This article introduces a new Staphylococcus species cultivated from a human foot wound infection in a Dutch traveller returning from the island of Bali, Indonesia: Staphylococcus roterodami sp. nov. Based on the genomic sequence, there is strong molecular evidence for assigning the strain to a novel species within the S. aureus complex. Differences in cellular fatty acid spectrum and biochemical tests underline these findings. Its ecological niche and pathogenicity require further study. The type strain is DSM111914T (JCM34415T).

Two strains (JA575T and JA576T) of orange- to pink-pigmented, rod-shaped, motile and budding phototrophic bacteria were isolated from paddy soils. Both strains contained bacteriochlorophyll a and carotenoids of spirilloxanthin series. Both strains had C18 : 1ω7c as the major cellular fatty acid, ubiquinone-10 (Q10) as the main quinone, and diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and phosphatidylcholine as polar lipids. Phylogenetic analysis on the basis of 16S rRNA gene sequences showed that both strains clustered with species of the genus Rhodopseudomonas in the class Alphaproteobacteria . Strains JA575T and JA576T were genotypically (<35 % DNA–DNA relatedness) and phenotypically distinct from each other. Further, both strains showed less than 48 % DNA–DNA relatedness with the type strains of all recognized species of the genus Rhodopseudomonas . The molecular evidence is supported by phenotypic evidence. It is proposed that strains JA575T and JA576T be classified as representing two novel species of the genus Rhodopseudomonas with the species names Rhodopseudomonas pentothenatexigens sp. nov. and Rhodopseudomonas thermotolerans sp. nov., respectively. The type strains of the proposed novel species are JA575T ( = NBRC 108862T = KCTC15143T) and JA576T ( = NBRC 108863T = KCTC 15144T), respectively.

A novel species within the genus Eikenella is described, based on the phenotypical, biochemical and genetic characterization of a strain of a facultatively anaerobic, Gram-negative rod-shaped bacterium. Strain S3360T was isolated from the throat swab of a patient sampled during routine care at a hospital. Phylogenetic analyses (full-length 16S rRNA gene and whole-genome sequences) placed the strain in the genus Eikenella , separate from all recognized species but with the closest relationship to Eikenella longinqua (NML 02-A-017T). Eikenella is one of the genera in the HACEK group known to be responsible for rare cases of endocarditis in humans. Until the recent descriptions of Eikenella exigua , Eikenella halliae and Eikenella longinqua , Eikenella corrodens had been the only validly published species in this genus since its description as Bacteroides corrodens in 1958. Unlike these species, strain S3360T is able to metabolize carbohydrates (glucose). The average nucleotide identities of strain S3360T with E. longinqua (NML 02-A-017T) and E. corrodens (NCTC 10596T), the type species of the genus, were 90.5 and 84.7 %, respectively, and the corresponding genome-to-genome distance values were 41.3 and 29.0 %, respectively. The DNA G+C content of strain S3360T was 58.4 mol%. Based on the phenotypical, biochemical and genetic findings, strain S3360T is considered to represent a novel species within the genus Eikenella , for which the name Eikenella glucosivorans sp. nov. is proposed. The type strain is S3360T (DSM 110714T=CCOS 1935T=CCUG 74293T). In addition, an emendation of the genus Eikenella is proposed to include species which are saccharolytic.

A novel thermotolerant bacterium, designated SgZ-8T, was isolated from a compost sample. Cells were non-motile, endospore-forming, Gram-staining positive, oxidase-negative and catalase-positive. The isolate was able to grow at 20–65 °C (optimum 50 °C) and pH 6.0–9.0 (optimum 6.5–7.0), and tolerate up to 9.0 % NaCl (w/v) under aerobic conditions. Anaerobic growth occurred with anthraquinone-2,6-disulphonate (AQDS), fumarate and NO3 - as electron acceptors. Phylogenetic analysis based on the16S rRNA and gyrB genes grouped strain SgZ-8T into the genus Bacillus , with the highest similarity to Bacillus badius JCM 12228T (96.2 % for 16S rRNA gene sequence and 83.5 % for gyrB gene sequence) among all recognized species in the genus Bacillus . The G+C content of the genomic DNA was 49.3 mol%. The major isoprenoid quinone was menaquinone 7 (MK-7) and the polar lipids consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and an unidentified phospholipid. The major cellular fatty acid was iso-C16 : 0. On the basis of its phenotypic and phylogenetic properties, chemotaxonomic analysis and the results of physiological and biochemical tests, strain SgZ-8T ( = CCTCC AB 2012108T = KACC 16706T) was designated the type strain of a novel species of the genus Bacillus , for which the name Bacillus thermotolerans sp. nov. is proposed.

A Gram-stain-negative, facultatively anaerobic, non-motile and coccoid- to short-rod-shaped bacterium, designated strain Dys-CH1T, was isolated from the hindgut of a fungus-growing termite Macrotermes barneyi. The optimal pH and cultivation temperature of strain Dys-CH1T were pH 7.2–7.6 and 35–37 °C, respectively. Sequence analysis of 16S rRNA gene showed that Dys-CH1T shared 94.6 % and 90.9 % similarity with Dysgonomonas capnocytophagoides JCM 16697T and Dysgonomonas gadei CCUG 42882T, respectively. Strain Dys-CH1T was found to be different from other species of the genus Dysgonomonas with validly published names with respect to taxonomically important traits, including habitat, biochemical tests, DNA G+C content, bile resistance, fatty-acid composition and susceptibility to antimicrobial agents. On the basis of these characteristics, strain Dys-CH1T represents a novel species of the genus Dysgonomonas for which the name Dysgonomonas macrotermitis sp. nov. is proposed. The type strain is Dys-CH1T ( = JCM 19375T = DSM 27370T).

A Gram-stain-positive, obligately anaerobic, short rod, designated strain HHRM1715T, was isolated from the blood of a patient with Fournier’s gangrene, complicated by sepsis. On the basis of 16S rRNA gene sequence analysis, strain HHRM1715T was shown to belong to the genus Atopobium and was most closely related to Atopobium minutum (95 % similarity). The results of 16S rRNA-gene-based phylogenetic analysis, cellular fatty acid analysis and differential biochemical tests, showed that strain HHRM1715T represented a novel species of the genus Atopobium . We therefore describe Atopobium deltae sp. nov. with HHRM1715T ( = LMG 27987T = CCUG 65171T) as the type strain and propose an emended description of the genus Atopobium with regard to the DNA G+C content.

One thermophilic bacterium, designated strain SYSU G02662T, was isolated from hot spring sediment sampled in Tibet, PR China. Polyphasic taxonomic analyses and whole-genome sequencing were used to determine the taxonomy position of the strain. Phylogenetic analysis using 16S rRNA gene sequences indicated that strain SYSU G02662T showed the highest sequence similarity to Actinomarinicola tropica SCSIO 58843T (95.1 %). The strain could be differentiated from other species of the family Iamiaceae by its distinct phenotypic and genotypic characteristics. Cells of strain SYSU G02662T were aerobic, Gram-staining-positive and short rodshaped. Growth occurred optimally at 45 °C and pH 7.0. In addition, meso-diaminopimelic acid was the diagnostic diamino acid in the cell-wall peptidoglycan. The respiratory quinone was MK-9 (H8), while the major fatty acids (>10 %) were C16 : 0, C17 : 0, C18 : 0 and iso-C16 : 0. The detected polar lipids included diphosphatidylglycerol, phosphatidylinositol mannoside and phosphatidylinositol. The G+C content of the genomic DNA was 70.5 % based on the draft genomic sequence. On the basis of phenotypic, genotypic and phylogenetic data, strain SYSU G02662T represents a novel species of a novel genus in the family Iamiaceae , for which the name Rhabdothermincola sediminis gen. nov., sp. nov. is proposed. The type strain of the proposed novel species is SYSU G02662T (=CGMCC 4.7688T=KCTC 49500T).

A novel bacterial strain, designated DCY54T, was isolated from a field cultivated with ginseng in Yongin, Republic of Korea. Cells were Gram-reaction-negative, yellow-pigmented, rod-shaped, non-spore-forming, and strictly aerobic. They were motile by gliding and produced flexirubin-type pigments. Growth occurred optimally at 25–30 °C, at pH 5.0–7.0 and in the presence of 0–1 % NaCl. The 16S rRNA sequence analysis demonstrated that strain DCY54T was most closely related to Flavobacterium defluvii EMB117T (96.9 %). The only isoprenoid quinone of strain DCY 54T was menaquinone-6 (MK-6) and the major polar lipids were phosphatidylethanolamine, one unidentified aminolipid and one unidentified lipid. The major cellular fatty acids (>15 %) were iso-C15 : 0, summed feature 3 (comprising C16 : 1ω7c and/or iso-C15 : 0 2-OH) and C16 : 0. The DNA G+C content was 33.3 mol%. Phylogenetic inference and phenotypic data supported affiliation of strain DCY54T to the genus Flavobacterium . Several physiological and biochemical tests differentiated strain DCY54T from the species of the genus Flavobacterium with validly published names. On the basis of data from a polyphasic study, strain DCY54T represents a novel species of the genus Flavobacterium for which the name Flavobacterium ginsengisoli sp. nov. is proposed. The type strain is DCY54T ( = KCTC 23318T = JCM 17336T).

A Gram-reaction-negative, aerobic, non-flagellated, rod-shaped bacterium, designated strain SM1211T, was isolated from Antarctic seawater. The isolate grew at 4–35 °C and with 0–10 % (w/v) NaCl. It could produce bacteriochlorophyll a, but did not reduce nitrate to nitrite or hydrolyse DNA. Phylogenetic analysis of 16S rRNA gene sequences revealed that strain SM1211T constituted a distinct phylogenetic line within the family Rhodobacteraceae and was closely related to species in the genera Litorimicrobium , Leisingera , Seohaeicola and Phaeobacter with 95.1–96.0 % similarities. The predominant cellular fatty acid was C18 : 1ω7c. The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, an unidentified aminolipid and two unidentified phospholipids. The genomic DNA G+C content of strain SM1211T was 60.7 mol%. Based on the phylogenetic, chemotaxonomic and phenotypic data obtained in this study, strain SM1211T is considered to represent a novel species in a new genus within the family Rhodobacteraceae , for which the name Puniceibacterium antarcticum gen. nov., sp. nov. is proposed. The type strain of Puniceibacterium antarcticum is SM1211T ( = CCTCC AB 2013147T = KACC 16875T).

Three rod-shaped halophilic archaeal strains, DL-M4T, LYG-109 and DLLS-108T, were isolated from the salted brown alga Laminaria produced in different marine areas of PR China. Cells of strains were motile, formed red-pigmented colonies on agar and lysed in distilled water. The three strains grew optimally with 2.6 M NaCl, with 0.05–0.3 M MgCl2, at 37 °C and at pH 7.0–7.5. The results of phylogenetic analyses based on the 16S rRNA and rpoB′ genes differentiated these strains into two clusters belonging to the genus Halostella , which currently contains Halostella salina CBA1114T and Halostella limicola LT12T. Strains DL-M4T and LYG-109 formed a single cluster separate from the current two members of Halostella (94.4–95.7 and 90.0–90.9 % similarities, respectively) while strain DLLS-108T had Hsl. salina CBA1114T as its nearest neighbour (97.7–97.8 and 95.9 % similarities, respectively) and was separated from Hsl. limicola LT12T (94.4–95.8 and 93.4 % similarities, respectively). These clusters represented two distinct novel species as indicated by phenotypic characteristics, polar lipid compositions and whole-genome comparisons. Diverse phenotypic characteristics, morphology and growth characteristics, nutrition and miscellaneous biochemical tests differentiate strains DL-M4T, LYG-109, DLLS-108T from Hsl. limicola LT12T and Hsl. salina CBA1114T. Strains DL-M4T and LYG-109 contained phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester and three unidentified glycolipids, while strain DLLS-108T contained these polar lipids and two unidentified phospholipids. The major respiratory quinones detected in the three isolates were menaquinone MK-8 and MK-8(H2). The average nucleotide identity (ANI) and in silico DNA–DNA hybridization (isDDH) values between the isolated strains and the current two members of Halostella were found to be 79.3–86.6 (ANI) and 22.9–49.8 % (isDDH). All these results showed that the three isolates represent two novel species of the genus Halostella for which the names Halostella pelagica sp. nov. [type strain dl-M4T (=CGMCC 1.13603T=JCM 32954T)] and Halostella litorea sp. nov. [type strain DLLS-108T(=CGMCC 1.13610T=JCM 32955T)] are proposed.

The taxonomic status of six strains of Acinetobacter obtained from meat samples, collected from supermarkets in Porto, Portugal, was investigated using polyphasic analysis. Partial rpoB sequence similarities lower than 95 % to other Acinetobacter species with validly published names led to the hypothesis that these strains represented novel species. This was confirmed based on comparative multilocus sequence analysis, which included the gyrB, recA and 16S rRNA genes, revealing that these strains represented two coherent lineages that were distinct from each other and from all known species. The names Acinetobacter portensis sp. nov. (comprising four strains) and Acinetobacter guerrae sp. nov. (comprising two strains) are proposed for these novel species. The species status of these two groups was confirmed by low (below 95 %) whole-genome sequence average nucleotide identity values and low (below 70 %) digital DNA–DNA hybridization similarities between the whole-genome sequences of the proposed type strains of each novel species and the representatives of the known Acinetobacter species. Phylogenomic treeing from core genome analysis supported these results. The coherence of each new species lineage was supported by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry differentiation of the species at the protein level, by cellular fatty acid profiles, and by unique and differential combinations of metabolic and physiological properties shared by each novel species. The type strain of A. portensis sp. nov. is AC 877T (=CCUG 68672T=CCM 8789T) and the type strain of A. guerrae sp. nov. is AC 1271T (=CCUG 68674T=CCM 8791T).
