The 16S Rrna Gene

Three Gram-staining-negative, rod-shaped, non-spore-forming, non-motile, oxidase-positive, yellow pigmented and aerobic bacterial isolates designated 8_R23573, 9_R23581T and 10_R23577 were isolated from raw chicken at a broiler processing plant in Bloemfontein, South Africa. A polyphasic taxonomic approach was used to determine their exact taxonomic identities. Phylogenetic analysis of the 16S rRNA gene sequences showed that the three strains belonged to the genus Chryseobacterium , exhibiting the highest similarities to Chryseobacterium shigense DSM 17126T (98.6–99.2 %) and Chryseobacterium luteum DSM 18605T (98.3–98.7 %). The most abundant quinone was menaquinone MK-6 and the predominant cellular fatty acids were iso-15 : 0, iso-17 : 1ω9c, iso-17 : 0 3-OH and summed feature 3 (iso-16 : 1ω7c and/or iso-15 : 0 2-OH), which supported the affiliation of the strains to the genus Chryseobacterium . The DNA G+C contents of the strains were 36.9, 36.7 and 36.6 mol% respectively. The DNA–DNA hybridization results gave relatedness values ranging from 78.8 to 87.2 % among the three strains and 23.4 to 56.1 % to the two nearest phylogenetic neighbours C. shigense DSM 17126T and C. luteum LMG 23785T. On the basis of the data from this polyphasic study, the three strains are concluded to represent a novel species of the genus Chryseobacterium for which the name Chryseobacterium carnipullorum sp. nov. is proposed. The type strain is 9_R23581T ( = LMG 26732T = DSM 25581T).

A Gram-stain-negative, rod-shaped and non-endospore-forming bacterium, designated strain AG1-2T, was isolated from Takakia lepidozioides collected from the Gawalong glacier in Tibet, China and characterized using a polyphasic taxonomic approach. The predominant fatty acids of strain AG1-2T were iso-C15 : 0 (36.0 %), iso-C17 : 0 3-OH (20.2 %), summed feature 9 (iso-C17 : 1ω9c and/or C16 : 0 10-methyl, 16.4 %) and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c, 11.1 %). The major polar lipids were phosphatidylethanolamine, three unidentified aminolipids and two unidentified lipids. Strain AG1-2T contained MK-6 as the dominant menaquinone, and the genomic DNA G+C content was 37.3 mol%. The phylogenetic analysis based on the 16S rRNA gene sequences showed that strain AG1-2T was affiliated to species of the genus Chryseobacterium , and its closest related species were Chryseobacterium taiwanense Soil-3-27T, Chryseobacterium hispalense AG13T, Chryseobacterium camelliae THG C4-1T and Chryseobacterium taeanense PHA3-4T with a sequence similarity of 98.0, 97.8, 97.3 and 97.1 %, respectively. However, the DNA–DNA relatedness values between these strains and strain AG1-2T were 29, 21, 21 and 45 %, respectively. Based on phylogenetic inference and phenotypic data, strain AG1-2T is considered to represent a novel species of the genus Chryseobacterium , for which the name Chryseobacterium takakiae sp. nov. is proposed. The type strain is AG1-2T ( = CGMCC 1.12488T = DSM 26898T).

The taxonomic status of a bacterium, strain DC-8T, isolated from activated sludge, was determined using a polyphasic taxonomic approach. The cells of strain DC-8T were Gram-negative, non-motile, non-spore-forming and rod-shaped. The isolate grew at temperature range of 10–40 °C (optimum 30–35 °C), pH range of 5.0–10.0 (optimum 6.5–8.0) and NaCl concentrations of 0–5 % (optimum 0–1 %). The predominant menaquinone of strain DC-8T was MK-7 and major fatty acids were summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c; 39.7 %), iso-C15 : 0 (33.7 %) and C16 : 0 (5.2 %). The DNA G+C content was 39.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequence comparison revealed that strain DC-8T was a member of the genus Sphingobacterium . Strain DC-8T shared the highest similarity with Sphingobacterium siyangense SY1T (98.4 %), Sphingobacterium multivorum IAM 14316T (98.3 %), Sphingobacterium canadense CR11T (98.0 %) and Sphingobacterium detergens 6.2ST (97.9 %) and shared less than 97 % similarity with other members of the genus Sphingobacterium . DNA–DNA hybridization experiments showed that the DNA–DNA relatedness values between strain DC-8T and its closest phylogenetic neighbours were below 70 %. Based on the phylogenetic analysis, DNA–DNA hybridization, whole-cell fatty acid composition as well as biochemical characteristics, strain DC-8T was clearly distinguished from all recognized species of the genus Sphingobacterium and should be classified as a representative of a novel species of the genus Sphingobacterium , for which the name Sphingobacterium caeni sp. nov. is proposed. The type strain is DC-8T ( = CCTCC AB 2012020T = KACC 16850T).

A Gram-staining-positive, spore-forming, obligately anaerobic, acetogenic bacterium, designated LAM1030T, was isolated from methanogenic consortia enriched from biogas slurry collected from the large-scale anaerobic digester of Modern Farming Corporation in Hebei Province, China. Cells of strain LAM1030T were motile, straight or spiral-rod-shaped. Strain LAM1030T could utilize glucose, fructose, maltose, galactose, lactose, sucrose, cellobiose, mannitol, pyruvate, succinic acid and tryptophan as the sole carbon source. Acetic acid, isovaleric acid and butanoic acid were the main products of glucose fermentation. Sodium sulfite was used as an electron acceptor. Growth of strain LAM1030T was completely inhibited by the addition of ampicillin, tetracycline, gentamicin or erythromycin at a concentration of 20 µg ml−1. The main polar lipids of strain LAM1030T were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, 11 unknown glycolipids and two unknown phospholipids. No respiratory quinone was detected. The major fatty acids of strain LAM1030T were C16 : 0 (21.1 %), C14 : 0 (10.3 %), summed feature 9 (including C16:0 10-methyl and/or iso-C17:1 ω9c) (11.3% ), summed feature 3 (including C16:1 ω7c and/or C16:1 ω6c) (10.6% ) and iso-C15 : 0 (6.6 %). Analysis of the 16S rRNA gene sequence indicated that strain LAM1030T belonged to the genus Clostridium and was most closely related to Clostridium subterminale DSM 6970T, Clostridium thiosulfatireducens DSM 13105T and Clostridium sulfidigenes DSM 18982T, with 97.0, 96.9 and 96.8 % similarity, respectively. The G+C content of the genomic DNA of strain LAM1030T was 31.2±0.3 mol%. On the basis of its phenotypic, phylogenetic and chemotaxonomic characterization, strain LAM1030T is suggested to represent a novel species of the genus Clostridium , for which the name Clostridium huakuii sp. nov. is proposed. The type strain is LAM1030T ( = ACCC 00698T = JCM 19186T).

The 16S Rrna Gene

Phylogenetic analysis of the 16S rRNA gene sequences of strains TE26T and K6 belonging to Wautersia numazuensis Kageyama et al. 2005 showed the strains to be deeply intermingled among the species of the genus Cupriavidus . The comparison showed that strain TE26T was closely related to the type strains of Cupriavidus pinatubonensis (99.1 % 16S rRNA gene sequence similarity), C. basilensis (98.7 %), C. necator (98.7 %) and C. gilardii (98.0 %). However, DNA–DNA hybridization experiments (less than 20 % relatedness) demonstrated that strain TE26T is different from these Cupriavidus species. A comparative phenotypic and chemotaxonomic analysis (based on fatty acid profiles) in combination with the 16S rRNA gene sequence phylogenetic analysis and the DNA–DNA hybridization results supported the incorporation of Wautersia numazuensis into the genus Cupriavidus as Cupriavidus numazuensis comb. nov.; the type strain is TE26T ( = LMG 26411T  = DSM 15562T  = CIP 108892T).

Four Gram-staining-positive, catalase-negative, coccoid isolates, designated NTUH_1465T, NTUH_2196, NTUH_4957 and NTUH_5572T, were isolated from human specimens. The four isolates displayed more than 99.6 % 16S rRNA gene sequence similarity with Gemella haemolysans ATCC 10379T, and 96.7 to 98.6 % similarity with Gemella sanguinis ATCC 700632T, Gemella morbillorum ATCC 27824T or Gemella cuniculi CCUG 42726T. However, phylogenetic analysis of concatenated sequences of three housekeeping genes, groEL, rpoB and recA, suggested that the four isolates were distinct from G. haemolysans ATCC 10379T and other species. Isolates NTUH_2196, NTUH_4957 and NTUH_5572T clustered together and formed a stable monophyletic clade. DNA–DNA hybridization values among strains NTUH_1465T and NTUH_5572T and their phylogenetically related neighbours were all lower than 49 %. The four isolates could be distinguished from G. haemolysans and other species by phenotypic characteristics. Based on the phylogenetic and phenotypic results, two novel species Gemella parahaemolysans sp. nov. (type strain NTUH_1465T = BCRC 80365T = JCM 18067T) and Gemella taiwanensis sp. nov. (type strain NTUH_5572T = BCRC 80366T = JCM 18066T) are proposed.

A novel actinobacterium, strain BC637T, was isolated from a biodeteriogenic biofilm sample collected in 2009 in the Saint Callixstus Roman catacomb. The strain was found to belong to the genus Kribbella by analysis of the 16S rRNA gene. Phylogenetic analysis using the 16S rRNA gene and the gyrB, rpoB, relA, recA and atpD concatenated gene sequences showed that strain BC637T was most closely related to the type strains of Kribbella lupini and Kribbella endophytica . DNA–DNA hybridization experiments confirmed that strain BC637T is a genomic species that is distinct from its closest phylogenetic relatives, K. endophytica DSM 23718T (63 % DNA relatedness) and K. lupini LU14T (63 % DNA relatedness). Physiological comparisons showed that strain BC637T is phenotypically distinct from the type strains of K. endophytica and K. lupini . Thus, strain BC637T represents the type strain of a novel species, for which the name Kribella italica sp. nov. is proposed ( = DSM 28967T = NRRL B-59155T).
