Taxonomic Approach

A novel actinobacterium, strain A8036T, isolated from soil, was investigated by using a polyphasic taxonomic approach. The organism formed extensively branched substrate hyphae that generated spiral chains of spores with irregular surfaces. The cell wall contained meso-diaminopimelic acid (type III) and cell-wall sugars were glucose, madurose, mannose and ribose. The predominant menaquinones were MK-9(H6) and MK-9(H4). The phospholipids were diphosphatidylglycerol, phosphatidylinositol and phosphatidylinositol mannosides. The major cellular fatty acids were iso-C16 : 0, C17 : 1 cis9, C16 : 0, C15 : 0 and 10-methyl C17 : 0. Based on 16S rRNA gene sequence analysis, the closest phylogenetic neighbours of strain A8036T were Actinomadura meyerae DSM 44715T (99.23 % similarity), Actinomadura bangladeshensis DSM 45347T (98.9 %) and Actinomadura chokoriensis DSM 45346T (98.3 %). However, DNA–DNA relatedness and phenotypic data demonstrated that strain A8036T could be clearly distinguished from the type strains of all closely related Actinomadura species. Strain A8036T is therefore considered to represent a novel species of the genus Actinomadura , for which the name Actinomadura geliboluensis sp. nov. is proposed. The type strain is A8036T ( = DSM 45508T = KCTC 19868T).

Actinomycete Strain

A novel actinomycete, strain DS3030T, was isolated from a deep sediment sample, collected from the southern Black Sea coast, Turkey, and was examined using a polyphasic approach. On the basis of 16S rRNA gene sequence analysis, strain DS3030T was shown to belong to the genus Saccharomonospora and to be related most closely to Saccharomonospora marina XMU15T (99.6 % similarity). Sequence similarities with other strains of the genus Saccharomonospora were lower than 97.0 %. The organism had chemical and morphological features typical of the genus Saccharomonospora . The cell wall of the novel strain contained meso-diaminopimelic acid, arabinose and galactose as diagnostic sugars. The polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol and phosphatidylinositol mannoside. The predominant menaquinone was MK-9(H4). Major fatty acids were iso-C16 : 0, iso-C16 : 0 2-OH and C16 : 1 cis 9. Phenotypic data clearly distinguished the new isolate from its closest relative, S. marina XMU15T. The combined genotypic and phenotypic data and low DNA–DNA relatedness with its closest related strain reveal that strain DS3030T represents a novel species of the genus, for which the name Saccharomonospora amisosensis sp. nov. is proposed. The type strain is DS3030T ( = DSM 45685T = KCTC 29069T = NRRL B-24885T).

Genotypic Characteristics

Three novel actinomycete strains, designated as DR6-1T, DR6-2 and DR6-4, isolated from the roots of Dendrobium heterocarpum Lindl in Thailand were studied using a polyphasic taxonomic approach. The strains grew at 20–37 °C, at pH 5–10 and with 5 % (w/v) NaCl. They contained meso-diaminopimelic acid in the cell-wall peptidoglycan and MK-9(H4) was a major menaquinone. Arabinose and galactose were the major sugars in the cell wall. The predominant cellular fatty acids were iso-C16 : 0 and iso-C15 : 0. The detected polar lipids were diphosphatidylglycerol, hydroxyphosphatidylethanolamine, phosphatidylethanolamine, phosphatidylinositol and phosphatidylglycerol. Strains DR6-1T, DR6-2 and DR6-4 shared 99.9–100 % 16S rRNA gene sequence similarity and were closely related to Amycolatopsis echigonensis JCM 21831T (98.7-98.8%). The approximate genome size of strain DR6-1T was 9.6 Mb with a G+C content of 69.6 mol%. The ANIb and dDDH values between genomic sequences of strain DR6-1T and Amycolatopsis echigonensis JCM21831T, Amycolatopsis rubida JCM 10871T and Amycolatopsis nivea KCTC 39515T were 90.55, 92.25, 92.60%, and 47.20, 52.10 and 52.50%, respectively. Based on the phenotypic, chemotaxonomic and genotypic characteristics, it has been concluded that strains DR6-1T, DR6-2 and DR6-4 represent a novel species of the genus Amycolatopsis for which the name Amycolatopsis dendrobii sp. nov. is proposed. The type strain is DR6-1T (=JCM 33742T=KCTC 49546T=TISTR 2840T).

Gene Sequence Analysis

The taxonomic positions of two novel aerobic, Gram-stain-positive Actinobacteria, designated RB20T and RB56T, were determined using a polyphasic approach. Both were isolated from the fungus-farming termite Macrotermes natalensis. Results of 16S rRNA gene sequence analysis revealed that both strains are members of the genus Nocardia with the closest phylogenetic neighbours Nocardia miyunensis JCM12860T (98.9 %) and Nocardia nova DSM44481T (98.5 %) for RB20T and Nocardia takedensis DSM 44801T (98.3 %), Nocardia pseudobrasiliensis DSM 44290T (98.3 %) and Nocardia rayongensis JCM 19832T (98.2 %) for RB56T. Digital DNA–DNA hybridization (DDH) between RB20T and N. miyunensis JCM12860T and N. nova DSM 44481T resulted in similarity values of 33.9 and 22.0 %, respectively. DDH between RB56T and N. takedensis DSM44801T and N. pseudobrasiliensis DSM44290T showed similarity values of 20.7 and 22.3 %, respectively. In addition, wet-lab DDH between RB56T and N. rayongensis JCM19832T resulted in 10.2 % (14.5 %) similarity. Both strains showed morphological and chemotaxonomic features typical for the genus Nocardia , such as the presence of meso-diaminopimelic acid (A2pm) within the cell wall, arabinose and galactose as major sugar components within whole cell-wall hydrolysates, the presence of mycolic acids and major phospholipids (diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol), and the predominant menaquinone MK-8 (H4, ω-cyclo). The main fatty acids for both strains were hexadecanoic acid (C16 : 0), 10-methyloctadecanoic acid (10-methyl C18 : 0) and cis-9-octadecenoic acid (C18 : 1 ω9c). We propose two novel species within the genus Nocardia : Nocardia macrotermitis sp. nov. with the type strain RB20T (=VKM Ac-2841T=NRRL B65541T) and Nocardia aurantia sp. nov. with the type strain RB56T (=VKM Ac-2842T=NRRL B65542T).

Halophilic Actinomycete

A halophilic actinomycete strain, designated H55T, was isolated from Saharan soil sampled in the Mzab region (Ghardaïa, southern Algeria) and was characterized in a taxonomic study using a polyphasic approach. The cell wall was determined to contain meso-diaminopimelic acid and the characteristic whole-cell sugars were arabinose and galactose. The predominant menaquinones were found to be MK-10(H4) and MK-9(H4). The predominant cellular fatty acids were determined to be anteiso-C17 : 0, iso-C16 : 0 and iso-C15 : 0. The diagnostic phospholipid detected was phosphatidylcholine. The morphological and chemotaxonomic characteristics of the strain were consistent with those of members of the genus Actinopolyspora , and 16S rRNA gene sequence analysis confirmed that strain H55T was a member of this genus. DNA–DNA hybridization values between strain H55T and the type strains of the nearest species of the genus Actinopolyspora , Actinopolyspora erythraea and A. alba , were clearly below the 70 % threshold. The genotypic and phenotypic data showed that the organism represents a novel species of the genus Actinopolyspora , for which the name Actinopolyspora mzabensis sp. nov. is proposed, with the type strain H55T ( = DSM 45460T = CCUG 62965T).

A novel Gram-staining-positive, rod-shaped, motile, strictly aerobic, endospore-forming bacterium, designated WCC 4585T, was isolated from a pharmaceutical production line. The organism grew optimally at 30 °C, at pH 8 and in the presence of 0.5 % (w/v) NaCl. Oval endospores were formed subterminally and terminally in swollen sporangia. The cell-wall diamino acid was meso-diaminopimelic acid (type A1γ) and the genomic DNA G+C content was 38.7 mol%. The major menaquinone was MK-7. The cellular fatty acid profile contained major amounts of iso-C15 : 0, anteiso-C15 : 0 and anteiso-C17 : 0, and the cellular phospholipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and aminophospholipid. The isolate was most closely related to Bacillus oceanisediminis H2T, Bacillus infantis SMC 4352-1T, Bacillus firmus NCIMB 9366T, Bacillus circulans ATCC 4513T and Bacillus horneckiae DSM 23495T with which it shared less than 98.0 % 16S rRNA gene sequence similarity. DNA–DNA relatedness values between strain WCC 4585T and five type strains of related species were ≤27 % and sequence similarity values based on groEL sequences were ≤88.7 %. On the basis of the characteristics presented, strain WCC 4585T is proposed to represent a novel species, Bacillus gottheilii sp. nov. The type strain is WCC 4585T( = DSM 23668T = CCUG 59876T = LMG 25856T).

Physiological And Biochemical

A yellow-coloured bacterial strain, designated HB2T, isolated from stratum water was investigated using a polyphasic taxonomic approach. Cells were Gram-stain-negative, aerobic, non-spore-forming, non-flagellated and rod-shaped. Phylogenetic analysis based on 16S rRNA gene sequences showed that the strain was a member of the genus Luteimonas , its three closest neighbours being Luteimonas aquatica BCRC 17731T (97.5 % similarity), Luteimonas marina JCM 12488T (97.3 %) and Luteimonas aestuarii DSM 19680T (96.9 %). Strain HB2T could clearly be distinguished from these type strains based on phylogenetic analysis, DNA–DNA hybridization, fatty acid composition and a range of physiological and biochemical characteristics. It is evident from the genotypic and phenotypic data that strain HB2T represents a novel species of the genus Luteimonas , for which the name Luteimonas huabeiensis sp. nov. is proposed. The type strain is HB2T ( = DSM 26429T = CICC 11005sT).

Distinct Lineage

A Gram-stain-negative, non-spore-forming, strictly aerobic, orange-pigmented bacterial strain, motile by gliding, designated CAU 1044T, was isolated from a green seaweed and its taxonomic position was investigated using a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain CAU 1044T formed a distinct lineage within the genus Maribacter and was most closely related to Maribacter antarcticus JCM 15445T and Maribacter arcticus KOPRI 20941T (96.3 and 95.7 % similarity, respectively). Strain CAU 1044T contained menaquinone 6 as the only isoprenoid quinone and iso-C15 : 0, summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c and/or iso-C15 : 0 2-OH), iso-C17 : 0 3-OH and iso-C15 : 1 G as the major fatty acids. The cell wall peptidoglycan of strain CAU 1044T contained meso-diaminopimelic acid and the major whole-cell sugars were glucose and ribose. The polar lipids were composed of phosphatidylethanolamine, one unidentified phospholipid, six unidentified aminolipids and four unidentified lipids. The DNA G+C content was 40.2 mol%. On the basis of phenotypic data and phylogenetic inference, strain CAU 1044T should be classified as a representative of a novel species in the genus Maribacter for which the name Maribacter chungangensis sp. nov. is proposed. The type strain is CAU 1044T ( = KCTC 23735T  = CCUG 61948T). Emended descriptions of the genus Maribacter and the species M. arcticus KCTC 22053T are also proposed.

Taxonomic Approach

A bacterial strain, designated NSW-5T, was isolated from a water sample taken from Niao-Song Wetland Park in Taiwan and characterized using a polyphasic taxonomic approach. Cells of strain NSW-5T were strictly aerobic, Gram-stain-negative, non-motile and polymorphic, being straight, vibrioid, curved and spiral-shaped rods surrounded by a thick capsule and forming light pink-coloured colonies. Some rings consisting of several cells were present. Growth occurred at 10–40 °C (optimum, 25 °C), with 0–3.0 % NaCl (optimum, 0 %) and at pH 6.0–8.0 (optimum, pH 7.0). Phylogenetic analyses based on 16S rRNA gene sequences showed that strain NSW-5T belonged to the genus Arcicella with sequence similarities of 98.6, 98.0 and 97.3 % with Arcicella aquatica NO-502T, Arcicella rosea TW5T and Arcicella aurantiaca TNR-18T, respectively. The predominant cellular fatty acids were summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c; 20.8 %), C16 : 0 (14.6 %), iso-C15 : 0 (13.8 %), C16 : 1ω5c (12.5 %) and C18 : 0 (11.4 %), and the only respiratory quinone was MK-7. The polar lipid profile consisted of phosphatidylethanolamine and several uncharacterized glycolipids, aminolipids, phospholipids and aminophospholipids. The DNA G+C content of strain NSW-5T was 44.1 mol%. The DNA–DNA relatedness of strain NSW-5T with respect to recognized species of the genus Arcicella was less than 70 %. On the basis of phylogenetic inference and phenotypic data, strain NSW-5T should be classified as a representative of a novel species, for which the name Arcicella rigui sp. nov. is proposed. The type strain is NSW-5T ( = KCTC 23307T = BCRC 80260T). Emended descriptions of the genus Arcicella and of Arcicella aquatica , Arcicella rosea and Arcicella aurantiaca are also proposed.

Diamino Acid

A Gram-positive, non-spore-forming bacterium (GW-12028T) of unknown origin showing filamentous growth and producing spherical sporangia was studied for its taxonomic allocation. The 16S rRNA gene sequence analysis and subsequent similarity studies showed that strain GW-12028T belongs to the genus Streptosporangium , and is most closely related to Streptosporangium pseudovulgare DSM 43181T (99.9 %) and Streptosporangium nondiastaticum DSM 43848T (99.6 %) and more distantly related to Streptosporangium fragile IFO 14311T (98.4 %) and other species of the genus Streptosporangium (95.8 to 98 %). Chemotaxonomic analyses showed that the peptidoglycan diamino acid was meso-diaminopimelic acid. Whole-cell hydrolysates contained madurose as the diagnostic sugar and exhibited a quinone system that contained predominantly menaquinones with nine isoprenoic units in the side chain [MK-9, MK-9(H2), MK-9(H4)]. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylglycerol, phoshatidylethanolamine, hydroxyphosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol-mannosides, four unidentified glycolipids, a phospholipid and an aminolipid. The polyamine pattern contained the major compounds spermine and spermidine. The major fatty acids were 10-methyl C17 : 0, iso-C16 : 0 and C15 : 0. These chemotaxonomic traits are common to other species of the genus Streptosporangium . DNA–DNA hybridizations and physiological and biochemical tests in comparison with the type strains of the most closely related species, S. nondiastaticum and S. pseudovulgare , allowed genotypic and phenotypic differentiation of strain GW-12028T. This strain represents a novel species, for which we propose the name Streptosporangium sandarakinum sp. nov., with the type strain GW-12028T ( = LMG 27062T  = DSM 45763T).

‘Bacillus macroides’ ATCC 12905T ( = DSM 54T = LMG 18474T), isolated in 1947 from cow dung, was not included in the Approved Lists of Bacterial Names and so it lost standing in bacteriological nomenclature. Reinvestigation of the strain, including DNA–DNA relatedness experiments, revealed that ‘Bacillus macroides’ is genomically distinct from its closest relatives Lysinibacillus xylanilyticus , Lysinibacillus boronitolerans and Lysinibacillus fusiformis (as determined by 16S rRNA gene sequence analysis, with pairwise similarity values of 99.2, 98.8 and 98.5 %, respectively, with the type strains of these species). Further analysis showed that ‘Bacillus macroides’ shares the A4α l-Lys–d-Asp peptidoglycan type with other members of the genus Lysinibacillus and can thus be attributed to this genus. These results, combined with additional phenotypic data, justify the description of strain LMG 18474T ( = DSM 54T = ATCC 12905T) as Lysinibacillus macroides sp. nov., nom. rev.
