Taxonomic studies were performed on an agarase-producing strain, designated WV33T, isolated from faeces of Antarctic penguins. Cells of strain WV33T were Gram-staining-negative, strictly aerobic, orange and rod-shaped. Strain WV33T displayed agarase activity and was able to utilize galactose as a sole carbon source. 16S rRNA gene sequence analysis revealed that strain WV33T was closely related to Flavobacterium algicola TC2T (98.0 % similarity), F. frigidarium ATCC 700810T (96.9 %) and F. frigoris LMG 21922T (96.1 %). The predominant cellular fatty acids were iso-C15 : 1 G, iso-C15 : 0, C15 : 0, C16 : 0 and summed feature 3 (comprising iso-C15 : 0 2-OH and/or C16 : 1ω7c). Menaquinone 6 (MK-6) was the sole quinone identified, and the major pigment was zeaxanthin. The major polar lipid was phosphatidylethanolamine. DNA–DNA relatedness of strain WV33T with respect to its closest phylogenetic neighbours was 25 % for F. algicola NBRC 102673T, 23 % for F. frigidarium DSM 17623T and 21 % for F. frigoris DSM 15719T. The DNA G+C content of strain WV33T was 37±0.6 mol%. Based on the phenotypic, chemotaxonomic and phylogenetic data, strain WV33T is concluded to represent a novel species of the genus Flavobacterium , for which the name Flavobacterium faecale sp. nov. is proposed. The type strain is WV33T ( = KCTC 32457T = CECT 8384T).

A novel Gram-staining-negative bacterial strain, designated XH4T, was isolated from soil of a Populus euphratica forest in the Hotan River valley, Xinjiang Uyghur autonomous region, PR China. The cells were strictly aerobic, non-motile, short rods. The isolate grew optimally at 37 °C and at pH 7.0–8.0. Based on 16S rRNA gene sequence analysis, strain XH4T belonged to the genus Sphingobacterium and was closely related to Sphingobacterium mizutaii ATCC 33299T (96.1 % sequence similarity). The DNA G+C content was 41.2 mol%. The major polar lipid of strain XH4T was phosphatidylethanolamine, and several unidentified polar lipids were also present. Strain XH4T showed the typical chemotaxonomic features of the genus Sphingobacterium , with the presence of ceramide phosphorylethanolamine 2 (CerPE-2) as the major ceramide.

Two Gram-stain-negative, yellow-pigmented and strictly aerobic bacteria, designated strains SE-s27T and SE-s28T, were isolated from forest soil. Both strains were non-motile rods that were catalase-positive and oxidase-negative and grew optimally at 25–30 °C, pH 8.0 and with 0 % (w/v) NaCl. Strain SE-s28T produced flexirubin-type pigments, but strain SE-s27T did not produce them. Both strains contained menaquinone-6 as the sole respiratory quinone and phosphatidylethanolamine as a major polar lipid. As the major cellular fatty acids (>10 %), SE-s27T contained iso-C15 : 1 and iso-C15 : 1G, whereas SE-s28T contained iso-C15 : 0 and summed feature 3 comprising C16 : 1ω7c and/or C16 : 1ω6c and/or iso-C15 : 0 2-OH. The DNA G+C contents of strains SE-s27T and SE-s28T were 33.1 and 44.3 mol%, respectively. The results of phylogenetic analysis based on 16S rRNA gene sequences revealed that SE-s27T and SE-s28T formed respective distinct phylogenetic lineages within the genus Flavobacterium . Strains SE-s27T and SE-s28T were most closely related to Flavobacterium macrobrachii an-8T and Flavobacterium piscinae ICH-30T with 98.0 and 94.5 % 16S rRNA gene sequence similarities, respectively. In conclusion, strains SE-s27T and SE-s28T represent novel species of the genus Flavobacterium , for which the names Flavobacterium solisilvae sp. nov. and Flavobacterium silvaticum sp. nov. are proposed. The type strains of F. solisilvae and F. silvaticum are SE-s27T (=KACC 18802T=JCM 31544T) and SE-s28T (=KACC 18803T=JCM 31545T), respectively.

A novel Gram-staining-positive, rod-shaped, motile, strictly aerobic, endospore-forming bacterium, designated WCC 4585T, was isolated from a pharmaceutical production line. The organism grew optimally at 30 °C, at pH 8 and in the presence of 0.5 % (w/v) NaCl. Oval endospores were formed subterminally and terminally in swollen sporangia. The cell-wall diamino acid was meso-diaminopimelic acid (type A1γ) and the genomic DNA G+C content was 38.7 mol%. The major menaquinone was MK-7. The cellular fatty acid profile contained major amounts of iso-C15 : 0, anteiso-C15 : 0 and anteiso-C17 : 0, and the cellular phospholipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and aminophospholipid. The isolate was most closely related to Bacillus oceanisediminis H2T, Bacillus infantis SMC 4352-1T, Bacillus firmus NCIMB 9366T, Bacillus circulans ATCC 4513T and Bacillus horneckiae DSM 23495T with which it shared less than 98.0 % 16S rRNA gene sequence similarity. DNA–DNA relatedness values between strain WCC 4585T and five type strains of related species were ≤27 % and sequence similarity values based on groEL sequences were ≤88.7 %. On the basis of the characteristics presented, strain WCC 4585T is proposed to represent a novel species, Bacillus gottheilii sp. nov.

A strictly aerobic, Gram-negative, yellow-pigmented, non-spore-forming rod, designated 15C3T, was isolated from aerobic leaf-and-branch compost at EXPO Park in Osaka, Japan. Growth was observed at 9–33 °C (optimum 25 °C) and pH 5.6–7.9 (optimum pH 6.1–7.0). No growth occurred with >2 % (w/v) NaCl. Strain 15C3T reduced nitrate to nitrogen and showed catalase activity but not oxidase activity. The predominant fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH and summed feature 3 (comprising C16 : 1ω7c and/or iso-C15 : 0 2-OH). The isolate contained phosphatidylethanolamine as the major polar lipid and menaquinone-6 as the major respiratory quinone. The G+C content of the genomic DNA of strain 15C3T was 33.6 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain 15C3T belonged to the genus Flavobacterium and was most closely related to Flavobacterium hercynium WB 4.2-33T (96.9 % sequence similarity). On the basis of phenotypic and phylogenetic distinctiveness, strain 15C3T is considered to represent a novel species in the genus Flavobacterium , for which the name Flavobacterium compostarboris sp. nov. is proposed. The type strain is 15C3T ( = KACC 14224T  = JCM 16527T). Emended descriptions of F. hercynium , Flavobacterium resistens and Flavobacterium johnsoniae are also given.

A light-yellow-coloured bacterium, designated strain PTJT-5T, was isolated from the stem of Smilacina japonica A. Gray collected from Taibai Mountain in Shaanxi Province, north-west China, and was subjected to a taxonomic study by using a polyphasic approach. The novel isolate grew optimally at 25–28 °C and pH 6.0–7.0. Flexirubin-type pigments were produced. Cells were Gram-reaction-negative, strictly aerobic, rod-shaped and non-motile.

The major cellular fatty acids were iso-C15 : 0, iso-C15 : 1 G, iso-C17 : 0 and iso-C17 : 0 3-OH. The only polyamine was homospermidine and the major polar lipid was phosphatidylethanolamine. The only respiratory quinone was MK-7 and the DNA G+C content was 40.3 mol%. Based on the phenotypic, phylogenetic and genotypic data, strain PTJT-5T is considered to represent a novel species of a new genus in the family Chitinophagaceae , for which the name Taibaiella smilacinae gen. nov., sp. nov. is proposed. The type strain of Taibaiella smilacinae is PTJT-5T ( = CCTCC AB 2013017T = KCTC 32316T). An emended description of Flavihumibacter petaseus is also proposed.

A novel strain, designated strain CU3-7T, was isolated from faeces of a two-week-old baby. The isolate was Gram-staining-positive, anaerobic and rod-shaped. Results from 16S rRNA gene sequence analysis revealed that strain CU3-7T was phylogenetically affiliated with members of the genus Bifidobacterium . Strain CU3-7T showed the highest level of sequence similarity with Bifidobacterium adolescentis KCTC 3216T (98.4 %), followed by Bifidobacterium ruminantium KCTC 3425T (97.9 %). Analysis of hsp60 sequences showed that strain CU3-7T was closely related to B. adolescentis KCTC 3216T (94.0 %) and B. ruminantium KCTC 3425T (92.5 %). The DNA–DNA hybridization values with the closely related strains were all below the cut-off value for species delineation, 17.0 % with B. ruminantium KCTC 3425T and 14.9 % with B. adolescentis KCTC 3216T. Fructose-6-phosphate phosphoketolase activity was detected. The predominant cellular fatty acids were C16 : 0 (27.7 %), C18 : 1ω9c (27.4 %) and C18 : 1ω9c dimethylacetate (15.5 %). The DNA G+C content was 58.6 mol%. On the basis of polyphasic taxonomy, strain CU3-7T should be classified as the type strain of a novel species within the genus Bifidobacterium , for which the name Bifidobacterium faecale sp. nov. is proposed ( = KACC 17904T = JCM 19861T).
