Harbour Seals

A polyphasic taxonomic study was performed on two previously unidentified Arcanobacterium -like Gram-positive strains isolated from harbour seals. Comparative 16S rRNA gene sequencing showed that both bacteria belonged to the genus Arcanobacterium and were most closely related to Arcanobacterium haemolyticum CIP 103370T (98.4 % 16S rRNA gene sequence similarity), A. canis P6775T (97.4 %), A. phocae DSM 10002T (97.4 %), A. pluranimalium M430/94/2T (95.7 %) and A. hippocoleae CCUG 44697T (95.5 %). The presence of the major menaquinone MK-9(H4) supported the affiliation of the isolates with the genus Arcanobacterium . The polar lipid profile consisted of major amounts of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside, an unidentified phospholipid and two unidentified glycolipids. The major fatty acids were C16 : 0, C18 : 0, C18 : 1ω9c and summed feature 5 (comprising C18 : 2ω6,9c and/or anteiso-C18 : 0). Physiological and biochemical tests clearly distinguished the isolates from other members of the genus Arcanobacterium . Based on the common origin and various physiological properties comparable to those of A. phocae , it is proposed that the isolates are classified as members of a novel species with the name Arcanobacterium phocisimile sp. nov. The type strain is 2698T ( = LMG 27073T  = CCM 8430T).

A Gram-negative, rod-shaped, non-spore-forming bacterium, designated SgZ-1T, was isolated from the anode biofilm of a microbial fuel cell. The strain had the ability to grow under anaerobic condition via the oxidation of various organic compounds coupled to the reduction of anthraquione-2,6-disulfonate (AQDS) to anthrahydroquinone-2,6-disulfonate (AHQDS). Growth occurred in TSB in the presence of 0–5.5 % (w/v) NaCl (optimum 0–1 %), at 10–45 °C (optimum 25–37 °C) and at pH 6.0–10.0 (optimum 8.0–8.5). Based on 16S rRNA gene sequence similarity, strain SgZ-1T belonged to the genus Thauera . The highest level of 16S rRNA gene sequences similarity (96.7 %) was found to be with Thauera aminoaromatica S2 T and Thauera selenatis AXT, and lower values were obtained when compared with other recognized Thauera species. Chemotaxonomic analysis revealed that strain SgZ-1T contained Q-8 as the predominant quinone, and putrescine and 2-hydroxyputrescine as the major polyamines. The major cellular fatty acids (>5 %) were C16 : 1ω6c and/or C16 : 1ω7c (44.6 %), C16 : 0 (18.8 %), and C18 : 1ω6c and/or C18 : 1ω7c (12.7 %). Based on its phenotypic and phylogenetic properties, chemotaxonomic analysis and the results of physiological and biochemical tests, strain SgZ-1T ( = KACC 16524T = CCTCC M 2011497T) was designated the type strain of a novel species of the genus Thauera , for which the name Thauera humireducens sp. nov. was proposed.

Emended Description

A Gram-positive, non-endospore-forming bacterium, designated strain SK 18T, was isolated from surface soil of a landfill site by dilution plating on trypticase soy broth agar. Preliminary characterization of strain SK 18T via biochemical tests, analysis of fatty acid methyl esters and partial 16S rRNA gene sequencing placed it within the genus Microbacterium . Analysis of the cell wall indicated that the peptidoglycan was of cross-linkage type B, containing the amino acids lysine and ornithine and with muramic acid in the N-glycolyl form. The polar lipids were phosphatidylglycerol, diphosphatidylglycerol, an unidentified phospholipid and an unidentified glycolipid. The major fatty acids of the cell membrane were anteiso-C17 : 0, anteiso-C15 : 0 and iso-C16 : 0. These data further strengthened placement of the strain within the genus Microbacterium . Strain SK 18T shared highest 16S rRNA gene sequence similarity (97.2 %) with Microbacterium ulmi DSM 16931T. Levels of similarity with the type strains of all other recognized Microbacterium species were less than 97.0 %. DNA–DNA hybridization experiments with strain SK 18T and its closest relative, M. ulmi DSM 16931T, revealed a low reassociation value of 39.0 % (σ = 3.8 %). Moreover, strain SK 18T showed a number of differences in phenotypic characteristics (colony colour, catalase activity, hydrolysis of polymers, acid production from sugars and oxidation of various substrates), and its DNA G+C content was also higher than that of M. ulmi DSM 16931T. These data indicated that strain SK 18T represents a novel species of the genus Microbacterium , for which the name Microbacterium immunditiarum sp. nov. is proposed. The type strain is SK 18T ( = MTCC 7185T = JCM 14034T). An emended description of the genus Microbacterium is also provided.

A Gram-stain-negative, non-motile and rod-shaped bacterium, designated strain 5.0403-2T, was isolated from a cave soil sample collected from Tiandong Cave, Guizhou Province, south-west PR China. Cells showed positive oxidase and catalase reactions. The predominant isoprenoid quinone was MK-7. The major fatty acids were identified as iso-C15 : 0, summed feature 3 (C16 : 1 ω7c and/or C16 : 1 ω6c), iso-C17 : 0 3OH and summed feature 9 (iso-C17 : 1 ω9c or C16 : 0 10-methyl). The cellular polar lipids contained phosphatidylethanolamine, one unidentified phospholipid, three unidentified phosphoglycolipids and four unidentified lipids. The genomic DNA G+C content was 36.0 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain 5.0403-2T should be assigned to the genus Sphingobacterium . Results of 16S rRNA gene sequence similarity analysis showed that strain 5.0403-2T was most similar to Sphingobacterium bovisgrunnientis KCTC 52685T (98.7 %), Sphingobacterium composti KCTC 12578T (98.0 %) and Sphingobacterium alimentarium DSM 22362T (97.3 %) and less than 95.0 % similar to other species of the genus Sphingobacterium . The average nucleotide identity values between strain 5.0403-2T and S. bovisgrunnientis KCTC 52685T, S. composti KCTC 12578T and S. alimentarium DSM 22362T were 94.2, 82.3 and 77.2 % respectively. The digitalDNA–DNA hybridization values between strain 5.0403-2T and S. bovisgrunnientis KCTC 52685T, S. composti KCTC 12578T and S. alimentarium DSM 22362T were 68.4, 25.6 and 20.7 %. These results indicated that the isolate represented a novel genomic species. The polyphasic taxonomic characteristics indicated that strain 5.0304-2T represents a novel species of the genus Sphingobacterium , for which the name Sphingobacterium cavernae sp. nov. (type strain 5.0403–2T=KCTC 62981T=CCTCC AB 2019257T) is proposed.

Biochemical and molecular genetic studies were performed on four unknown Gram-stain-positive, catalase-negative, coccus-shaped organisms isolated from tonsils (n = 3) and nasal samples (n = 1) of four wild rabbits. The micro-organism was identified as a streptococcal species based on its cellular morphological and biochemical tests. Comparative 16S rRNA gene sequencing confirmed its identification as a member of the genus Streptococcus , but the organism did not correspond to any recognized species of this genus. The closest phylogenetic relative of the unknown cocci from wild rabbits was Streptococcus acidominimus NCIMB 702025T (97.9 % 16S rRNA gene sequence similarity). rpoB and sodA sequence analysis of the novel isolate showed interspecies divergence of 16.2 % and 20.3 %, respectively, from the type strain of its closest 16S rRNA gene phylogenetic relative, S. acidominimus . The novel bacterial isolate could be distinguished from the type strain of S. acidominimus by several biochemical characteristics, such as the production of esterase C4, acid phosphatase and naphthol-AS-BI-phosphohydrolase and acidification of different sugars. Based on both phenotypic and phylogenetic findings, it is proposed that the unknown bacterium be classified as a novel species of the genus Streptococcus , Streptococcus cuniculi sp. nov. The type strain is NED12-00049-6BT ( = CECT 8498T = CCUG 65085T).

A novel salt-tolerant alpha-proteobacterium, designated SALINAS58T, was isolated from Santa Engracia hypersaline spring water in the Añana Salt Valley, Álava, Spain. The isolate was Gram-negative, aerobic, non-motile, catalase-positive, oxidase-negative, rod-shaped and formed orange colonies on marine agar. Optimal growth was observed at pH 6.0–6.5, at 30 °C and in the presence of 1% (w/v) NaCl. The main cellular fatty acids (>20%) were summed feature 8 (C18 : 1 ω7c and/or C18 : 1 ω6c) and summed feature 3 (C16 : 1 ω7c and/or C16 : 1 ω6c). The major respiratory quinone was ubiquinone Q-10 and the major polar lipids detected were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidilglycerol, four unidentified glycolipids and one unidentified phospholipid. Strain SALINAS58T had the highest 16S rRNA gene sequence similarity to Altererythrobacter marensis MSW-14T (96.6%), Altererythrobacter aquaemixtae JSSK-8T (96.5%) and Pontixanthobacter luteolus SW-109T (96.5%) followed by Altererythrobacter atlanticus 26DY36T (96.4%). Results of the phylogenetic analysis, based on 16S rRNA gene sequences, and phylogenetic approaches based on whole genome nucleotide differences, showed that strain SALINAS58T could be distinguished from recognized species of the genus Altererythrobacter . The genomic DNA G+C content was 61.4 mol%. Digital DNA–DNA hybridization, average nucleotide identity and average aminoacid identity values between the genome of strain SALINAS58T and A. marensis MSW-14T were 18.4, 73.1 and 68.1%, respectively. Based on data from this polyphasic characterization, strain SALINAS58T (=CECT 30029T=LMG 31726T) is considered to be classified as representing a novel species in the genus Altererythrobacter , for which the name Altererythrobacter muriae sp. nov. is proposed.

Strains LMG 27428T and LMG 27427 were isolated from the caecal content of a chicken and produced butyric, lactic and formic acids as major metabolic end products. The genomic DNA G+C contents of strains LMG 27428T and LMG 27427 were 40.4 and 38.8 mol%. On the basis of 16S rRNA gene sequence similarity, both strains were most closely related to the generically misclassified Streptococcus pleomorphus ATCC 29734T. Strain LMG 27428T could be distinguished from S. pleomorphus ATCC 29734T based on production of more lactic acid and less formic acid in M2GSC medium, a higher DNA G+C content and the absence of activities of acid phosphatase and leucine, arginine, leucyl glycine, pyroglutamic acid, glycine and histidine arylamidases, while strain LMG 27428 was biochemically indistinguishable from S. pleomorphus ATCC 29734T. The novel genus Faecalicoccus gen. nov. within the family Erysipelotrichaceae is proposed to accommodate strains LMG 27428T and LMG 27427. Strain LMG 27428T ( = DSM 26963T) is the type strain of Faecalicoccus acidiformans sp. nov., and strain LMG 27427 ( = DSM 26962) is a strain of Faecalicoccus pleomorphus comb. nov. (type strain LMG 17756T = ATCC 29734T = DSM 20574T). Furthermore, the nearest phylogenetic neighbours of the genus Faecalicoccus are the generically misclassified Eubacterium cylindroides DSM 3983T (94.4 % 16S rRNA gene sequence similarity to strain LMG 27428T) and Eubacterium biforme DSM 3989T (92.7 % 16S rRNA gene sequence similarity to strain LMG 27428T). We present genotypic and phenotypic data that allow the differentiation of each of these taxa and propose to reclassify these generically misnamed species of the genus Eubacterium formally as Faecalitalea cylindroides gen. nov., comb. nov. and Holdemanella biformis gen. nov., comb. nov., respectively. The type strain of Faecalitalea cylindroides is DSM 3983T = ATCC 27803T = JCM 10261T and that of Holdemanella biformis is DSM 3989T = ATCC 27806T = CCUG 28091T.

A Gram-stain-negative, non-motile, aerobic and pleomorphic bacterium, designated BS-W13T, was isolated from a tidal flat on the South Sea, South Korea, and its taxonomic position was investigated using a polyphasic approach. Strain BS-W13T grew optimally at 25 °C, at pH 7.0–8.0 and in the presence of 1.0–2.0 % (w/v) NaCl. Neighbour-joining and maximum-parsimony phylogenetic trees based on 16S rRNA gene sequences showed that strain BS-W13T clustered with the type strain of Seohaeicola saemankumensis , showing the highest sequence similarity (95.96 %) to this strain. Strain BS-W13T exhibited 16S rRNA gene sequence similarity values of 95.95, 95.91, 95.72 and 95.68 % to the type strains of Sulfitobacter donghicola , Sulfitobacter porphyrae , Sulfitobacter mediterraneus and Roseobacter litoralis , respectively. Strain BS-W13T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c as the major fatty acid. The polar lipid profile of strain BS-W13T, containing phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, one unidentified aminolipid and one unidentified lipid as major components, was distinguishable from those of some phylogenetically related taxa. The DNA G+C content of strain BS-W13T was 58.1 mol%. The phylogenetic data and differential chemotaxonomic and other phenotypic properties revealed that strain BS-W13T constitutes a novel genus and species within family Rhodobacteraceae of the class Alphaproteobacteria , for which the name Pseudoseohaeicola caenipelagi gen. nov., sp. nov. is proposed. The type strain is BS-W13T ( = KCTC 42349T = CECT 8724T).

A Gram-stain-negative, aerobic, motile, rod-shaped bacterium, strain SC13E-S71T, was isolated from tuff, volcanic rock, where the Roman catacombs of Saint Callixtus in Rome, Italy, was excavated. Analysis of 16S rRNA gene sequences revealed that strain SC13E-S71T belongs to the genus Sphingopyxis , and that it shows the greatest sequence similarity with Sphingopyxis chilensis DSM 14889T (98.72 %), Sphingopyxis taejonensis DSM 15583T (98.65 %), Sphingopyxis ginsengisoli LMG 23390T (98.16 %), Sphingopyxis panaciterrae KCTC 12580T (98.09 %), Sphingopyxis alaskensis DSM 13593T (98.09 %), Sphingopyxis witflariensis DSM 14551T (98.09 %), Sphingopyxis bauzanensis DSM 22271T (98.02 %), Sphingopyxis granuli KCTC 12209T (97.73 %), Sphingopyxis macrogoltabida KACC 10927T (97.49 %), Sphingopyxis ummariensis DSM 24316T (97.37 %) and Sphingopyxis panaciterrulae KCTC 22112T (97.09 %). The predominant fatty acids were C18 : 1ω7c, summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1ω7c), C14 : 0 2-OH and C16 : 0. The predominant menaquinone was MK-10. The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine and sphingoglycolipid. These chemotaxonomic data are common to members of the genus Sphingopyxis . However, a polyphasic approach using physiological tests, DNA base ratios, DNA–DNA hybridization and 16S rRNA gene sequence comparisons showed that the isolate SC13E-S71T belongs to a novel species within the genus Sphingopyxis , for which the name Sphingopyxis italica sp. nov. is proposed. The type strain is SC13E-S71T ( = DSM 25229T = CECT 8016T).
