KCTC 52191T (97.2 %). Cells of this strain were observed to be aerobic, oxidase- and catalase-positive, motile by gliding and formed yellow colonies. Growth occurred at 7–40 °C (optimum, 30 °C), at pH 6.5–9.5 (optimum, pH 7.0) and with 0.5–6 % (optimum, 2 %) NaCl. Its polar lipid profile included phosphatidylethanolamine, two unidentified glycolipids, one unidentified aminolipid and four unidentified lipids. The major cellular fatty acids were iso-C15 : 0, iso-C15 : 1 G, iso-C17 : 0 3-OH, iso-C16 : 0 3-OH, iso-C15 : 0 3-OH, summed feature 9 (10-methyl C16 : 0/iso-C17 : 1  ω9c) and summed feature 3 (iso-C15 : 0 2-OH/C16 : 1  ω7c/C16 : 1  ω6c). The only respiratory quinone was menaquinone 6 (MK-6). The genome of strain RZ05T was 4.65 Mbp with a G+C content of 38.9 mol%. The average nucleotide identity and in silico DNA–DNA hybridization values between strain RZ05T and its most closely related type strain M. polysiphoniae KCTC 22021T were 80.3 and 26.3  %, respectively. The results of phylogenetic, phenotypic and chemotaxonomic analyses indicated that strain RZ05T represents a novel species of the genus Maribacter , for which the name Maribacter luteus sp. nov. is proposed. The type strain is RZ05T (=KCTC 62834T=MCCC 1K03617T).

As part of a study investigating the microbiome of bee hives and honey, two novel strains (TMW 2.1880T and TMW 2.1889T) of acetic acid bacteria were isolated and subsequently taxonomically characterized by a polyphasic approach, which revealed that they cannot be assigned to known species. The isolates are Gram-stain-negative, aerobic, pellicle-forming, catalase-positive and oxidase-negative. Cells of TMW 2.1880T are non-motile, thin/short rods, and cells of TMW 2.1889T are motile and occur as rods and long filaments. Morphological, physiological and phylogenetic analyses revealed a distinct lineage within the genus Bombella . Strain TMW 2.1880T is most closely related to the type strain of Bombella intestini with a 16S rRNA gene sequence similarity of 99.5 %, and ANIb and in silico DDH values of 94.16 and 56.3 %, respectively. The genome of TMW 2.1880T has a size of 1.98 Mb and a G+C content of 55.3 mol%. Strain TMW 2.1889T is most closely related to the type strain of Bombella apis with a 16S rRNA gene sequence similarity of 99.5 %, and ANIb and in silico DDH values of 85.12 and 29.5 %, respectively. The genome of TMW 2.1889T has a size of 2.07 Mb and a G+C content of 60.4 mol%. Ubiquinone analysis revealed that both strains contained Q-10 as the main respiratory quinone. Major fatty acids for both strains were C16 : 0, C19 : 0 cyclo ω8c and summed feature 8, respectively, and additionally C14 : 0 2-OH only for TMW 2.1880T and C14 : 0 only for TMW 2.1889T. Based on polyphasic evidence, the two isolates from honeycombs of Apis mellifera represent two novel species of the genus Bombella , for which the names Bombella favorum sp. nov and Bombella mellum sp. nov. are proposed. The designated respective type strains are TMW 2.1880T (=LMG 31882T=CECT 30114T) and TMW 2.1889T (=LMG 31883T=CECT 30113T).
