Sequence Similarities

A Gram-positive, aerobic, rod-shaped, motile, endospore-forming bacterium was isolated from pasteurized milk from Bavaria, Germany. 16S rRNA gene sequence similarities indicated that strain WSBC 24001T was most closely related to Virgibacillus species (95.3–96.1 %), Oceanobacillus species (95.6–95.7 %), Bacillus firmus IAM 12464T (95.5 %) and Bacillus niacini IFO 15566T (95.2 %). However, strain WSBC 24001T showed the highest level of sequence similarity to an unnamed strain, MB-9T (97.6 %), which was isolated from coastal surface sediments in California. Hence, this strain was included in our study. The genomic DNA G+C contents of strains WSBC 24001T and MB-9T were 36.4 mol and 40.8 mol%, respectively. The major respiratory quinone of both strains was menaquinone MK-7 and the peptidoglycan type was A4β (l-orn←d-Asp). The polar lipid profiles of these strains contained a predominance of diphosphatidylglycerol and moderate to minor amounts of phosphatidylglycerol, an unknown phospholipid and an unknown aminophospholipid. However, strain WSBC 24001T could be distinguished from strain MB-9T by the presence of an unknown lipid. The fatty acid profiles of the two strains comprised mainly iso- and anteiso-branched acids, but showed some significant quantitative differences in the amounts of certain acids. The DNA–DNA relatedness value (15.5 %) clearly demonstrated that strains WSBC 24001T and MB-9T are representatives of two different species. On the basis of their phylogenetic position and morphological, physiological and chemotaxonomic properties, a novel genus is proposed, Ornithinibacillus gen. nov., with two novel species, the type species Ornithinibacillus bavariensis sp. nov. (type strain WSBC 24001T=DSM 15681T=CCM 7096T) and Ornithinibacillus californiensis sp. nov. (type strain MB-9T=DSM 16628T=CCM 7237T).

Sequence Similarities

A yellow-pigmented, Gram-staining-negative, non-motile, strictly aerobic and rod-shaped bacterium, designated CS100T, was isolated from soil in Chungbuk, Korea. Phylogenetic analysis and comparative studies based on the 16S rRNA gene sequence showed that strain CS100T belonged to the genus Flavobacterium in the family Flavobacteriaceae. Strain CS100T showed the highest sequence similarities to Flavobacterium glaciei JCM 13953T (97.6 %) and Flavobacterium johnsoniae KACC 11410T (97.1 %). Sequence similarity to other members of the genus Flavobacterium was 91.5–97.0 %. Growth occurred at 4–30 °C, at pH 5.0–9.0 and in the presence of 0–2 % (w/v) NaCl. Flexirubin-type pigments were produced. Menaquinone-6 (MK-6) was the major respiratory quinone and the major fatty acids were iso-C15 : 0 (17.3 %), summed feature 3 (comprising iso-C15 : 0 2-OH and/or C16 : 1ω7c, 15.5 %) and C16 : 0 (11.8 %). The DNA G+C content was 36.4 mol%. Strain CS100T hydrolysed skimmed milk and gelatin, but not chitin or pectin, and showed oxidase and catalase activities. DNA–DNA relatedness was 3.0 % with F. glaciei JCM 13953T and 11.5 % with F. johnsoniae KACC 11410T. On the basis of the evidence from this study, strain CS100T represents a novel species of the genus Flavobacterium, for which the name Flavobacterium chungbukense sp. nov. is proposed. The type strain is CS100T ( = KACC 15048T = JCM 17386T).

A novel actinobacterium, designated strain C4-31T, was isolated from soil collected from a cave. Cells were aerobic, Gram-reaction-positive, oxidase-negative, catalase-positive and non-motile cocci. Comparison of 16S rRNA gene sequences showed that the organism occupied a distinct phylogenetic position within the suborder Frankineae, with sequence similarity values of less than 93.2 % to members of this suborder. The diagnostic diamino acid in the cell-wall peptidoglycan was meso-diaminopimelic acid. The major menaquinone was MK-9(H4). The polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannoside, an unknown aminophospholipid and an unknown phospholipid. The major fatty acids were iso-C16 : 0, C17 : 1ω6c and C16 : 0. The G+C content of the DNA was 62.8 mol%. On the basis of morphological and chemotaxonomic data as well as phylogenetic evidence, strain C4-31T ( = KCTC 39556T = DSM 100065T) is considered to represent the type strain of a novel species of a new genus in the suborder Frankineae, for which the name Antricoccus suffuscus gen. nov., sp. nov. is proposed.

A Gram-reaction-positive, rod-shaped, spore-forming bacterium, designated Gsoil 1105T, was isolated from soil of a ginseng field in Pocheon Province in South Korea and characterized in order to determine its taxonomic position. Comparative analysis of the 16S rRNA gene sequence showed that the isolate belongs to the order Bacillales, showing the highest level of sequence similarity with respect to Tumebacillus permanentifrigoris Eur1 9.5T (94.6 %). The phylogenetic distances from other described species with validly published names within the order Bacillales were greater than 9.0 %. Strain Gsoil 1105T had a genomic DNA G+C content of 55.6 mol% and menaquinone 7 (MK-7) as the major respiratory quinone. The major fatty acids were iso-C15 : 0 and anteiso-C15 : 0. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain Gsoil 1105T represents a novel species of the genus Tumebacillus, for which the name Tumebacillus ginsengisoli sp. nov. is proposed. The type strain is Gsoil 1105T ( = KCTC 13942T  = DSM 18389T).

Polyphasic Characterization

A novel isolate, CP153-2T, was obtained from topsoil biological crusts in the Colorado Plateau (USA). Colonies were black in colour due to melanin-like pigments when grown on oligotrophic medium, but not when grown on copiotrophic medium. Induction of melanogenesis was independent of growth phase or illumination conditions, including exposure to UVB and UVA radiation, but exposure to UVB could enhance total pigment production and growth under low nitrogen prevented its synthesis. This mode of regulation was previously unknown among melanin-producing bacteria. Polyphasic characterization of the strain revealed that cells were short, straight to curved or irregular rods that developed into pairs and formed multiseptate short filaments, with rare bud-like cells. Short rods were typically motile by means of flagella; multicellular structures tended to be sessile. Cells stained Gram-positive, grew at 4–30 °C and had a narrow range of pH tolerance (pH 5–9). The major fatty acids were iso-C15:0 iso-C16 : 0, anteiso-C15 : 0 and C18 : 1; MK-9(H4) was the major respiratory quinone. Its peptidoglycan contained meso-diaminopimelic acid. Based on 16S rRNA gene sequence similarity data, its closest relative (98.1 % similarity) was Modestobacter multiseptatus DSM 44406T, which is similar morphologically. Based on the above characteristics, strain CP153-2T was also assigned to the genus Modestobacter. However, CP153-2T had a relatedness of only 49.9 % in whole-genome reassociation comparisons with the type strain of M. multiseptatus and thus formally represents a novel species, for which the name Modestobacter versicolor sp. nov. is proposed. Additional evidence in support of a novel species comes from phenotypic and chemotaxonomic characteristics. Strain CP153-2T (=ATCC BAA-1040T =DSM 16678T) is the type strain of M. versicolor.

Cattle Farms

Two facultatively anaerobic bacterial strains, designated WR061T and WR054, were isolated from rice-straw residue in a methanogenic reactor treating waste from cattle farms in Japan. The two strains were phylogenetically positioned close to one another and had almost the same phenotypic properties. Cells were Gram-reaction-positive, non-motile, non-spore-forming, irregular rods. Cobalamin (vitamin B12) was required for growth. The strains utilized various carbohydrates, including hexoses and disaccharides, and produced acetate and propionate from these carbohydrates. Pentoses and polysaccharides were not utilized. They grew at 20–37 °C (optimum 35 °C) and pH 5.3–8.0 (optimum pH 6.8–7.5). Catalase and nitrate-reducing activities were detected. Aesculin was hydrolysed. The major cellular fatty acids were anteiso-C15 : 0 and C15 : 0 DMA, the major respiratory quinone was menaquinone MK-9(H4) and the genomic DNA G+C content was 69.3–69.5 mol%. The diagnostic diamino acid in the peptidoglycan was meso-diaminopimelic acid. Phylogenetic analysis based on 16S rRNA gene sequences placed the strains in the phylum Actinobacteria. Both strains were remotely related to the species in the family Propionibacteriaceae and Propionibacterium propionicum JCM 5830T was the most closely related type strain with a sequence similarity of 91.6 %. Based on phylogenetic, physiological and chemotaxonomic analyses, the two novel strains together represent a novel species of a new genus, for which the name Propioniciclava tarda gen. nov., sp. nov. is proposed. The type strain is WR061T ( = JCM 15804T  = DSM 22130T).

Major Respiratory Quinone

A novel Gram-negative, rod-shaped, motile bacterium, designated strain AK13T, was isolated from a sediment sample collected from mangrove of Namkhana, Sunderbans, West Bengal, India. Strain AK13T was positive for oxidase, DNase and lipase activities and negative for catalase, gelatinase, ornithine decarboxylase, lysine decarboxylase, nitrate reductase, aesculinase and urease activities. The fatty acids were dominated by iso-C11 : 0, iso-C11 : 0 3-OH, iso-C15 : 0, iso-C16 : 0, iso-C17 : 1ω9c and summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH). Strain AK13T contained Q-8 as the major respiratory quinone and diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylserine, two unidentified aminolipids, one unidentified glycolipid and one unidentified lipid as the polar lipids. The DNA G+C content of strain AK13T was 55.2 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the type strain of Silanimonas lenta , of the family Xanthomonadaceae (phylum Proteobacteria ), was the closest neighbour of strain AK13T, with 95.2 % sequence similarity. Other members of the family showed sequence similarities <94.4 %. Based on the phenotypic characteristics and phylogenetic inference, strain AK13T is proposed as a member of a novel species of the genus Silanimonas , Silanimonas mangrovi sp. nov.; the type strain is AK13T ( = MTCC 11082T  = DSM 24914T). An emended description of the genus Silanimonas is also provided.

A non-motile, pale-yellow bacterium, designated strain HMD1056T, was isolated from an artificial lake located within the campus of Hankuk University of Foreign Studies, Yongin, Korea. The major fatty acids were summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1ω7c; 49.1 %) and iso-C15 : 0 (22.4 %). The major respiratory quinone was MK-7. The DNA G+C content was 46.9 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain HMD1056T formed a lineage within the genus Mucilaginibacter and was closely related to the type strains of Mucilaginibacter ximonensis (95.4 % sequence similarity), Mucilaginibacter kameinonensis (94.5 %) and Mucilaginibacter paludis (93.4 %). On the basis of the evidence presented in this study, strain HMD1056T represents a novel species of the genus Mucilaginibacter, for which the name Mucilaginibacter myungsuensis sp. nov. is proposed. The type strain is HMD1056T ( = KCTC 22746T  = CECT 7550T).

A strictly aerobic, Gram-staining-negative, oxidase- and catalase-positive, non-motile, rod-shaped bacterium, designated strain 5416T-29T, was isolated from air and was characterized by using a polyphasic approach. Colonies were reddish pink and circular with entire margins. Flexirubin-type pigments were absent. The strain formed a distinct phylogenetic lineage within the family Cytophagaceae of the phylum Bacteroidetes. Strain 5416T-29T did not show more than 88 % 16S rRNA gene sequence similarity to the type strain of any recognized species. The major cellular fatty acids were C16 : 1 ω5c, iso-C17 : 0 3-OH and iso-C15 : 0. The polar lipids were phosphatidylethanolamine, one unknown amino lipid and several unknown polar lipids. Menaquinone-7 (MK-7) was the major respiratory quinone. The G+C content of the DNA of strain 5416T-29T was 45.5 mol%. Results of phenotypic and phylogenetic analyses clearly indicate that strain 5416T-29T represents a novel species of a new genus in the family Cytophagaceae, for which the name Rhodocytophaga aerolata gen. nov., sp. nov. is proposed. The type strain of Rhodocytophaga aerolata is 5416T-29T (=KACC 12507T =DSM 22190T).

A Gram-negative, moderately halophilic, non-motile, aerobic bacterium, designated strain YIM D10T, was isolated from a salt mine sediment sample from Yunnan, south-west China. The strain grew optimally in the presence of 3–8 % NaCl and at 28 °C and pH 7.5. The polar lipid profile of strain YIM D10T comprised diphosphatidylglycerol, an unknown phospholipid and two unknown aminolipids. The major cellular fatty acids were C18 : 1 ω7c (30.5 %), C19 : 0 cyclo ω8c (29.3 %) and C18 : 0 (13.2 %). The respiratory quinone was ubiquinone 10 (Q-10). The genomic DNA G+C content was 65.4 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain YIM D10T was closely related to Amorphus coralli RS.Sph.026T (96.8 % gene sequence similarity). Results confirmed the placement of isolate YIM D10T within the genus Amorphus. However, DNA–DNA hybridization between strain YIM D10T and the type strain of the only recognized species of the genus Amorphus, A. coralli RS.Sph.026T, was 16.7 %, showing clearly that the isolate constitutes a new genospecies. Strain YIM D10T could be clearly differentiated from A. coralli and other phylogenetic neighbours on the basis of some phenotypic, genotypic and chemotaxonomic features. Therefore, strain YIM D10T is considered to represent a novel species of the genus Amorphus, for which the name Amorphus orientalis sp. nov. is proposed; the type strain is YIM D10T (=DSM 21202T=CCTCC AA 208035T).

The taxonomic position of a novel bacterial strain, Ch06T, isolated from an upflow anaerobic sludge blanket reactor was determined. Strain Ch06T was Gram-negative, aerobic, motile and oxidase- and catalase-positive. A comparative 16S rRNA gene sequence analysis showed a clear affiliation of strain Ch06T to the Alphaproteobacteria and it was most closely related to Zoogloea ramigera ATCC 19623 and Mycoplana dimorpha IAM 13154T (97·9 and 96·3 % sequence similarity, respectively). The major respiratory quinone was Q-10 and the predominant fatty acids were C16 : 0, 3-OH C16 : 0, C18 : 0, C19 : 0 cyclo ω8c and summed feature 7 (C18 : 1 ω7c/ω9t/ω12t, C18 : 1 ω7c/ω9c/ω12t). On the basis of phenotypic, chemotaxonomic and phylogenetic characteristics, the novel isolate was assigned to a new genus, Shinella gen. nov., as Shinella granuli gen. nov., sp. nov. (type strain Ch06T=KCTC 12237T=JCM 13254T). It is proposed that Zoogloea ramigera ATCC 19623 is reclassified into the novel genus Shinella as Shinella zoogloeoides sp. nov. (type strain ATCC 19623T=IAM 12669T=I-16-MT).
