The 16S Rrna Gene

A Gram-stain-positive, aerobic, short rod-shaped bacterium, strain ZD1-4T, was isolated from the Zhadang Glacier snow pit. The 16S rRNA gene sequence of the isolate showed highest similarity (98.8 %) to that of Mycetocola manganoxydans MB1-14T. The major fatty acids of strain ZD1-4T were anteiso-C15 : 0, C16 : 0, C18 : 0 and anteiso-C17 : 0. It possessed diphosphatidylglycerol as one of the major polar lipids, and MK-10 and MK-11 as the predominant isoprenoid quinones. The DNA G+C content of strain ZD1-4T was 63.8±0.2 mol% (T m). A number of phenotypic characteristics distinguished this bacterium from the type strains of other species of the genus Mycetocola . Moreover, the novel isolate showed only approximately 50 % DNA–DNA relatedness with M. manganoxydans MB1-14T. According to these genotypic and phenotypic data, it is evident that strain ZD1-4T represents a novel species of the genus Mycetocola , for which the name Mycetocola zhadangensis sp. nov. is proposed. The type strain is ZD1-4T ( = KACC 16570T = CGMCC 1.12042T).

A novel actinobacterium, designated strain BR-34T, was isolated from rhizosphere soil of bamboo (Phyllostachys nigro var. henonis) sampled in Damyang, Korea. The strain was found to have morphological and chemotaxonomic characteristics typical of the genus Catenulispora . The strain contained iso-C16 : 0 as the major fatty acid and MK-9(H4), MK-9(H6) and MK-9(H8) as major isoprenoid quinones. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain BR-34T formed a cluster separate from members of the genus Catenulispora and was related most closely to Catenulispora acidiphila ID139908T (97.4 % similarity), Catenulispora rubra Aac-30T (97.3 %), Catenulispora yoronensis TT N02-20T (97.3 %) and Catenulispora subtropica TT 99-48T (97 %). However, the level of DNA–DNA relatedness between strain BR-34T and C. acidiphila ID139908T was only 45.32 %. Based on DNA–DNA relatedness, morphological and phenotypic data, strain BR-34T could be distinguished from the type strains of phylogenetically related species. It is therefore considered to represent a novel species of the genus Catenulispora , for which the name Catenulispora graminis sp. nov. is proposed. The type strain is BR-34T ( = KACC 15070T = NBRC 107755T).

The 16S Rrna Gene

A novel obligately anaerobic, thermophilic and formate-utilizing bacterium K32T was isolated from Shengli oilfield of China. Cells were straight rods (0.4–0.8 µm × 2.5–8.0 µm), Gram-stain-positive, non-spore-forming and slightly motile. Optimum growth occurred with pH of 7 and 0.5 g l–1 NaCl under temperature of 55–60 °C. Nitrate could be reduced into nitrite, syntrophic formate oxidation to methane and carbon dioxide occurred when co-culturing strain K32T and Methanothermobacter thermautotrophicus ΔH. The main cellular fatty acids were iso-C15 : 0 (24.0 %), anteiso-C15 : 0 (21.7 %), C16 : 0 (12.7 %) and C14 : 0 (10.8 %), and the main polar lipid was phosphatidylglycerol. The G+C content of the genomic DNA was 46.3 mol%. The 16S rRNA gene sequence of K32T shared ≤90.4 % of sequence similarity to closest type strains of Desulfitibacter alkalitolerans , Calderihabitans maritimus and members of the genus Moorella . Based on the phenotypic, biochemical and genotypic characterization, Zhaonella formicivorans gen. nov., sp. nov. is proposed with K32T (=CCAM 584T =DSM 107278T=CGMCC1.5297T) as the type strain, which is the first representative of Zhaonellaceae fam. nov. In addition, the order Thermoanaerobacterales and family Peptococcaceae were reclassified, and three novel families in the novel order of Moorellales ord. nov. were also proposed.

A Gram-stain-negative, rod-shaped, aerobic, non-motile bacterium, designated Y620-1T, was isolated from a glacier on the Tibetan Plateau, China. The 16S rRNA gene sequence of the novel isolate shared 93.6–95.1 % similarity with type strains of species of the genus Dyadobacter . The major fatty acids of strain Y620-1T were summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH), iso-C15 : 0, C16 : 1ω5c and iso-C17 : 0 3-OH. The predominant isoprenoid quinone and polar lipid were MK-7 and phosphatidylethanolamine (PE), respectively. The DNA G+C content was 44.4±0.3 mol% (T m). Flexirubin-type pigment was produced. The novel isolate was classified in the genus Dyadobacter , but a number of phenotypic characteristics distinguished the novel isolate from type strains of species of the genus Dyadobacter . From these genotypic and phenotypic data, it is evident that strain Y620-1T represents a novel species of the genus Dyadobacter , for which the name Dyadobacter tibetensis sp. nov. is proposed. The type strain is Y620-1T ( = JCM 18589T = CGMCC 1.12215T).

A Gram-negative, rod-shaped, aerobic, motile bacterium, strain Y1243-1T, was isolated from an ice core drilled from Yuzhufeng Glacier, Tibetan Plateau, China. Cells had polar flagella. The novel strain shared 94.7–97.6 % 16S rRNA gene sequence similarity with the type strains of species of the genus Massilia . The novel isolate is thus classified in the genus Massilia . The major fatty acids of strain Y1243-1T were summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH) (43.98 %), C16 : 0 (27.86 %), C10 : 0 3-OH (7.10 %), C18 : 0 (6.95 %) and C18 : 1ω7c (5.01 %). The predominant isoprenoid quinone was Q-8. The DNA G+C content of strain Y1243-1T was 65.7 mol% (T m). The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol. A number of phenotypic characteristics distinguished the novel isolate from the type strains of recognized Massilia species. Furthermore, in DNA–DNA hybridization tests, strain Y1243-1T shared 45 % relatedness with its closest phylogenetic relative, Massilia consociata CCUG 58010T. From the genotypic and phenotypic data, it is evident that strain Y1243-1T represents a novel species of the genus Massilia , for which the name Massilia yuzhufengensis sp. nov. is proposed. The type strain is Y1243-1T ( = KACC 16569T = CGMCC 1.12041T).

Enrichment cultures inoculated with hydrothermally influenced nearshore sediment from Papua New Guinea led to the isolation of an arsenic-tolerant, acidophilic, facultatively aerobic bacterial strain designated PNG-AprilT. Cells of this strain were Gram-stain-negative, rod-shaped, motile and did not form spores. Strain PNG-AprilT grew at temperatures between 4 °C and 40 °C (optimum 30–37 °C), at pH 3.5 to 8.3 (optimum pH 5–6) and in the presence of up to 2.7 % NaCl (optimum 0–1.0 %). Both arsenate and arsenite were tolerated up to concentrations of at least 0.5 mM. Metabolism in strain PNG-AprilT was strictly respiratory. Heterotrophic growth occurred with O2 or nitrate as electron acceptors, and aerobic lithoautotrophic growth was observed with thiosulfate or nitrite as electron donors. The novel isolate was capable of N2-fixation. The respiratory quinones were Q-8 and Q-7. Phylogenetically, strain PNG-AprilT belongs to the genus Burkholderia and shares the highest 16S rRNA gene sequence similarity with the type strains of Burkholderia fungorum (99.8 %), Burkholderia phytofirmans (98.8 %), Burkholderia caledonica (98.4 %) and Burkholderia sediminicola (98.4 %). Differences from these related species in several physiological characteristics (lipid composition, carbohydrate utilization, enzyme profiles) and DNA–DNA hybridization suggested the isolate represents a novel species of the genus Burkholderia , for which we propose the name Burkholderia insulsa sp. nov. The type strain is PNG-AprilT ( = DSM 28142T = LMG 28183T).

A Gram-stain-negative, aerobic, motile, short rod-shaped, catalase-negative and oxidase-positive bacterium, strain CAU 1568T, was isolated from marine sediment sand sampled at Sido Island in the Republic of Korea. The optimum conditions for growth were at 25–30 °C, at pH 6.5–8.5 and with 0–4.0 % (w/v) NaCl. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that strain CAU 1568T was a member of the genus Photobacterium with high similarity to Photobacterium salinisoli JCM 30852T (97.7 %), Photobacterium halotolerans KACC 17089T (97.3 %) and Photobacterium galatheae LMG F28894T (97.3 %). The predominant cellular fatty acids were C16 : 0, summed feature 3 (C16 : 1  ω6c and/or C16 : 1  ω7c) and summed feature 8 (C18 : 1  ω7c and/or C18 : 1  ω6c), with Q-8 as the major of isoprenoid quinone. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylglycerols, phosphatidylcholine, phosphatidylethanolamine, phospholipid, two aminophospholipids and three unidentified lipids. The whole genome size of strain CAU 1568T was 4.8 Mb with 50.1 mol% G+C content; including 38 contigs and 4233 protein-coding genes. These taxonomic data support CAU 1568T as representing a novel Photobacterium species, for which the name Photobacterium arenosum sp. nov. is proposed. The type strain of this novel species is CAU 1568T (=KCTC 82404T=MCCC 1K05668T).

A novel actinobacterium, designated strain F22T, was isolated from grassland soil collected from the Ziwuling area on the Loess Plateau, China. The novel strain was found to have morphological and chemotaxonomic characteristics typical of members of the genus Streptomyces . Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain F22T belonged to the genus Streptomyces , being most closely related to Streptomyces resistomycificus NBRC 12814T (98.28 % sequence similarity), Streptomyces ciscaucasicus NBRC 12872T (98.14 %), Streptomyces chartreusis NBRC 12753T (98.14 %) and Streptomyces canus NRRL B-1989T (98.14 %). In DNA–DNA hybridizations and comparisons of morphological and phenotypic data, strain F22T could be distinguished from all of its closest phylogenetic relatives. Strain F22T exhibited antibacterial and antifungal activity, especially against Staphylococcus aureus , Bacillus subtilis and Cylindrocarpon destructans. Based on the DNA–DNA hybridization data and morphological, phenotypic and phylogenetic evidence, strain F22T represents a novel species of the genus Streptomyces , for which the name Streptomyces ziwulingensis sp. nov. is proposed. The type strain is F22T ( = CCNWFX 0001T = JCM 18081T = ACCC41875T).

Two actinomycete strains, BK125T and BK199T, isolated from a hay meadow soil sample were investigated to determine their taxonomic position using a polyphasic approach. The isolates produced greenish-yellow and light green aerial mycelium on oatmeal agar, respectively. They contained anteiso-C15 : 0, iso-C15 : 0 and C16 : 0 as the major fatty acids, and MK-9 (H6) and MK-9 (H8) as the predominant isoprenoid quinones. Phylogenetic analysis of the 16S rRNA gene sequences showed that the isolates formed distinct phyletic lines towards the periphery of the Streptomyces prasinus subclade. Analysis of DNA–DNA relatedness between the two isolates showed that they belonged to different genomic species. The organisms were also distinguished from one another and from type strains of species classified in the S. prasinus subclade using a combination of genotypic and phenotypic properties. On the basis of these data, it is proposed that the isolates be assigned to the genus Streptomyces as Streptomyces chlorus sp. nov. and Streptomyces viridis sp. nov. with isolates BK125T ( = KACC 20902T = CGMCC 4.5798T) and BK199T ( = KACC 21003T = CGMCC 4.6824T) as the respective type strains.

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).

Genomic Relatedness

Two species of the genus Deinococcus , namely Deinococcus wulumuqiensis Wang et al. 2010 and Deinococcus xibeiensis Wang et al. 2010, were simultaneously proposed and described in the same publication. However, the identical 16S rRNA gene sequence of the two type strains strongly raised the probability of their relatedness at the species level. Thus, the genomic relatedness of the two species of the genus Deinococcus was investigated here to clarify their taxonomic status. The high (99.9 %) average nucleotide identity (ANI) between the genome sequences of the two type strains suggested that the two species are synonymous. Additional phenotypic data including enzymic activities and substrate-utilization profiles showed no pronounced differences between the type strains of the two species. Data from this study demonstrated that the two taxa constitute a single species. According to Rule 42 of the Bacteriological Code, we propose that D. xibeiensis Wang et al. 2010 should be reclassified as a subjective heterotypic synonym of D. wulumuqiensis Wang et al. 2010.
