A pleomorphic, Gram-stain-negative, rod-shaped, indole-, oxidase- and catalase-negative, non-spore-forming, non-motile bacterium (strain 131000547T) was isolated from the lungs of a cat with pneumonia. On the basis of 16S rRNA gene sequence analyses the strain was assigned to the genus Streptobacillus with 97.6  % sequence similarity to the type strain of Streptobacillus moniliformis and 94.6  % to that of Streptobacillus hongkongensis. The clear differentiation of strain 131000547T from Streptobacillus moniliformis and Streptobacillus hongkongensis was also supported by gyrB, groEL, and recA nucleotide and amino acid sequence analysis. DNA–DNA hybridization demonstrated ≤ 19.9  % (reciprocal 28.7  %) DNA–DNA relatedness between strain 131000547T and Streptobacillus moniliformis DSM 12112T. Physiological data confirmed the allocation of strain 131000547T to the family Leptotrichiaceae. Strain 131000547T has a unique profile of enzyme activities allowing differentiation from the most closely related species. Within the genus Streptobacillus, isolate 131000547T could also unambiguously be separated from Streptobacillus moniliformis and Streptobacillus hongkongensis by both matrix-assisted laser desorption ionization time-of-flight mass spectrometry and Fourier transform-infrared spectroscopy. On the basis of these data, a novel species of the genus Streptobacillus, Streptobacillus felis sp. nov., is proposed with the type strain 131000547T ( = DSM 29248T = CCUG 66203T = CCM 8542T). Emended descriptions of the genus Streptobacillus and of Streptobacillus moniliformis are also given.

A pleomorphic, Gram-negative, rod-shaped, indole-, oxidase- and catalase-negative, non-spore-forming, non-motile bacterium was isolated in 1979 from the heart of a spinifex hopping mouse (Notomys alexis Thomas, 1922) with septicaemia and stored as Streptobacillus moniliformis in the strain collection of the Animal Health Laboratory, South Perth, Western Australia (AHL 370-1), as well as under CCUG 12425. On the basis of 16S rRNA gene sequence analyses, the strain was assigned to the genus Streptobacillus, with 99.4 % sequence similarity to the type strain of Streptobacillus moniliformis, 95.6 % sequence similarity to the type strain of Streptobacillus hongkongensis and 99.0 % sequence similarity to the type strain of Streptobacillus felis. The clear differentiation of strain AHL 370-1T from Streptobacillus moniliformis, Streptobacillus hongkongensis and Streptobacillus felis was also supported by rpoB, groEL and recA nucleotide and amino acid sequence analysis. Average nucleotide identity was 87.16 % between strain AHL 370-1T and Streptobacillus moniliformis DSM 12112T. Physiological data confirmed the allocation of strain AHL 370-1T to the family Leptotrichiaceae, considering the very similar profiles of enzyme activities and fatty acids compared to closely related species. Within the genus Streptobacillus, isolate AHL 370-1T could also be separated unambiguously from the type strains of Streptobacillus moniliformis, Streptobacillus hongkongensis and Streptobacillus felis by MALDI-TOF mass spectrometry. Two further strains (KWG2 and KWG24) isolated from asymptomatic black rats in Japan were highly similar to AHL 370-1T. On the basis of these data, we propose the novel species Streptobacillus notomytis sp. nov., with the type strain AHL 370-1T ( = CCUG 12425T = DSM 100026T = CCM 8593T = EF 12425T).

A yellow-pigmented, Gram-negative, rod-shaped bacterium (strain CC-YY255T) was isolated from compost generated from food waste collected from Kinmen County, Taiwan. 16S rRNA gene sequence analysis indicated that the strain formed a monophyletic branch at the periphery of the evolutionary radiation occupied by the genus Luteimonas; its closest neighbour was the type strain of Luteimonas mephitis (94.4 % sequence similarity). The isolate was distinguished from Luteimonas mephitis on the basis of several phenotypic properties. The organism utilized glucose, maltose, gentiobiose, melibiose and turanose and only a few organic acids (acetate, propionate) and amino acids (l-alanyl glycine, glycyl l-aspartic acid and glycyl l-glutamic acid) as substrates. The fatty acid profile was slightly different from that reported for Luteimonas mephitis. It is evident from the genotypic, chemotaxonomic and physiological data presented that strain CC-YY255T represents a novel species of the genus Luteimonas, for which the name Luteimonas composti sp. nov. is proposed. The type strain is CC-YY255T (=CCUG 53595T=CIP 109311T=BCRC 17598T).

Three novel endophytic strains, designated 17B10-2-12T, 26C10-4-4 and D13-10-4-9, were isolated from the bark of Populus euramericana in Heze, Shandong Province, China. They were Gram-reaction-negative, aerobic, non-motile, short-rod-shaped, oxidase-positive and catalase-negative. A phylogenetic analysis of the 16S rRNA gene showed that the three novel strains clustered with members of the family Comamonadaceae and formed a distinct branch. The isolates shared 100 % similarities among themselves and had the highest sequence similarity with Xenophilus azovorans DSM 13620T (95.2 %) and Xenophilus arseniciresistens YW8T (95.0 %), and less than 95.0 % sequence similarities with members of other species. Their major fatty acids were C16 : 0, C17 : 0 cyclo, C18 : 1ω7c and C16 : 1ω7c/C16 : 1ω6c. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and three unknown aminophospholipids. The predominant quinone was ubiquinone-8 (Q-8). The DNA G+C content was 69.5–70.0 mol%. Based on data from a polyphasic taxonomy study, the three strains represent a novel species of a novel genus of the family Comamonadaceae, for which the name Corticibacter populi gen. nov., sp. nov. is proposed. The type strain is 17B10-2-12T ( = CFCC 12099T = KCTC 42091T).

AbstractThe gut microbiota is considered to play a key role in human health. As a consequence, deciphering its microbial diversity is mandatory. A polyphasic taxonogenomic strategy based on the combination of phenotypic and genomic analyses was used to characterize a new bacterium, strain Marseille-P2911. This strain was isolated from a left colon sample of a 60-year old man who underwent a colonoscopy for an etiological investigation of iron-deficiency anemia in Marseille, France. On the basis of 16S rRNA sequence comparison, the closest phylogenetic neighbor was Anaeroglobus geminatus (94.59% 16S rRNA gene sequence similarity) within the family Veillonellaceae. Cells were anaerobic, Gram-stain-positive, non-spore-forming, catalase/oxidase negative cocci grouped in pairs. The bacterium was able to grow at 37 °C after 2 days of incubation. Strain Marseille-P2911 exhibited a genome size of 1,715,864-bp with a 50.2% G + C content, and digital DNA-DNA hybridization (dDDH) and OrthoANI values with A. geminatus of only 19.1 ± 4.5% and 74.42%, respectively. The latter value being lower than the threshold for genus delineation (80.5%), we propose the creation of the new genus Colibacter gen. nov., with strain Marseille-P2911T (=DSM 103304 = CSUR P2911) being the type strain of the new species Colibacter massiliensis gen. nov., sp. nov.

A novel brown-coloured, Gram-negative-staining, rod-shaped, motile, phototrophic, purple sulfur bacterium, designated strain AK40T, was isolated in pure culture from a sediment sample collected from Coringa mangrove forest, India. Strain AK40T contained bacteriochlorophyll a and carotenoids of the rhodopin series as major photosynthetic pigments. Strain AK40T was able to grow photoheterotrophically and could utilize a number of organic substrates. It was unable to grow photoautotrophically and did not utilize sulfide or thiosulfate as electron donors. Thiamine and riboflavin were required for growth. The dominant fatty acids were C12 : 0, C16 : 0, C18 : 1ω7c and summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH). The polar lipid profile of strain AK40T was found to contain diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and eight unidentified lipids. Q-10 was the predominant respiratory quinone. The DNA G+C content of strain AK40T was 65.5 mol%. 16S rRNA gene sequence comparisons indicated that the isolate represented a member of the family Chromatiaceae within the class Gammaproteobacteria. 16S rRNA gene sequence analysis indicated that strain AK40T was closely related to Phaeochromatium fluminis, with 95.2 % pairwise sequence similarity to the type strain; sequence similarity to strains of other species of the family was 90.8–94.8 %. Based on the sequence comparison data, strain AK40T was positioned distinctly outside the group formed by the genera Phaeochromatium, Marichromatium, Halochromatium, Thiohalocapsa, Rhabdochromatium and Thiorhodovibrio. Distinct morphological, physiological and genotypic differences from previously described taxa supported the classification of this isolate as a representative of a novel species in a new genus, for which the name Phaeobacterium nitratireducens gen. nov., sp. nov. is proposed. The type strain of Phaeobacterium nitratireducens is AK40T ( = JCM 19219T = MTCC 11824T).

A novel Gram-negative, rod-shaped, non-motile, non-sporulating bacterium, designated strain K1T, was isolated from an estuarine water sample collected from Kochi, Kerala, India. Colonies on marine agar were circular, 2.0–2.5 mm in diameter, shiny, yellow, translucent and convex with entire margins. Strain K1T was negative for ornithine decarboxylase, lysine decarboxylase, nitrate reduction and H2S production. The fatty acids were dominated by iso-branched components with a high abundance of iso-C15 : 0, iso-C15 : 1 G and iso-C17 : 0 3-OH; MK-6 (64 %) and MK-7 (34 %) were found as major respiratory quinones; and phosphatidylethanolamine, two unidentified aminolipids, four unidentified phospholipids and two unidentified lipids were major polar lipids. The DNA G+C content of strain K1T was 46.1 mol%. 16S rRNA gene sequence analysis indicated that strain K1T was related most closely to the type strain of Zhouia amylolytica (pairwise sequence similarity of 93.0 %). Phylogenetic analysis showed that strain K1T formed a distinct branch within the family Flavobacteriaceae and clustered with the clade comprising species of the genera Zhouia , Coenonia and Capnocytophaga , being phylogenetically most closely related to the type strain of Zhouia amylolytica at a distance of 9.2 % (90.8 % similarity). Other species of the genera within the same clade were related to strain K1T at distances of 15.0–23.1 %. Based on phenotypic and chemotaxonomic characteristics and on phylogenetic inference, strain K1T is considered to represent a novel species of a new genus in the family Flavobacteriaceae , for which the name Imtechella halotolerans gen. nov., sp. nov. is proposed. The type strain of Imtechella halotolerans is K1T ( = MTCC 11055T = JCM 17677T).

A Gram-reaction-negative, chemo-organotrophic, non-motile, non-spore-forming, rod-shaped bacterium (strain Gsoil 080T) was isolated from soil collected in a ginseng field in Pocheon Province, South Korea, and was investigated by using a polyphasic taxonomic approach. Comparative 16S rRNA gene sequence analysis showed that strain Gsoil 080T was related most closely to Inquilinus limosus strains AU0476T and AU1979 (98.9 % similarity to both). Strain Gsoil 080T shared ≤91.3 % 16S rRNA gene sequence similarity with the type strains of other recognized species examined. The genus Inquilinus belongs to the family Rhodospirillaceae in the order Rhodospirillales, class Alphaproteobacteria. The predominant ubiquinone was Q-10 and the major fatty acids were summed feature 7 (C18 : 1 ω9c/ω12t/ω7c) and C19 : 0 cyclo ω8c. The G+C content of the genomic DNA of strain Gsoil 080T was 69.9 mol%. The level of DNA–DNA relatedness between strain Gsoil 080T and I. limosus LMG 20952T was 12 %. The results of genotypic analyses in combination with chemotaxonomic and physiological data demonstrated that strain Gsoil 080T represents a novel species of the genus Inquilinus, for which the name Inquilinus ginsengisoli sp. nov. is proposed.

Two bacterial strains (SC-089T and SC-092T) isolated from sewage sludge compost were characterized by using a polyphasic approach. The isolates were Gram-negative short rods, catalase- and oxidase-positive, and showed good growth at 30 °C, at pH 7 and with 1 % (w/v) NaCl. Ubiquinone 8 was the major respiratory quinone, and phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol were amongst the major polar lipids. On the basis of 16S rRNA gene sequence analysis, the strains were observed to be members of the family Alcaligenaceae, but could not be identified as members of any validly described genus. The low levels of 16S rRNA gene sequence similarity to other recognized taxa, together with comparative analysis of phenotypic traits and chemotaxonomic markers, supported the proposal of a new genus within the family Alcaligenaceae, for which the name Candidimonas gen. nov. is proposed. Strains SC-089T and SC-092T, which shared 99.1 % 16S rRNA gene sequence similarity, could be differentiated at the phenotypic level, and DNA–DNA hybridization results supported their identification as representing distinct species. The names proposed for these novel species are Candidimonas nitroreducens sp. nov. (type strain, SC-089T = LMG 24812T = CCUG 55806T) and Candidimonas humi sp. nov. (type strain, SC-092T = LMG 24813T = CCUG 55807T).

A Gram-negative, non-motile, aerobic bacterial strain, designated MJ20T, was isolated from farm soil near Daejeon (South Korea) and was characterized taxonomically by using a polyphasic approach. Comparative 16S rRNA gene sequence analysis showed that strain MJ20T belongs to the family Cytophagaceae, class Sphingobacteria, and was related most closely to Dyadobacter fermentans DSM 18053T (98.9 % sequence similarity), Dyadobacter beijingensis JCM 14200T (98.0 %) and Dyadobacter ginsengisoli KCTC 12589T (96.4 %). The G+C content of the genomic DNA of strain MJ20T was 48.5 mol%. The detection of MK-7 as the predominant menaquinone and a fatty acid profile with summed feature 4 (C16 : 1 ω7c and/or iso-C15 : 0 2-OH), iso-C15 : 0, C16 : 0 and C16 : 1 ω5c as major components supported the affiliation of strain MJ20T to the genus Dyadobacter. The new isolate exhibited relatively low levels of DNA–DNA relatedness with respect to D. fermentans DSM 18053T (mean±sd of three determinations, 47±7 %) and D. beijingensis JCM 14200T (38±8 %). On the basis of its phenotypic and genotypic properties together with phylogenetic distinctiveness, strain MJ20T (=KCTC 22481T =JCM 16232T) should be classified in the genus Dyadobacter as the type strain of a novel species, for which the name Dyadobacter soli sp. nov. is proposed.
