Black Sand

A Gram-positive, rod-shaped, yellow-pigmented actinomycete, designated strain SBS-26T, was isolated from a sample of black sand from Samyang Beach on Jeju Island (Republic of Korea) and was subjected to polyphasic characterization to unravel its taxonomic status. Phylogenetic analyses based on 16S rRNA gene sequences revealed that the organism belongs to the genus Nocardioides but forms a distinct branch at the base of a Nocardioides ganghwensis–Nocardioides oleivorans cluster. The 16S rRNA gene sequence of strain SBS-26T showed the highest levels of similarity to those of N. ganghwensis JC2055T (97.7 %) and N. oleivorans DSM 16090T (97.6 %). The levels of 16S rRNA gene sequence similarity between strain SBS-26T and other members of the genera Nocardioides and Marmoricola were in the range 93.0–96.2 %. The following chemotaxonomic characteristics support the phylogenetic association of strain SBS-26T with members of the genus Nocardioides: ll-diaminopimelic acid as the principal diamino acid of the peptidoglycan, MK-8(H4) as the major menaquinone, iso-C16 : 0 as the predominant fatty acid and a DNA G+C content of 69.1 mol%. The polar lipids contained phosphatidylcholine, phosphatidylglycerol, phosphatidylinositol and an unknown phospholipid. On the basis of the phenotypic, chemotaxonomic and phylogenetic data, strain SBS-26T represents a novel species of the genus Nocardioides, for which the name Nocardioides furvisabuli sp. nov. is proposed. The type strain is strain SBS-26T (=JCM 13813T=NRRL B-24465T).

Phenotypic Properties

A Gram-positive, non-motile and rod- or coccoid-shaped bacterial strain, MDN22T, was isolated from a soil sample from Korea. Strain MDN22T grew optimally at pH 7.0–8.0, at 30 °C and in the presence of 0–0.5 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain MDN22T was phylogenetically most closely related to the genera Nocardioides and Marmoricola. In the neighbour-joining phylogenetic tree, strain MDN22T was most closely related to Nocardioides jensenii KCTC 9134T, with which it exhibited 98.3 % 16S rRNA gene sequence similarity. The strain exhibited 93.1–96.9 % and 95.3–95.9 % 16S rRNA gene sequence similarities to the type strains of other species of the genera Nocardioides and Marmoricola, respectively. The chemotaxonomic properties of strain MDN22T were consistent with those of the genus Nocardioides; the cell-wall peptidoglycan type was based on ll-2,6-diaminopimelic acid, the predominant menaquinone was MK-8(H4) and the major fatty acids were iso-C16 : 0 and C17 : 1. The DNA G+C content was 68.7 mol%. DNA–DNA relatedness data and differential phenotypic properties suggested that strain MDN22T could be differentiated from N. jensenii and Nocardioides dubius. On the basis of the data obtained, strain MDN22T is considered to represent a novel species of the genus Nocardioides, for which the name Nocardioides daedukensis sp. nov., is proposed. The type strain is MDN22T (=KCTC 19601T=CCUG 57505T).

Phenotypic Data

A novel Gram-stain-positive, aerobic, motile, non-spore-forming coccus-shaped actinomycete, designated strain YIM 121300T, was isolated from alkaline sediment in Yuanjiang, Yunnan province, south-west China. Phylogenetic analyses based on the 16S rRNA gene sequence showed that strain YIM 121300T was affiliated to the genus Kineococcus, and was closely related to Kineococcus aurantiacus IFO 15268T (97.3 % similarity). 16S rRNA gene sequence similarity to other species of the genus Kineococcus was < 97 %. The cell wall contained meso-diaminopimelic acid as the diagnostic diamino acid. The whole-cell sugars contained arabinose, galactose, glucose, mannose and ribose. The predominant menaquinone was MK-9(H2). Mycolic acids were not detected. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside and an unknown phospholipid. The predominant fatty acids were anteiso-C15 : 0 and anteiso-C15 : 1 A. The G+C content of the genomic DNA was 75.1 mol%. DNA–DNA relatedness (55 ± 4 % to K. aurantiacus IFO 15268T) and differential phenotypic data demonstrated that strain YIM 121300T was distinguished from all related species of the genus Kineococcus. On the basis of data from the present polyphasic study, the organism should be assigned to a novel species of the genus Kineococcus, for which the name Kineococcus gypseus sp. nov. is proposed. The type strain is YIM 121300T ( = CCTCC AA 2013232T = DSM 27627T).

Emended Description

A polyphasic taxonomic study was performed on 22 thermotolerant, aerobic, endospore-forming bacteria from dairy environments. Seventeen isolates were retrieved from raw milk, one from a filter cloth and four from grass, straw or milking equipment. These latter four isolates (R-6546, R-7499, R-7764 and R-7440) were identified as Bacillus thermoamylovorans based on DNA–DNA hybridizations (values above 70 % with Bacillus thermoamylovorans LMG 18084T) but showed discrepancies in characteristics with the original species description, so an emended description of this species is given. According to 16S rRNA gene sequence analysis and DNA–DNA hybridization experiments, the remaining 18 isolates (R-6488T, R-28193, R-6491, R-6492, R-7336, R-33367, R-6486, R-6770, R-31288, R-28160, R-26358, R-7632, R-26955, R-26950, R-33520, R-6484, R-26954 and R-7165) represented one single species, most closely related to Bacillus thermoamylovorans (93.9 % 16S rRNA gene sequence similarity), for which the name Bacillus thermolactis is proposed. Cells were Gram-stain-positive, facultatively anaerobic, endospore-forming rods that grew optimally at 40–50 °C. The cell wall peptidoglycan type of strain R-6488T, the proposed type strain, was A1γ based on meso-diaminopimelic acid. Major fatty acids of the strains were C16 : 0 (28.0 %), iso-C16 : 0 (12.1 %) and iso-C15 : 0 (12.0 %). MK-7 was the predominant menaquinone, and major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and some unidentified phospholipids. DNA G+C content was 35.0 mol%. Phenotypic properties allowed discrimination from other thermotolerant species of the genus Bacillus and supported the description of the novel species Bacillus thermolactis, with strain R-6488T ( = LMG 25569T  = DSM 23332T) as the proposed type strain.

Two Gram-stain-positive, rod-shaped and endospore-forming bacteria, designated WM-1T and WM-4, were isolated from a paddy soil and a forest soil, respectively, in South China. Comparative 16S rRNA gene sequence analyses showed that both strains were members of the genus Oceanobacillus and most closely related to Oceanobacillus chironomi LMG 23627T with pairwise sequence similarity of 96.0 %. The isolates contained menaquinone-7 (MK-7) as the respiratory quinone and anteiso-C15 : 0, anteiso-C17 : 0 and iso-C15 : 0 as the major fatty acids (>10 %). Polar lipids consisted of a predominance of diphosphatidylglycerol and moderate to minor amounts of phosphatidylglycerol and phosphatidylinositol. The cell-wall peptidoglycan contained meso-diaminopimelic acid. The DNA G+C content was 38.6–39.2 mol%. The 16S rRNA gene sequence of strain WM-1T displayed 99.7 % similarity to that of strain WM-4, and DNA–DNA hybridization between the two strains showed a relatedness value of 91 %. Based on the results of this polyphasic study, strains WM-1T and WM-4 represent a novel species in the genus Oceanobacillus , for which the name Oceanobacillus luteolus sp. nov. is proposed. The type strain is WM-1T ( = KCTC 33119T = CGMCC 1.12406T).

A Gram-stain-positive, non-spore-forming bacterium (GW5-5797T) was isolated on soil extract agar from sand collected at a depth of 5 m in the Caribbean Sea near Grenada. 16S rRNA gene sequence analysis and similarity studies showed that strain GW5-5797T belongs to the genus Nocardia, and is most closely related to Nocardia speluncae N2-11T (99.2 % similarity) and Nocardia jinanensis 04-5195T (99.2 %) and more distantly related to Nocardia rhamnosiphila 202GMOT (98.6 %) and other Nocardia species. Strain GW5-5797T could be distinguished from all other recognized Nocardia species by sequence similarity values less than 98.5 %. The peptidoglycan diamino acid was meso-diaminopimelic acid. Strain GW5-5797T exhibited a quinone system with the predominant compounds MK-8(H4ω-cyclo) and MK-8(H2). The polar lipid profile of GW5-5797T consisted of the major compounds diphosphatidylglycerol, phosphatidylethanolamine and an unidentified glycolipid, moderate amounts of phosphatidylinositol and a phosphatidylinositol mannoside and minor amounts of several lipids including a second phosphatidylinositol mannoside. The polyamine pattern contained the major compound spermine and moderate amounts of spermidine. The major fatty acids were C16 : 0, C18 : 1ω9c and 10-methyl C18 : 0. These chemotaxonomic traits are in excellent agreement with those of other Nocardia species. The results of DNA–DNA hybridizations and physiological and biochemical tests allowed genotypic and phenotypic differentiation of strain GW5-5797T from the most closely related species, showing 16S rRNA gene sequence similarities >98.5 %. Strain GW5-5797T therefore merits separate species status, and we propose the name Nocardia grenadensis sp. nov., with the type strain GW5-5797T ( = CCUG 60970T  = CIP 110294T).

A Gram-staining-positive bacterium, designated AS-0823T, which formed spiral spore chains on the aerial mycelium, was isolated from the intestinal tract of Armadillidium vulgare, a small terrestrial crustacean commonly found on the ground around houses in Japan. 16S rRNA gene sequence analysis showed that the isolate belonged to the genus Streptomyces and was most closely related to Streptomyces longisporus ISP 5166T (98.6 % 16S rRNA gene sequence similarity), Streptomyces curacoi NBRC 12761T (98.4 %) and Streptomyces griseoruber NBRC 12873T (98.4 %). The affiliation of strain AS-0823T to the genus Streptomyces was supported by chemotaxonomic data: iso-C16 : 0, anteiso-C15 : 0, C16 : 0, iso-C15 : 0 and anteiso-C17 : 0 as the major cellular fatty acids, ll-diaminopimelic acid as the characteristic diamino acid in the peptidoglycan and the absence of mycolic acids. DNA–DNA hybridization and physiological and biochemical analysis supported the differentiation of strain AS-0823T from S. longisporus JCM 4395T. Therefore, strain AS-0823T represents a novel species, for which the name Streptomyces coacervatus sp. nov. is proposed. The type strain is AS-0823T ( = IFM 11055T  = DSM 41983T  = JCM 17138T).

A nitrogen-fixing bacterium, designated strain Be17T, was isolated from rhizosphere soil of Begonia semperflorens planted in Beijing Botanical Garden, PR China. Phylogenetic analyses based on a segment of the nifH gene sequence and a full-length 16S rRNA gene sequence revealed that strain Be17T was a member of the genus Paenibacillus. High levels of 16S rRNA gene sequence similarity were found between strain Be17T and Paenibacillus graminis RSA19T (97.9 %), Paenibacillus sonchi LMG 24727T (97.8 %), Paenibacillus riograndensis CECT 7330T (96.2 %) and Paenibacillus borealis DSM 13188T (96.1 %), respectively. Levels of 16S rRNA gene sequence similarity between strain Be17T and the type strains of other recognized members of the genus Paenibacillus were below 96.0 %. However, the DNA–DNA hybridization values between strain Be17T and P. graminis RSA19T, P. sonchi LMG 24727T and P. riograndensis CECT 7330T were 47.9 %, 38.7 % and 37.5 %, respectively. The DNA G+C content of strain Be17T was 52.9 mol%. The major fatty acid component of strain Be17T was anteiso-branched C15 : 0 (30.92 %). The major isoprenoid quinone was MK-7.
