Four Gram-positive, catalase-positive, short rod- or coccoid-shaped bacterial strains, R27T, R44, R45 and R47, were isolated from an enrichment culture with diesel oil-degradation activity and their taxonomic positions were investigated using a polyphasic approach. Phenotypic, phylogenetic and genetic similarities indicated that strains R27T, R44, R45 and R47 belong to the same species. Phylogenetic analysis based on 16S rRNA gene sequences showed that the four strains form a distinct evolutionary lineage within the family Propionibacteriaceae. The novel four strains had cell-wall peptidoglycan based on ll-diaminopimelic acid, MK-9(H4) as the predominant menaquinone and anteiso-C15 : 0 as the major cellular fatty acid. The DNA G+C contents were 68.8–69.2 mol%. These chemotaxonomic properties, together with phylogenetic distinctiveness, distinguish the four novel strains from recognized members of the family Propionibacteriaceae. On the basis of phenotypic, chemotaxonomic, phylogenetic and genetic data, strains R27T, R44, R45 and R47 are classified as representatives of a new genus and novel species, Aestuariimicrobium kwangyangense gen. nov., sp. nov., within the family Propionibacteriaceae. The type strain of Aestuariimicrobium kwangyangense sp. nov. is R27T (=KCTC 19182T=JCM 14204T).

Two Gram-positive, catalase-positive, irregular short rod- or coccoid-shaped bacterial strains, N113T and R33, were isolated from an enrichment culture with diesel oil-degradation activity and their taxonomic positions were investigated using a polyphasic approach. Phenotypic, phylogenetic and genetic similarities indicated that strains N113T and R33 were representatives of the same species. Phylogenetic analysis based on 16S rRNA gene sequences showed that strains N113T and R33 form a lineage independent from those of members of the family Intrasporangiaceae. The novel isolates had cell-wall peptidoglycan based on meso-diaminopimelic acid, MK-8(H4) as the predominant menaquinone and 10-methyl-C18 : 0, iso-C16 : 0, C18 : 1 ω9c, C16 : 0 and C18 : 0 as the major cellular fatty acids. The DNA G+C contents were 69.6–69.9 mol%. These chemotaxonomic properties, together with phylogenetic distinctiveness, distinguish the two novel strains from recognized members of the family Intrasporangiaceae. On the basis of phenotypic, phylogenetic and genetic data, strains N113T (=KCTC 19143T=JCM 13585T) and R33 are classified as representatives of a novel genus and species, Kribbia dieselivorans gen. nov., sp. nov., within the family Intrasporangiaceae.

Eight facultatively anaerobic rod-shaped bacteria were isolated from raw milk and two other dairy products. Results of phylogenetic analyses based on 16S rRNA gene sequences showed that the isolates are placed in a distinct lineage within the family Propionibacteriaceae with Propioniciclava sinopodophylli and Propioniciclava tarda as the closest relatives (94.6 and 93.5 % similarity, respectively). The cell-wall peptidoglycan contained meso-diaminopimelic acid, alanine and glutamic acid and was of the A1γ type (meso-DAP-direct). The major cellular fatty acid was anteiso-C15 : 0 and the major polar lipids were diphosphatidylglycerol, phosphatidyglycerol and three unidentified glycolipids. The quinone system contained predominantly menaquinone MK-9(H4). The G+C content of the genomic DNA of strain VG341T was 67.7 mol%. The whole-cell sugar pattern contained ribose, rhamnose, arabinose and galactose. On the basis of phenotypic and genetic data, eight strains (VG341T, WS4684, WS4769, WS 4882, WS4883, WS4901, WS4902 and WS4904) are proposed to be classified as members of a novel species in a new genus of the family Propionibacteriaceae , for which the name Brevilactibacter flavus gen. nov., sp. nov. is proposed. The type strain is VG341T (=WS4900T=DSM 100885T=LMG 29089T) and seven additional strains are WS4684, WS4769, WS4882, WS4883, WS4901, WS4902 and WS4904. Furthermore, we propose the reclassification of P. sinopodophylli as Brevilactibacter sinopodophylli comb. nov.

A Gram-positive, rod-shaped, non-spore-forming and strictly aerobic bacterium (Gsoil 161T) was isolated from soil of a ginseng field in Pocheon Province, South Korea. The novel isolate was characterized using a polyphasic approach in order to determine its taxonomic position. On the basis of 16S rRNA gene sequence similarity, strain Gsoil 161T was shown to belong to the family Nocardioidaceae and was related to Aeromicrobium marinum (98.0 % similarity to the type strain), Aeromicrobium alkaliterrae (97.6 %), Aeromicrobium fastidiosum (97.0 %) and Aeromicrobium erythreum (96.7 %); the sequence similarity with other species within the family was less than 94.4 %. It was characterized chemotaxonomically as having ll-2,6-diaminopimelic acid in the cell-wall peptidoglycan, MK-9(H4) as the predominant menaquinone and C16 : 0, 10-methyl C18 : 0 (tuberculostearic acid), C16 : 0 2-OH, 10-methyl C17 : 0 and 10-methyl-C16 : 0 as the major fatty acids. The G+C content of the genomic DNA was 65.5 mol%. These chemotaxonomic properties and phenotypic characteristics support the affiliation of strain Gsoil 161T to the genus Aeromicrobium. Results of physiological and biochemical tests enabled strain Gsoil 161T to be differentiated genotypically and phenotypically from currently known Aeromicrobium species. Therefore, strain Gsoil 161T represents a novel species, for which the name Aeromicrobium panaciterrae sp. nov. is proposed. The type strain is strain Gsoil 161T (=KCTC 19131T=DSM 17939T=CCUG 52476T).

An obligately aerobic, spherical, non-motile, pale-yellow pigmented bacterium was isolated from a piece of leaf of seagrass, Enhalus acoroides (L.f.) Royle, grown in Okinawa, Japan and was subjected to a polyphasic taxonomic study. Phylogenetic analyses based on 16S rRNA gene sequences revealed that the novel isolate N5FB36-5T shared approximately 96–98 % sequence similarity with the species of the genus Pelagicoccus of the family Puniceicoccaceae within the phylum ‘Verrucomicrobia’. The DNA–DNA relatedness values of strain N5FB36-5T with Pelagicoccus mobilis 02PA-Ca-133T and Pelagicoccus albus YM14-201T were below 70 %, which is accepted as the phylogenetic definition of a novel species. β-Lactam antibiotic susceptibility test and amino acid analysis of the cell wall hydrolysates indicated the absence of muramic acid and diaminopimelic acid in the cell walls, which suggested that this strain lacks an ordinary Gram-negative type of peptidoglycan in the cell wall. The DNA G+C content of strain N5FB36-5T was 51.6 mol%; MK-7 was the major menaquinone; and the presence of C16 : 0, C16 : 1 ω7c and anteiso-C15 : 0 as the major cellular fatty acids supported the identification of the novel isolate as a member of the genus Pelagicoccus. On the basis of polyphasic taxonomic data, it was concluded that this strain should be classified as a novel species of the genus Pelagicoccus, for which the name Pelagicoccus croceus sp. nov. is proposed. The type strain is N5FB36-5T (=MBIC08282T=KCTC 12903T).

Distinct Taxon

Two actinomycete strains were isolated from soil surrounding mangrove roots. The isolates formed short spore chains with spores showing diverse shapes. The isolates contained glutamic acid, glycine, alanine and meso-diaminopimelic acid in the cell wall, 3-O-methylmannose, mannose, galactose and glucose as the whole-cell sugars and MK-10(H6), MK-10(H4), MK-9(H6) and MK-9(H4) as the predominant isoprenoid quinones. The isolates formed a distinct taxon in the phylogenetic tree of the Micromonosporaceae based on analysis of 16S rRNA gene sequences and showed chemical and phenotypic properties that were different from members of all of the other genera of this family. Based on these observations, it is proposed that the novel isolates belong to a new genus, Polymorphospora gen. nov. The type species of the genus is proposed as Polymorphospora rubra sp. nov., with strain TT 97-42T (=NBRC 101157T=DSM 44947T) as the type strain.

A Gram-reaction-positive, rod-shaped, non-motile, non-spore-forming bacterium (strain BX5-10T) was isolated from the soil of a ginseng field on Baekdu Mountain in Jilin district, China. The taxonomic position of this bacterium was determined in an investigation based on a polyphasic approach. On the basis of 16S rRNA gene sequence analysis, strain BX5-10T was shown to belong to the family Nocardioidaceae and to be most closely related to Nocardioides plantarum NCIMB 12834T (96.5 % sequence similarity), Nocardioides dokdonensis KCTC 19309T (96.2 %) and Nocardioides fonticola NAA-13T (95.1 %). Strain BX5-10T was characterized chemotaxonomically as having ll-2,6-diaminopimelic acid in its cell-wall peptidoglycan, MK-8(H4) as the predominant menaquinone and C18 : 1ω9c, C16 : 0 and C17 : 1ω8c as its major fatty acids. The G+C content of the genomic DNA was 70.3 mol%. The novel strain could be differentiated genotypically and phenotypically from all recognized species of the genus Nocardioides. Based on the results of the phylogenetic analyses and the genotypic and phenotypic data, a novel species, Nocardioides ginsengagri sp. nov., is proposed. The type strain is BX5-10T ( = KCTC 19467T = DSM 21362T).

Three bacterial strains, designated CCUG 51397T, CCUG 53736 and CCUG 53920, isolated from water samples taken at different locations in southern Sweden were studied to determine their taxonomic position using a polyphasic approach. Comparative analysis of 16S rRNA gene sequences showed that these bacteria had <93 % sequence similarity to all described species of the genera Sediminibacterium, Lacibacter, Flavihumibacter, Flavisolibacter, Niabella, Niastella, Segetibacter, Parasegetibacter, Terrimonas, Ferruginibacter, Filimonas and Chitinophaga. The three organisms grouped most closely with Sediminibacterium salmoneum NJ-44T but showed only 92.5 % sequence similarity to this strain, the only recognized species of this genus. The fatty acid profiles showed large amounts of iso-C15 : 0, iso-C17 : 0 3-OH and iso-C15 : 1 G with smaller amounts of iso-C15 : 0 3-OH, iso-C16 : 0 3-OH and other fatty acids, which differentiated the novel strains from related genera. Biochemical tests performed on strains CCUG 51397T, CCUG 53736 and CCUG 53920 also gave different results from those of Sediminibacterium salmoneum NJ-44T and other related genera. Based on this evidence, strains CCUG 51397T, CCUG 53736 and CCUG 53920 represent a novel species of a new genus, for which the name Hydrotalea flava gen. nov., sp. nov. is proposed. The type strain of Hydrotalea flava is CCUG 51397T (=CCM 7760T). A formal allocation of the genera Sediminibacterium, Lacibacter, Flavihumibacter, Flavisolibacter, Niabella, Niastella, Segetibacter, Parasegetibacter, Terrimonas, Ferruginibacter, Filimonas and Chitinophaga to the family Chitinophagaceae fam. nov. is also proposed.

The taxonomic position of three bacterial strains, Asr22-19T, NBRC 101035 and NBRC 101041, isolated from shellfish in Japan, was determined by using a polyphasic taxonomic approach. The strains were facultatively anaerobic, motile by gliding and Gram-staining-negative slender rods. Their major respiratory quinone was menaquinone-7 and their predominant cellular fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH, iso-C15 : 0 3-OH, C16 : 0 3-OH, and C16 : 0. The G+C content of the genomic DNA was 42.0–42.7 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that the strains clustered with the genus Persicobacter in the family ‘Flammeovirgaceae’. DNA–DNA relatedness values were higher than 68 % among strains Asr22-19T, NBRC 101035 and NBRC 101041, and were lower than 28 % between strain Asr22-19T and Persicobacter diffluens NBRC 15940T. The three novel strains could be differentiated from Persicobacter diffluens by several phenotypic characteristics. On the basis of these results, the novel species Persicobacter psychrovividus sp. nov. (type strain Asr22-19T=NBRC 101262T=CIP 109100T) is proposed and emended descriptions are given for the genus Persicobacter and for Persicobacter diffluens.

Two novel Gram-staining-positive, rod-shaped, endospore-forming and moderately thermophilic bacteria, designated strains DX-3T and GIESS002, were isolated from sludge composts from Guangdong Province, China. Analysis of 16S rRNA gene sequences revealed that the isolates were closely related to each other with extremely high similarity (99.6 %), and were members of the family Bacillaceae . However, these two isolates formed a novel phylogenetic branch within this family. Their closest relatives were the members of the genera Ornithinibacillus , Oceanobacillus and Virgibacillus . Cells of both strains were facultatively anaerobic and catalase- and oxidase-positive. The cell-wall peptidoglycan type was A1γ (meso-diaminopimelic acid direct). The predominant isoprenoid quinone was MK-7. The main polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. The major cellular fatty acid was iso-C15 : 0. The DNA G+C content was 43.2–43.7 mol%. The results of a polyphasic taxonomic study indicated that strains DX-3T and GIESS002 represent a novel species in a new genus in the family Bacillaceae , order Bacillales , for which the name Compostibacillus humi gen. nov., sp. nov. is proposed. The type strain is DX-3T ( = KCTC 33104T = CGMCC 1.12360T).

A novel Gram-stain-positive, non-spore-forming, pale yellow, irregular rod-shaped bacterium designated strain HWE2-01T was isolated from the surface-sterilized root of horseweed (Conyza canadensis). Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain HWE2-01T belongs to the family Microbacteriaceae and showed sequence similarity levels of 97.1–97.7 % with species of the genus Salinibacterium , 95.9–97.6 % with species of the genus Leifsonia and 97.1 % with Homoserinimonas aerilata . The highest sequence similarity (97.7 %) was with Salinibacterium xinjiangense 0543T. The genomic DNA G+C content of the novel strain was 68.1 mol%. The predominant cellular fatty acid of strain HWE2-01T was anteiso-C15 : 0, major menaquinones were MK-10, MK-9 and MK-11, and diagnostic polar lipids were diphosphatidylglycerol and phosphatidylglycerol. The peptidoglycan of the novel strain contained 2,4-diaminobutyric acid, alanine, glycine and glutamic acid. The cell-wall sugars of strain HWE2-01T were galactose, mannose and rhamnose. The murein was of the acetyl type. Based on the results of the phenotypic and phylogenetic analysis, strain HWE2-01T differed in some respects from other members of the family Microbacteriaceae . Therefore, strain HWE2-01T is proposed to represent a novel species of a new genus in the family Microbacteriaceae with the name Conyzicola lurida gen. nov., sp. nov. (type strain = HWE2-01T = KCTC 29231T = JCM 19257T).
