Three novel bacterial strains, designated Vu-144T, Vu-7 and Vu-35, were isolated on minimal medium from rhizosphere soil of field-grown cowpea and subjected to a taxonomic study using a polyphasic approach. Cells of the strains were Gram-stain-negative, non-motile, non-spore-forming, coccoid rods, and formed non-pigmented colonies. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain Vu-144T was affiliated with an uncultivated lineage of the phylum Bacteroidetes . Its closest phylogenetic neighbour was the recently described species Niastella populi , a member of the family Chitinophagaceae , with just 90.7 % sequence similarity to the type strain. The only isoprenoid quinone detected was menaquinone 7 (MK-7). The fatty acid profiles showed large amounts of iso-C15 : 0, iso-C17 : 0 3-OH and iso-C15 : 1 G and minor amounts of summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH), C16 : 0 and other fatty acids, allowing the differentiation of the strains from other genera. The G+C content of the genomic DNA of the three strains ranged from 43.1 to 44.3 mol%. In addition to phosphatidylethanolamine, the major polar lipids were three unidentified aminophospholipids (APL1–APL3), two unidentified phospholipids (PL1, PL2) and three unidentified lipids (UL1–UL3). Biochemical test patterns also differed from those of Niastella populi and members of other genera. All three isolates showed plant-growth-promoting properties, e.g. the ability to produce indole-3-acetic acid and NH3 and to solubilize phosphate, utilized 1-aminocyclopropane 1-carboxylate (ACC) as a sole source of nitrogen and possessed the ACC deaminase enzyme. The novel isolates readily colonized roots and stimulated growth of tomato and cowpea under glasshouse conditions. Inoculated plants showed a 45–60 % increase in dry matter weight with respect to uninoculated controls. On the basis of the evidence from our polyphasic study, isolate Vu-144T represents a novel genus and species in the family Chitinophagaceae , for which the name Arachidicoccus rhizosphaerae gen. nov., sp. nov. is proposed. The type strain of Arachidicoccus rhizosphaerae is Vu-144T ( = KCTC 22378T = NCIMB 14473T).

A novel non-motile, Gram-staining-negative, yellow-pigmented bacterium, designated AG13T, isolated from a rain water pond at a plant nursery in Spain and characterized as a plant-growth-promoting bacterium, was investigated to determine its taxonomic status. The isolate grew best over a temperature range of 15–40 °C, at pH 5.0–8.0 and with 0–4 % (w/v) NaCl. Chemotaxonomic and molecular characteristics of the isolate matched those described for members of the genus Chryseobacterium . The DNA G+C content of the novel strain was 37.2 mol%. The strain had a polyamine pattern with sym-homospermidine as the major compound and produced flexirubin-type pigments. MK-6 was the dominant menaquinone and the major cellular fatty acids were iso-C15 : 0, C17 : 1ω9c and iso-C17 : 0 3-OH. The main polar lipids were phosphatidylethanolamine, aminolipids and several unidentified lipids. The 16S rRNA gene showed 92.0–97.2 % sequence similarity with those of the members of the genus Chryseobacterium . Based on chemotaxonomic and phenotypic traits, and DNA–DNA hybridizations with the type strains of the most closely related species, the isolate is proposed to represent a novel species, Chryseobacterium hispalense, type strain AG13T ( = DSM 25574T = CCUG 63019T). Emended descriptions of the species Chryseobacterium defluvii , Chryseobacterium indologenes , Chryseobacterium wanjuense and Chryseobacterium gregarium are also provided.

Four novel strains isolated from the cloacal contents of snow finches (Montifringilla taczanowskii) were characterized as aerobic, Gram-stain-negative, slightly motile, and rod-shaped. Analysis of the 16S rRNA gene sequence revealed that strain CF-458T had the highest similarities of 96.9 and 96.4 % with Limnobaculum parvum HYN0051T and Pragia fontium DSM 5563T, while strain CF-1111T shared the highest similarities of 96.4 and 96.1 % with Pantoea rodasii LMG 26273T and Pectobacterium punjabense SS95T. Phylogenomic analysis showed the four isolates were separated into group Ⅰ (CF-458T and CF-917) and group Ⅱ (CF-1111T and CF-509), and clustered independently in the vicinity of the genera Limnobaculum and Pragia . Summed feature 3 (C16 : 1  ω7c and/or C16 : 1  ω6c, 23.9 and 17.2 %, respectively), C16 : 0 (21.8 and 22.1 %, respectively) and C14 : 0 (10.6 and 17.7 %, respectively) were the common major fatty acids, and summed feature 8 (C18 : 1  ω7c and/or C18 : 1  ω6c, 12.3 %) was also a major fatty acid for strain CF-458T while cyclo-C17 : 0 (13.1%) was for strain CF-1111T. Both had Q-8 as the sole quinone and contained phosphatidylethanolamine, phosphatidylglycerol, and diphosphatidylglycerol as the major polar lipids. The DNA G+C content of strains CF-458T and CF-1111T was 45.7 and 45.4 mol%, respectively. Based on taxonomic position in the phylogenomic tree and phenotypic properties, two novel species of a new genus within the family Budviciaceae are thus proposed, with the name Jinshanibacter gen. nov., zhutongyuii sp. nov. (type strain CF-458T=CGMCC 1.16483T=GDMCC 1.1586T=JCM 33489T) and Jinshanibacter xujianqingii sp. nov. (type strain CF-1111T=CGMCC 1.16786T=GDMCC 1.1587T=JCM 33490T), respectively.

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).

Three strains of an anaerobic, Gram-stain-positive coccobacillus were isolated from the intestines of mice. These strains shared 100 % similarity in their 16S rRNA gene sequences, but were distantly related to any described members of the family Lachnospiraceae (<94 %). The most closely related species with names that have standing in nomenclature were Robinsoniella peoriensis , Ruminococcus gnavus , Blautia producta and Clostridium xylanolyticum . Phylogenetic relationships based on 16S rRNA gene sequence analysis were confirmed by partial sequencing of hsp60 genes. The use of an in-house database search pipeline revealed that the new isolates are most prevalent in bovine gut samples when compared with human and mouse samples for Ruminococcus gnavus and B. producta . All three isolated strains shared similar cellular fatty acid patterns dominated by C16 : 0 methyl ester. Differences in the proportions of C12 : 0 methyl ester, C14 : 0 methyl ester and C18 : 1 cis-11 dimethyl acetal were observed when compared with phylogenetically neighbouring species. The major short-chain fatty acid produced by strain SRB-530-5-HT was acetic acid. This strain tested positive for utilization of d-fructose, d-galacturonic acid, d-malic acid, l-alanyl l-threonine and l-glutamic acid but was negative for utilization of amygdalin, arbutin, α-d-glucose, 3-methyl d-glucose and salicin, in contrast to the type strain of the closest related species Robinsoniella peoriensis . The isolates were not able to use mannitol for growth. Based on genotypic, phenotypic and chemotaxonomic characteristics, we propose to create the new genus and species Murimonas intestini gen. nov., sp. nov. to accommodate the three strains SRB-530-5-HT ( = DSM 26524T = CCUG 63391T) (the type strain of Murimonas intestini), SRB-509-4-S-H ( = DSM 27577 = CCUG 64595) and SRB-524-4-S-H ( = DSM 27578 = CCUG 64594).

During our previous studies we reclassified Clostridium coccoides and a number of misclassified ruminococci into a novel genus Blautia within the family Lachnospiraceae . However, the Rules of the Bacteriological Code currently require that the types of all species and subspecies with new names (including new combinations) be deposited in two different collections in two different countries. The type strain of Ruminococcus obeum was, at that period in time, only deposited in the American Type Culture Collection (ATCC) and a second independent deposit, as required by the Code, was not available. Consequently, the transfer of this species to the genus Blautia could not be made, because the resulting species name would not conform to the Rules governing the valid publication of species names and deposit of type material (Rules 27 and 30) and consequently would not be considered to be validly published. This resulted in a nomenclatural and taxonomic anomaly with R. obeum being phylogenetically placed among members of the genus Blautia with 16S rRNA gene sequence similarities of between 91.8 and 96.6 %. In order to rectify this unsatisfactory situation, through our discussions with the ATCC, the deposit of strain R. obeum ATCC 29174T to the DSMZ as strain number DSM 25238T was completed. Hence, the transfer of R. obeum to the genus Blautia as Blautia obeum comb. nov. is now proposed. The type strain is ATCC 29174T ( = DSM 25238T = KCTC 15206T).

A Gram-stain-positive, non-motile rod, designated strain SGM3-12T, was isolated from paddy soil in Suwon, Republic of Korea. 16S rRNA gene sequence analysis revealed that the strain represented a novel member of the family Microbacteriaceae . The nearest phylogenetic neighbour was Leifsonia kribbensis MSL-13T (97.4 % 16S rRNA gene sequence similarity). Strain SGM3-12T and Leifsonia kribbensis MSL-13T formed a distinct cluster within the family Microbacteriaceae . Strain SGM3-12T contained MK-12(H2) and MK-11(H2) as the predominant menaquinones with moderate amounts of MK-12 and MK-11; anteiso-C15 : 0 and iso-C16 : 0 as the major cellular fatty acids (>10 % of total); and diphosphatidylglycerol, phosphatidylglycerol and unidentified glycolipids as the polar lipids. The peptidoglycan type of the isolate was B1δ with l-Lys as the diagnostic cell-wall diamino acid. On the basis of these results, strain SGM3-12T represents a novel species within a new genus, for which the name Lysinimonas soli gen. nov., sp. nov. is proposed (the type strain of the type species is SGM3-12T = KACC 13362T = NBRC 107106T). It is also proposed that Leifsonia kribbensis be transferred to this genus as Lysinimonas kribbensis comb. nov. (the type strain is MSL-13T = DSM 19272T = JCM 16015T = KACC 21108T = KCTC 19267T).

A Gram-type positive, Gram-reaction variable, non-motile, psychrophilic actinobacterium, designated Cr8-25T, was isolated from alpine glacier cryoconite and was able to grow well over a temperature range of 1–15 °C. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain Cr8-25T belonged to the family Microbacteriaceae and showed highest 16S rRNA gene sequence similarity with Klugiella xanthotipulae 44C3T (97.0 %). However, strain Cr8-25T could be differentiated from the type strain of K. xanthotipulae on the level of genomospecies by a DNA–DNA relatedness value of only 37.2 %. Strain Cr8-25T contained a cell-wall peptidoglycan that was cross-linked according to the B-type, which is based on 2,4-diaminobutyric acid. The cell wall contained the sugars galactose, fucose and rhamnose. The predominant cellular fatty acids of strain Cr8-25T were C15 : 0 anteiso (64.6 %) and iso-C16 : 0 (22.5 %) and the major menaquinones were MK-11 and MK-10. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and unknown glycolipids. The G+C content of the genomic DNA was 58.8 mol%. On the basis of the phenotypic characteristics, phylogenetic and chemotaxonomic analyses and DNA–DNA relatedness data, strain Cr8-25T represents a novel species of a new genus in the family Microbacteriaceae , for which the name Alpinimonas psychrophila gen. nov., sp. nov. is proposed. The type strain is Cr8-25T ( = DSM 23737T = LMG 26215T).

Five strains of anaerobic, Gram-negative bacilli isolated from the human oral cavity were subjected to a comprehensive range of phenotypic and genotypic tests and were found to comprise a homogeneous group. Phylogenetic analysis of full-length 16S rRNA gene sequences showed that these strains represented a novel group within the family Prevotellaceae , and the most closely related species was Prevotella tannerae . P. tannerae and the novel taxon are deeply branched from the genus Prevotella , with sequence identities to the type strain of the type species of Prevotella , Prevotella melaninogenica , of 82.2 and 85.6 %, respectively. The novel genus Alloprevotella gen. nov. is proposed to accommodate the novel species Alloprevotella rava gen. nov., sp. nov. and the previously named Prevotella tannerae Moore et al. 1994 as Alloprevotella tannerae gen. nov., comb. nov. The type species is Alloprevotella tannerae. The type strain of Alloprevotella rava is 81/4-12T ( = DSM 22548T  = CCUG 58091T) and the type strain of Alloprevotella tannerae is ATCC 51259T  = CCUG 34292T  = CIP 104476T  = NCTC 13073T. Alloprevotella rava is weakly to moderately saccharolytic and produces moderate amounts of acetic acid and major amounts of succinic acid as end products of fermentation. Strains are sensitive to 20 % bile and hydrolyse gelatin. The principal cellular long-chain fatty acids are anteiso-C15 : 0, iso-C15 : 0, C16 : 0, iso-C17 : 0 and iso-C17 : 0 3-OH. The G+C content of the DNA of the type strain is 47 mol%.

Strains RU-16T, RU-28, RU-04T and PU-02T were isolated from the gut of the African mole cricket, Gryllotalpa africana. Phylogenetic analyses based on 16S rRNA gene sequences revealed that the strains belonged to the family Microbacteriaceae . All four strains were most closely related to Curtobacterium ginsengisoli DCY26T (below 97 % 16S rRNA gene sequence similarity). These isolates were Gram-stain-positive, motile (by gliding), rod-shaped and exhibited ivory-coloured colonies. Their chemotaxonomic properties included MK-11 as the major respiratory quinone, ornithine as the cell-wall diamino acid, acetyl as the acyl type of the peptidoglycan, cyclohexyl-C17 : 0 as the major fatty acid and phosphatidylglycerol and diphosphatidylglycerol as the major polar lipids. On the basis of phenotypic, chemotaxonomic and phylogenetic analyses, we propose a new genus in the family Microbacteriaceae , Gryllotalpicola gen. nov., with three novel species, Gryllotalpicola daejeonensis sp. nov. (type strain RU-04T  = KCTC 13809T  = JCM 17590T), Gryllotalpicola koreensis sp. nov. (type strain RU-16T  = KCTC 13810T  = JCM 17591T) and Gryllotalpicola kribbensis sp. nov. (type strain PU-02T  = KCTC 13808T  = JCM 17593T). Gryllotalpicola koreensis is the type species of the genus. Additionally, we propose that Curtobacterium ginsengisoli should be reclassified in the genus as Gryllotalpicola ginsengisoli comb. nov. (type strain DCY26T  = KCTC 13163T  = JCM 14773T).

A novel bacterial strain, YC7001T, was isolated from the rhizosphere soil of rice collected at Jinju, Korea, and was characterized using a polyphasic approach. Cells of strain YC7001T were Gram-negative-staining, yellow-pigmented, rod-shaped, aerobic, heterotrophic and non-motile. Strain YC7001T grew optimally at 25–30 °C, pH 5.0–8.0 and degraded gelatin, cellulose and chitin. Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain YC7001T belonged to the genus Chitinophaga in the family Chitinophagaceae . The most closely related species were Chitinophaga sancti NBRC 15057T (96.9 %), Chitinophaga ginsengisoli Gsoil 052T (95.9 %), Chitinophaga pinensis DSM 2588T (95.7 %), Chitinophaga filiformis IFO 15056T (95.7 %) and Chitinophaga niabensis JS13-10T (95.0 %). The DNA–DNA relatedness value of strain YC7001T with C. sancti NBRC 15057T was 15.2±0.6 %. Strain YC7001T contained MK-7 as the major menaquinone and homospermidine as the major polyamine. The major fatty acids of strain YC7001T were C15 : 0 iso, C16 : 1ω5c and C17 : 0 iso 3-OH. The polar lipids were phosphatidylethanolamine, unknown aminolipids and unknown lipids. The total genomic DNA G+C content was 41.3 mol%. On the basis of phenotypic, chemotaxonomic and phylogenetic analyses, strain YC7001T represents a novel species of the genus Chitinophaga , in the family Chitinophagaceae , for which the name Chitinophaga oryziterrae sp. nov. is proposed. The type strain is YC7001T ( = KACC 14533T = JCM 16595T).
