Emended Description

A Gram-staining-negative, catalase- and oxidase-positive, strictly aerobic, rod-shaped bacterial strain isolated from fresh water in Trabzon, Turkey and designated MK3T was characterized by phenotypic and molecular methods in order to determine its phylogenetic position. On the basis of 16S rRNA gene sequence similarity, strain MK3T was shown to belong to the genus Flavobacterium , being most closely related to Flavobacterium ceti CECT 7184T (93.6 %). Sequence similarity with other species of the genus Flavobacterium with validly published names was less than 91.6 %. Phenotypic and chemotaxonomic data supported the affiliation of strain MK3T to the genus Flavobacterium . The only menaquinone was MK-6; the major fatty acids were iso-C15 : 0 (45.2 %), summed feature 9 (C16 : 0 10-methyl and/or iso-C17 : 1ω9c; 20.4 %) and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c; 13.3 %) and the major polar lipids were phosphatidylethanolamine, one unidentified aminophospholipid and two unidentified phospholipids. The G+C content of the genomic DNA was 38.6 mol%. The results of physiological and biochemical tests allowed strain MK3T to be distinguished phenotypically from Flavobacterium ceti CECT 7184T. Strain MK3T, therefore, represents a novel species of the genus Flavobacterium , for which the name Flavobacterium anatoliense sp. nov. is proposed. The type strain is MK3T ( = LMG 26441T = NCCB 100384T). An emended description of Flavobacterium ceti is also proposed.

The Republic

A Gram-reaction-negative, strictly aerobic, non-motile, non-spore-forming and rod-shaped bacterial strain, designated THG-45T, was isolated from soil of a ginseng field of Pocheon province in the Republic of Korea and its taxonomic position was investigated by a polyphasic approach. Growth occurred at 4–30 °C, at pH 5.5–9.0 and with 0–2 % (w/v) NaCl on nutrient agar. On the basis of 16S rRNA gene sequence similarity, strain THG-45T was shown to belong to the genus Pedobacter and was related to Pedobacter borealis G-1T (98.8 %), P. alluvionis NWER-II11T (97.9 %), P. agri PB92T (97.9 %), P. terrae DS-57T (97.5 %), P. suwonensis 15-52T (97.4 %), P. sandarakinus DS-27T (97.0 %) and P. soli 15-51T (97.0 %), but DNA relatedness between strain THG-45T and these strains was below 36 %. The G+C content of the genomic DNA was 39 mol%. The only isoprenoid quinone detected in strain THG-45T was menaquinone-7 (MK-7). The predominant fatty acids were iso-C15 : 0, summed feature 3 (comprising C16 : 1ω6c and/or C16 : 1ω7c) and iso-C17 : 0 3-OH, and the major polar lipids were phosphatidylethanolamine and an unidentified aminophosphoglycolipid. Phenotypic data and phylogenetic inference supported the affiliation of strain THG-45T to the genus Pedobacter , and a number of biochemical tests differentiated strain THG-45T from the recognized species of the genus Pedobacter . Therefore, the novel isolate represents a novel species, for which the name Pedobacter ginsenosidimutans sp. nov. is proposed, with THG-45T as the type strain ( = KACC 14530T = JCM 16721T).

Heated Soil

A strictly aerobic, thermophilic, moderately acidophilic, non-spore-forming bacterium, strain P373T, was isolated from geothermally heated soil at Waikite, New Zealand. Cells were filamentous rods, 0.2–0.4 µm in diameter and grew in chains up to 80 µm in length. On the basis of 16S rRNA gene sequence similarity, strain P373T was shown to belong to the family Chitinophagaceae (class Sphingobacteriia ) of the phylum Bacteroidetes , with the most closely related cultivated strain, Chitinophaga pinensis UQM 2034T, having 87.6 % sequence similarity. Cells stained Gram-negative, and were catalase- and oxidase-positive. The major fatty acids were i-15 : 0 (10.8 %), i-17 : 0 (24.5 %) and i-17 : 0 3-OH (35.2 %). Primary lipids were phosphatidylethanolamine, two unidentified aminolipids and three other unidentified polar lipids. The presence of sulfonolipids (N-acyl-capnines) was observed in the total lipid extract by mass spectrometry. The G+C content of the genomic DNA was 47.3 mol% and the primary respiratory quinone was MK-7. Strain P373T grew at 35–63 °C with an optimum temperature of 60 °C, and at pH 5.5–8.7 with an optimum growth pH of 7.3–7.4. NaCl tolerance was up to 5 % (w/v) with an optimum of 0.1–0.25 % (w/v). Cell colonies were non-translucent and pigmented vivid yellow–orange. Cells displayed an oxidative chemoheterotrophic metabolism. The distinct phylogenetic position and the phenotypic characteristics separate strain P373T from all other members of the phylum Bacteroidetes and indicate that it represents a novel species in a new genus, for which the name Thermoflavifilum aggregans gen. nov., sp. nov. is proposed. The type strain of the type species is P373T ( = ICMP 20041T = DSM 27268T).

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. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain PTJT-5T was a member of the phylum Bacteroidetes , exhibiting the highest sequence similarity to Lacibacter cauensis NJ-8T (87.7 %). 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.

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 strictly aerobic, Gram-stain-negative bacterium, designated strain No.6T, was isolated from a lichen (Cladonia sp.) collected in Geogeum Island, Korea, and its taxonomic status was established by a polyphasic study. Cells of strain No.6T were non-motile, catalase- and oxidase-positive, non-spore-forming rods. Growth was observed at 15–35 °C (optimum, 25–30 °C), at pH 5.0–10.0 (optimum, pH 6.0–8.0) and with 0–3 % NaCl (optimum, 0–2 %). The predominant cellular fatty acids were summed feature 3 (comprising iso-C15 : 0 2-OH and/or C16 : 1ω7c, 41.5 %), iso-C15 : 0 (26.7 %) and C16 : 0 (9.6 %), and menaquinone MK-7 was the only respiratory quinone. The G+C content of the genomic DNA of strain No.6T was 36.8 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain No.6T fell within the evolutionary group encompassed by the genus Sphingobacterium . Levels of 16S rRNA gene sequence similarity between the novel strain and the type strains of recognized Sphingobacterium species ranged from 92.1 to 99.1 %, the highest values being with Sphingobacterium siyangense SY1T (99.1 %) and Sphingobacterium multivorum IAM 14316T (98.5 %). DNA–DNA relatedness between strain No.6T and these two type strains were 32.0 and 5.7 %, respectively. The polar lipids found in strain No.6T were phosphatidylethanolamine, two unidentified phospholipids, three unidentified aminophospholipids, one glycolipid and four unidentified lipids. One unidentified sphingolipid was also found. On the basis of phenotypic and genotypic data, strain No.6T represents a novel species of the genus Sphingobacterium , for which the name Sphingobacterium cladoniae sp. nov. is proposed. The type strain is No.6T ( = KCTC 22613T = JCM 16113T). An emended description of Sphingobacterium siyangense is also proposed.

Emended Description

A Gram-staining-negative, strictly aerobic, rod-shaped, non-flagellated, non-spore-forming and gliding marine bacterium designated strain CC-AMZ-301T was isolated from coastal surface seawater near Taichung harbour, Taiwan. Strain CC-AMZ-301T predominantly synthesized zeaxanthin and thus formed yellow colonies on marine agar. The novel strain showed high pairwise 16S rRNA gene sequence similarity to Kordia periserrulae IMCC1412T (95.0 %), K. algicida KCTC 8814PT (94.4 %) and K. antarctica IMCC3317T (94.2 %), and formed a phylogenetic lineage tightly associated with species of the genus Kordia . The polar lipid profile of strain CC-AMZ-301T consisted of three unidentified lipids, three unidentified aminolipids and one unidentified phospholipid. The major fatty acids (>5 % of total) were iso-C17 : 0 3-OH, iso-C15 : 0, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and summed feature 9 (iso-C17 : 1ω9c and/or 10-methyl C16 : 0). The DNA G+C content was 36.4 mol%. Menaquinone 6 (MK-6) was the predominant respiratory quinone. The major polyamine was the triamine sym-homospermidine. Based on evidence from the present polyphasic study, strain CC-AMZ-301T is proposed to represent a novel species of the genus Kordia , for which the name Kordia aquimaris sp. nov. is proposed; the type strain is CC-AMZ-301T ( = JCM 18556T = BCRC 80464T). An emended description of the genus Kordia is also proposed.

Two Gram-positive-staining, rod-shaped, endospore-forming isolates (UG-2T and UG-3), with an optimum growth temperature of around 37 °C and an optimum pH for growth of about 4, were recovered from an acidic effluent of the uranium mill tailing at Urgeiriça in Central Portugal. On the basis of 16S rRNA gene sequence similarity, the strains belonged to the family Sporolactobacillaceae and were closely related to Pullulanibacillus naganoensis ATCC 53909T (97.9 %). Unlike P. naganoensis , strains UG-2T and UG-3 grew in medium containing up to 5000 p.p.m. U(VI) but did not hydrolyse pullulan. Chemotaxonomic data also supported the affiliation of strains UG-2T and UG-3 to the genus Pullulanibacillus . Physiological and biochemical tests along with fatty acid composition allowed differentiation of strains UG-2T and UG-3 from P. naganoensis . It is suggested that strains UG-2T and UG-3 represent a novel species, for which the name Pullulanibacillus uraniitolerans is proposed; the type strain is UG-2T ( = DSM 19429T = LMG 24205T). An emended description of the genus Pullulanibacillus is also proposed.

A yellow-pigmented, Gram-staining-negative, strictly aerobic, rod-shaped, non-flagellated, non-spore-forming, lipolytic and gliding marine bacterium designated strain CC-AMWY-103BT was isolated from surface seawater collected at Kending, Taiwan. The strain shared the highest 16S rRNA gene sequence similarity of 89.4 % with Owenweeksia hongkongensis JCM 12287T and Brumimicrobium mesophilum YH207T, and established a distinct phyletic lineage associated with the members of the family Cryomorphaceae . The polar lipid profile of strain CC-AMWY-103BT consisted of phosphatidylethanolamine, ten unidentified lipids and four unidentified aminolipids. The major fatty acids (>5 % of the total) were iso-C15 : 0, iso-C15 : 1 G, C15 : 1ω5c, iso-C17 : 0 3-OH and C15 : 1ω8c. The DNA G+C content was 44.2±0.3 mol%. The predominant respiratory quinone was menaquinone-6 (MK-6) and the major polyamine was spermidine. Based on its genetic, phylogenetic, phenotypic and chemotaxonomic distinctiveness, strain CC-AMWY-103BT is proposed to represent a distinct member of the family Cryomorphaceae , for which the name Luteibaculum oceani gen. nov., sp. nov. is proposed; the type strain of Luteibaculum oceani is CC-AMWY-103BT ( = JCM 18817T = BCRC 80551T).

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.
