Arthrobacter Nicotinovorans

A Gram-stain-positive, aerobic, motile by gliding, rod-shaped bacterial strain, THG-GM18T, was isolated from soil of a bamboo grove. Strain THG-GM18T was able to grow in the presence of up to 6.0 % (w/v) NaCl, at 4–37 °C and at pH 7.0–10.0 in R2A medium. Based on 16S rRNA gene sequence similarity, strain THG-GM18T was closely related to species of the genus Arthrobacter . The most closely related strains to strain THG-GM18T are Arthrobacter ramosus CCM 1646T (98.5 % similarity), Arthrobacter nitroguajacolicus G2-1T (98.4 %), Arthrobacter nicotinovorans DSM 420T (98.2 %), Arthrobacter aurescens DSM 20116T (98.1 %) and Arthrobacter chlorophenolicus A6T (98.0 %). Strain THG-GM18T possessed chemotaxonomic properties consistent with those of members of the genus Arthrobacter , such as peptidoglycan type A3α (l-Lys–l-Ala–l-Thr–l-Ala), MK-9 as major menaquinone and anteiso- and iso-branched compounds (anteiso-C15 : 0, iso-C16 : 0 and anteiso-C17 : 0) as major cellular fatty acids. The polar lipid profile contained diphosphatidylglycerol, phosphatidylglycerol, an unidentified phosphoglycolipid, unidentified phospholipids, unidentified aminolipids, an unidentified glycolipid and unidentified lipids. The G+C content of the genomic DNA was 61.0 mol%. The DNA–DNA relatedness values between strain THG-GM18T and its closest phylogenetic neighbours were below 26.0 %. The results of physiological and biochemical tests allowed the differentiation of strain THG-GM18T from species of the genus Arthrobacter with validly published names. Arthrobacter bambusae sp. nov. is the proposed name, and the type strain is THG-GM18T ( = KACC 17531T = JCM 19335T).

Two Gram-stain-positive, non-endospore-forming actinobacteria (Ca8Tand Ca14) were isolated from a bioreactor with extensive phosphorus removal. Based on 16S rRNA gene sequence similarity comparisons, strains Ca8T and Ca14 were shown to belong to the genus Gordonia and were most closely related to Gordonia hirsuta DSM 44140T (98.0 % sequence similarity) and Gordonia hydrophobica DSM 44015T (97.2 %). In comparison with the sequences of the type strains of all other species of the genus Gordonia tested, similarities were below 97 %. The quinone systems of the strains were determined to consist predominantly of MK-9H2. The polar lipid profile for both organisms consisted of diphosphatidylglycerol, phosphatidylglycerol, phospatidylethanolamine, phosphatidylinositol and phosphatidylinositol mannoside. Whole-organism hydrolysates contained meso-diaminopimelic acid as the diamino acid of the peptidoglycan; mycolic acids were detected as well. These chemotaxonomic traits and the major fatty acids, which were C16 : 1 cis-9, C16 : 0 and C18 : 1 and tuberculostearic acid strongly supported the grouping of strains Ca8T and Ca14 into the genus Gordonia . The two strains showed a DNA–DNA similarity of 96 %. DNA–DNA hybridizations of strain Ca8T with G. hirsuta DSM 44140T and G. hydrophobica DSM 44015T resulted in values of 26.3 and 25.0 %, respectively. These results and those of the physiological and biochemical tests allowed a clear phenotypic differentiation of strains Ca8T and Ca14 from the most closely related species of the genus Gordonia . It is concluded that strains Ca8T and Ca14 represent a novel species, for which the name Gordonia phosphorivorans sp. nov. is proposed, with the type strain Ca8T ( = DSM 45630T = CCUG 61533T = CCM 7957T = LMG 26648T).

A Gram-positive, non-spore-forming actinobacterium (01-Gi-040T) isolated from an indoor wall was studied to examine its taxonomic position. The isolate formed a very rudimentary substrate-mycelium that fragmented into rod-shaped to coccoid cells. On the basis of the 16S rRNA gene sequence similarity studies, strain 01-Gi-040T was shown to belong to the genus Ornithinimicrobium closely related to Ornithinimicrobium kibberense K22-20T (97.1 %), Ornithinimicrobium humiphilum DSM 12362T (96.2 %) and Ornithinimicrobium pekingense LW6T (96.1 %). A close relationship was also found with Arsenicicoccus bolidensis CCUG 47306T (95.9 %) and Arsenicicoccus piscis Kis4-19T (95.7 %) and a moderate relationship to the type strains of the genus Serinicoccus (94.0–94.1 %). The predominant menaquinone of strain 01-Gi-040T was MK-8(H4). The peptidoglycan contained ornithine as the diagnostic diamino acid. The polar lipid profile consisted of the lipids phosphatidylinositol, phosphatidylglycerol, diphosphatidylglycerol, an unknown phospholipid, an unknown aminolipid and two unknown phosphoglycolipids. The major fatty acids iso-C15 : 0, iso-C16 : 0 and iso-C17 : 0 were consistent with the fatty acid patterns reported for members of the genus Ornithinimicrobium . The results of DNA–DNA hybridizations, physiological and biochemical tests allowed phenotypic differentiation of strain 01-Gi-040T from the three recognized species of the genus Ornithinimicrobium . Strain 01-Gi-040T represents a novel species of the genus Ornithinimicrobium , for which we propose the name Ornithinimicrobium murale sp. nov., with the type strain 01-Gi-040T ( = DSM 22056T = CCM 7610T).

A bacterial strain, isolated from a sample of reef-building coral (Isopora palifera) collected off the coast of southern Taiwan, was characterized using a polyphasic taxonomic approach. The strain, designated sw-2T, was Gram-staining-negative, aerobic, rod-shaped and motile, with subpolar flagella, and formed greyish pink colonies. Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain sw-2T was most closely related to Roseivivax halodurans Och 239T (97.4 % sequence similarity) and Roseivivax halotolerans Och 210T (96.4 %). The novel strain did not require NaCl for growth and exhibited optimal growth at 35–40 °C, at pH 7.5–8.0 and with 3–7 % (w/v) NaCl. It produced bacteriochlorophyll a under aerobic conditions. Summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c; 63.7 %) predominated in the cellular fatty acid profile. The novel strain’s major respiratory quinone was ubiquinone Q-10 and its genomic DNA G+C content was 68.8 mol%. The polar lipid profile consisted of a mixture of phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, diphosphatidylglycerol, phosphatidyldimethylethanolamine, sulfo-quinovosyl diacylglycerol and three uncharacterized phospholipids. The level of DNA–DNA relatedness between strain sw-2T and Roseivivax halodurans Och 239T was only 15.0 %. The results of physiological and biochemical tests allowed the clear phenotypic differentiation of the novel strain from all established species of the genus Roseivivax . Based on the genotypic, phenotypic and chemotaxonomic data, strain sw-2T represents a novel species in the genus Roseivivax , for which the name Roseivivax isoporae sp. nov. is proposed. The type strain is sw-2T ( = LMG 25204T = BCRC 17966T).

A novel Gram-stain-negative, aerobic, rod-shaped strain designated PG04T was isolated from the rhizosphere of watermelon plants cultivated in Beijing, China. A polyphasic taxonomic study was performed on the new isolate. On the basis of 16S rRNA gene sequence similarity studies, isolate PG04T belonged clearly to the genus Hansschlegelia and was most closely related to Hansschlegelia zhihuaiae (97.3 % similarity to the type strain). The predominant respiratory quinone was ubiquinone 10 (Q-10) and the polar lipid profile was composed of the major lipids diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and phosphatidylcholine. The major fatty acids were C18 : 1ω7c (41.3 %), C19 : 0 cyclo ω8c (30.6 %) and C16 : 0 (19.1 %). The G+C content of the DNA was about 64.4 mol%. DNA–DNA hybridization experiments showed 34.4 % relatedness between strain PG04T and H. zhihuaiae DSM 18984T. The results of physiological and biochemical tests and differences in fatty acid profiles allowed clear phenotypic differentiation of strain PG04T from the most closely related species in the genus, H. zhihuaiae . Strain PG04T therefore represents a novel species within the genus Hansschlegelia , for which the name Hansschlegelia beijingensis sp. nov. is proposed, with the type strain PG04T ( = DSM 25481T = ACCC 05759T).

A Gram-stain-positive bacterium, strain RV15T, forming an extensively branched substrate mycelium and aerial hyphae that differentiate into spiral chains of spores, was isolated from a marine sponge Dysidea tupha collected from Rovinj (Croatia). Comparison of 16S rRNA gene sequences showed that strain RV15T is a member of the genus Streptomyces with highest sequence similarity to the type strains of Streptomyces caeruleatus (98.8 %), Streptomyces cyaneochromogenes (98.6 %) and Streptomyces shaanxiensis (98.5 %). Sequence similarities to all other Streptomyces types strains were below 98.5 %. The multilocus sequence analysis-based evolutionary distance, the average nucleotide identity value and the genome-to-genome distance of strain RV15T and the type strain of S. caeruleatus were clearly below the species cut-off values. Strain RV15T exhibited a quinone system composed of the major menaquinones MK-9(H4), MK-9(H6) and MK-9(H2), typical for the genus Streptomyces . The polar lipid profile of strain RV15T consisted of the predominant compounds diphosphatidylglycerol and phosphatidylethanolamine, moderate amounts of phosphatidylinositol, phosphatidylinositol mannoside, an unidentified lipid and an unidentified phospholipid. Major polyamines were spermine and spermidine. The diagnostic diaminoacid of the peptidoglycan was meso-diaminopimelic acid. The major fatty acids were iso C16 : 0, anteiso C17 : 1 ω9c and anteiso C17 : 0. The results of physiological and biochemical tests allowed further phenotypic differentiation of strain RV15T from its most-related species and hence clearly merits species status. We propose the name Streptomyces dysideae sp. nov. with the type strain RV15T (=DSM 42110T=LMG 27702T).

A Gram-positive, non-spore-forming actinobacterium (IMT-300T) was isolated from soil amended with humic acid in Malvern, AL, USA. This soil has been used for 50+years for the cultivation of earthworms for use as fish bait. Based on 16S rRNA gene sequence similarity studies, strain IMT-300T was shown to belong to the genus Leucobacter and was closely related to the type strain of ‘Leucobacter margaritiformis’ L1T (97.8%). Similarity to all other type strains of Leucobacter species was lower than 97.2 %. The average nucleotide identity (ANI) and digital DNA–DNA hybridization (dDDH) values between the IMT-300T genome assembly and those of the closest relative Leucobacter type strain were 81.4 and 23.3 % ( Leucobacter chironomi ), respectively. The peptidoglycan of strain IMT-300T contained l-2,4-diaminobutyric acid as the diagnostic diamino acid. In addition, glycine, d- and l-alanine and d-glutamic acid were found. The peptidoglycan type represents a variant of B2δ (B11). The major quinones were menaquinones MK-10 and MK-11. The polar lipid profile consisted of the major lipids diphosphatidylglycerol, phosphatidylglycerol and moderate to minor amounts of two unidentified phospholipids, two unidentified glycolipids and an unidentified aminophospholipid. The polyamine pattern contained major amounts of spermidine and spermine. Strain IMT-300T contained the major fatty acids C15 : 0 anteiso, C16 : 0 iso and C17 : 0 anteiso, like other members of the genus Leucobacter . The results of ANI and dDDH analyses and physiological and biochemical tests allowed a genotypic and phenotypic differentiation of strain IMT-300T from the most closely related Leucobacter species. Strain IMT-300T represents a novel Leucobacter species, for which we propose the name Leucobacter soli sp. nov., with the type strain IMT-300T (CIP 111803T=DSM 110505T=CCM 9020T=LMG 31600T).

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.

A bacterial strain, designated Dd16T, was isolated from a hexachlorocyclohexane (HCH) dumpsite at Lucknow, India. Cells of strain Dd16T were Gram-stain-negative, non-motile, rod-shaped and yellow-pigmented. Phylogenetic analysis based on 16S rRNA gene sequences showed that the strain belonged to the genus Sphingomonas in the family Sphingomonadaceae , as it showed highest sequence similarity to Sphingomonas asaccharolytica IFO 15499T (95.36 %), Sphingosinicella vermicomposti YC7378T (95.30), ‘Sphingomonas humi’ PB323 (95.20 %), Sphingomonas sanxanigenens NX02T (95.14 %) and Sphingomonas desiccabilis CP1DT (95.00 %). The major fatty acids were summed feature 3 (C16 : 1ω7c/C16 : 1ω6c) C14 : 0 2-OH, summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c) and C16 : 0. The polar lipid profile of strain Dd16T also corresponded to those reported for species of the genus Sphingomonas (phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol, and a sphingoglycolipid), again supporting its identification as a member of the genus Sphingomonas . The predominant respiratory quinone was ubiquinone Q10, and sym-homospermidine was the major polyamine observed. The total DNA G+C content of strain Dd16T was 65.8 mol%. The results obtained on the basis of phenotypic characteristics and phylogenetic analysis and after biochemical and physiological tests, clearly distinguished strain Dd16T from closely related members of the genus Sphingomonas . Thus, strain Dd16T represents a novel species of the genus Sphingomonas for which the name Sphingomonas indica sp. nov. is proposed. The type strain is Dd16T ( = DSM 25434T = CCM 7882T).
