Phenotypic Properties

A Gram-positive, non-motile, endospore-forming bacterial strain, designated Gsoil 420T, was isolated from soil of a ginseng field in Pocheon Province, South Korea, and was characterized, using a polyphasic approach, in order to determine its taxonomic position. The novel isolate consisted of strictly aerobic, rod-shaped cells and was able to grow in medium supplemented with up to 12 % NaCl at 25 °C and pH 6.5–7.0. Comparative 16S rRNA gene sequence analysis showed that strain Gsoil 420T fell within the radiation of the cluster comprising Bacillus species and formed a coherent cluster with Bacillus niacini (16S rRNA gene sequence similarity, 98.6 %), Bacillus bataviensis (98.6 %), Bacillus soli (98.3 %), Bacillus drentensis (98.0 %), Bacillus novalis (98.0 %), Bacillus vireti (97.9 %), Bacillus foraminis (97.6 %), Bacillus fumarioli (97.4 %) and Bacillus jeotgali (97.0 %). The levels of 16S rRNA gene sequence similarity with respect to other Bacillus species with validly published names were less than 96.8 %. Strain Gsoil 420T had a genomic DNA G+C content of 44.9 mol% and the predominant respiratory quinone was MK-7. The major fatty acids were anteiso-C15 : 0 (33.9 %), iso-C15 : 0 (24.5 %) and iso-C14 : 0 (19.9 %). These chemotaxonomic results supported the affiliation of strain Gsoil 420T to the genus Bacillus. However, low DNA–DNA relatedness values and distinguishing phenotypic characteristics allowed genotypic and phenotypic differentiation of strain Gsoil 420T from recognized Bacillus species. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain Gsoil 420T represents a novel species of the genus Bacillus, for which the name Bacillus pocheonensis sp. nov. is proposed. The type strain is Gsoil 420T (=KCTC 13943T=DSM 18135T).

A Gram-staining-negative, yellow-coloured, strictly aerobic, non-spore-forming, rod-shaped bacterium, designated HS39T, isolated from a soil sample collected from a natural Populus euphratica forest in Xinjiang, China, was characterized using a polyphasic approach. The isolate grew optimally at 30–37 °C, at pH 6.5–8.0 and with 0–3 % NaCl. Analysis of the 16S rRNA gene sequence of strain HS39T revealed that it is a member of the genus Sphingobacterium. Sphingobacterium mizutaii ATCC 33299T was the nearest relative (94.0 % 16S rRNA gene sequence similarity). The G+C content of the genomic DNA was 40.2 mol%. The major fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH and summed feature 3 (comprising C16 : 1 ω6c and/or C16 : 1 ω7c). The predominant isoprenoid quinone was MK-7. On the basis of phenotypic properties and phylogenetic inference, strain HS39T represents a novel species of the genus Sphingobacterium, for which the name Sphingobacterium shayense sp. nov. is proposed. The type strain is HS39T (=CCTCC AB 209006T =NRRL B-59203T).

The 16S Rrna Gene

A Gram-negative, strictly aerobic bacterium, designated CL-ES53T, was isolated from surface water of the East Sea in Korea. Cells of strain CL-ES53T were short rods and motile by means of monopolar flagella. Strain CL-ES53T grew with 4–21 % NaCl (optimum 10 %) and at 5–40 °C (optimum 25 °C) and pH 5.2–8.8 (optimum pH 6.3–7.2). The major isoprenoid quinone was Q-8. The major fatty acids were C18 : 1 ω7c (42.0 %), C18 : 1 ω9c (14.8 %) and C14 : 0 (9.4 %). The genomic DNA G+C content was 64.9 mol%. Analysis of the 16S rRNA gene sequence of strain CL-ES53T revealed that it was a member of the genus Salinisphaera and most closely related to Salinisphaera shabanensis E1L3A T (96.9 % sequence similarity) and Salinisphaera hydrothermalis EPR70T (93.8 %). Phylogenetic analyses based on the 16S rRNA gene sequence showed that strain CL-ES53T formed a robust cluster with S. shabanensis E1L3A T. Although the 16S rRNA gene sequence similarity between strain CL-ES53T and S. shabanensis E1L3A T was rather high (96.9 %), DNA–DNA relatedness between these strains was 12 %, suggesting that they represent genomically distinct species. Strain CL-ES53T was differentiated from S. shabanensis E1L3A T and S. hydrothermalis EPR70T on the basis of optimum temperature for growth and certain phenotypic characteristics. The phylogenetic analysis and physiological and chemotaxonomic data show that strain CL-ES53T should be classified in the genus Salinisphaera within a novel species, for which the name Salinisphaera dokdonensis sp. nov. is proposed. The type strain is CL-ES53T (=KCCM 90064T =DSM 19549T).

A Gram-positive, strictly aerobic, rod-shaped, non-motile bacterial strain, designated MJ28T, was isolated from a sludge sample from the Daejeon sewage disposal plant in South Korea. A polyphasic approach was applied to study the taxonomic position of strain MJ28T. Strain MJ28T showed highest 16S rRNA gene sequence similarity to Pseudoclavibacter soli KP02T (95.2 %). Levels of 16S rRNA gene sequence similarity to the type strains of other Pseudoclavibacter species were less than 94.0 %. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain MJ28T belonged to the clade formed by members of the genus Pseudoclavibacter in the family Microbacteriaceae. The G+C content of the genomic DNA of strain MJ28T was 65.8 mol%. The chemotaxonomic characteristics of strain MJ28T showed features typical of the genus Pseudoclavibacter, with MK-9 as the predominant respiratory quinone, 2,4-diaminobutryic acid as the diamino acid in the peptidoglycan, and anteiso-C17 : 0 (44.6 %), anteiso-C15 : 0 (35.7 %) and C16 : 0 (9.5 %) as the major fatty acids. On the basis of phylogenetic inference, fatty acid profile and other phenotypic properties, strain MJ28T is considered to represent a novel species of the genus Pseudoclavibacter, for which the name Pseudoclavibacter caeni sp. nov. is proposed. The type strain is MJ28T ( = KCTC 19773T = JCM 16921T).

Control Activity

Three Gram-negative, yellow-pigmented strains were isolated from the rhizospheres of Spathiphyllum plants grown in a compost-amended potting mix. The strains showed biological control activity towards the root-rot plant pathogen Cylindrocladium spathiphylli, and were characterized to determine their taxonomic position. Cells of the strains were non-motile rods, and the strains were oxidase- and catalase-positive and unable to ferment most sugars tested. The three strains showed differences in growth temperature range, optimal growth temperature and some biochemical reactions. The majority of the fatty acids were branched, and large amounts of 15 : 0 iso and 17 : 1 iso ω9c were present. The 16S rRNA gene sequence (1497 bp) of strain B39T showed the highest level of similarity (98.5 %) to that of Rhodanobacter fulvus IAM 15025T, followed by Rhodanobacter lindaniclasticus LMG 18385T (96.0 %; strain no longer extant), Dyella koreensis CCUG 50883T (96.4 %), Dyella japonica DSM 16301T (96.3 %), Frateuria aurantia LMG 1558T (96.2 %) and Fulvimonas soli LMG 19981T (95.9 %). Less than 90 % 16S rRNA gene sequence similarity was observed for other members of the Gammaproteobacteria. The mean DNA–DNA reassociation value for the three strains was 100 % and was 25 % when the strains were compared with DNA from R. fulvus LMG 23003T. The strains had a mean DNA G+C content of 67.6 mol%. On the basis of their phylogenetic, genomic and phenotypic properties, the three strains represent a novel species within the genus Rhodanobacter, for which the name Rhodanobacter spathiphylli sp. nov. is proposed. The type strain is strain B39T (=LMG 23181T=DSM 17631T).

The taxonomic position of a rhizosphere soil isolate, designated strain SR8.15T, was determined by using a polyphasic approach. Phylogenetic analysis based on an almost-complete 16S rRNA gene sequence of the strain showed that it formed a well-separated sub-branch within the radiation encompassing the genus Saccharopolyspora. Highest levels of 16S rRNA gene sequence similarity were found between strain SR8.15T and Saccharopolyspora shandongensis CGMCC 4.3530T (98.9 %) and Saccharopolyspora spinosa DSM 44228T (98.5 %). However, these strains shared low levels of DNA–DNA relatedness (<26 %). Strain SR8.15T had chemical characteristics consistent with its classification in the genus Saccharopolyspora. It contained meso-diaminopimelic acid as the diagnostic diamino acid. Whole-cell hydrolysates contained arabinose and galactose. The diagnostic phospholipids were phosphatidylcholine, phosphatidylglycerol and phosphatidylinositol. The main menaquinone was MK-9(H4). No mycolic acid was detected. The predominant cellular fatty acid was iso-C16 : 0. The G+C content of the genomic DNA of strain SR8.15T was 70.3 mol%. Strain SR8.15T had a phenotypic profile that readily distinguished it from recognized representatives of the genus Saccharopolyspora. It is evident from its combined genotypic and phenotypic properties that strain SR8.15T represents a novel species of the genus Saccharopolyspora, for which the name Saccharopolyspora phatthalungensis sp. nov. is proposed. The type strain is SR8.15T (=TISTR 1921T=BCC 35844T=NRRL B-24798T).

A Gram-staining-negative, motile, agarolytic bacterium, designated M-M1T, was isolated from marine sand obtained from Geoje Island, South Sea, Korea, and its taxonomic position was investigated using a polyphasic taxonomic approach. Strain M-M1T grew optimally at pH 7.0–8.0, at 30 °C and in the presence of 2 % (w/v) NaCl. It did not grow in the presence of >7 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain M-M1T fell within the clade comprising members of the genus Thalassomonas, clustering with Thalassomonas agarivorans TMA1T, Thalassomonas loyana CBMAI 722T and Thalassomonas ganghwensis JC2041T, with which it exhibited 16S rRNA gene sequence similarity values of 96.4, 96.0 and 94.9 % respectively. Strain M-M1T exhibited 94.7–95.2 % 16S rRNA gene sequence similarity to the other species of the genus Thalassomonas. Strain M-M1T contained Q-8 as the predominant ubiquinone and C16 : 1ω7c and/or iso-C15 : 0 2-OH, C16 : 0 and C18 : 1ω7c as the major fatty acids. The DNA G+C content was 44.2 mol%. Strain M-M1T could be differentiated from phylogenetically related species of the genus Thalassomonas by differences in some phenotypic properties. On the basis of the phenotypic, chemotaxonomic and phylogenetic data, strain M-M1T is considered to represent a novel species of the genus Thalassomonas, for which the name Thalassomonas agariperforans sp. nov. is proposed. The type strain is M-M1T ( = KCTC 23343T  = CCUG 60020T).

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).

Five strains of strictly aerobic, heterotrophic bacteria that form pink–red colonies and are capable of hydrolysing pectin, xylan, laminarin, lichenan and starch were isolated from acidic Sphagnum peat bogs and were designated OB1010T, LCBR1, TPB6011T, TPB6028T and TPO1014T. Cells of these isolates were Gram-negative, non-motile rods that produced an amorphous extracellular polysaccharide-like substance. Old cultures contained spherical bodies of varying sizes, which represent starvation forms. Cells of all five strains were acidophilic and psychrotolerant, capable of growth at pH 3.0–7.5 (optimum pH 3.8–4.5) and at 2–33 °C (optimum 15–22 °C). The major fatty acids were iso-C15 : 0, C16 : 0 and summed feature 3 (C16 : 1 ω7c and/or iso-C15 : 0 2-OH). The major menaquinone detected was MK-8. The pigments were carotenoids. The genomic DNA G+C contents were 57.3–59.3 mol%. The five isolates were found to be members of subdivision 1 of the phylum Acidobacteria and displayed 95.3–98.9 % 16S rRNA gene sequence similarity to each other. The closest described relatives to strains OB1010T, LCBR1, TPB6011T, TPB6028T, and TPO1014T were members of the genera Terriglobus (94.6–95.8 % 16S rRNA gene sequence similarity) and Edaphobacter (94.2–95.4 %). Based on differences in cell morphology, phenotypic characteristics and hydrolytic capabilities, we propose a novel genus, Granulicella gen. nov., containing four novel species, Granulicella paludicola sp. nov. with type strain OB1010T (=DSM 22464T =LMG 25275T) and strain LCBR1, Granulicella pectinivorans sp. nov. with type strain TPB6011T (=VKM B-2509T =DSM 21001T), Granulicella rosea sp. nov. with type strain TPO1014T (=DSM 18704T =ATCC BAA-1396T) and Granulicella aggregans sp. nov. with type strain TPB6028T (=LMG 25274T =VKM B-2571T).

A novel, anaerobic, chemo-organotrophic bacterium, designated strain Ra1766HT, was isolated from sediments of the Guaymas basin (Gulf of California, Mexico) taken from a depth of 2002 m. Cells were thin, motile, Gram-stain-positive, flexible rods forming terminal endospores. Strain Ra1766HT grew at temperatures of 25–45 °C (optimum 30 °C), pH 6.7–8.1 (optimum 7.5) and in a salinity of 5–60 g l− 1 NaCl (optimum 30 g l− 1). It was an obligate heterotrophic bacterium fermenting carbohydrates (glucose and mannose) and organic acids (pyruvate and succinate). Casamino acids and amino acids (glutamate, aspartate and glycine) were also fermented. The main end products from glucose fermentation were acetate, butyrate, ethanol, H2 and CO2. Sulfate, sulfite, thiosulfate, elemental sulfur, fumarate, nitrate, nitrite and Fe(III) were not used as terminal electron acceptors. The predominant cellular fatty acids were C14  : 0, C16 : 1ω7, C16 : 1ω7 DMA and C16 : 0. The main polar lipids consisted of phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine and phospholipids. The G+C content of the genomic DNA was 33.7 mol%. Phylogenetic analysis of the 16S rRNA gene sequence indicated that strain Ra1766HT was affiliated to cluster XI of the order Clostridiales, phylum Firmicutes. The closest phylogenetic relative of Ra1766HT was Geosporobacter subterraneus (94.2 % 16S rRNA gene sequence similarity). On the basis of phylogenetic inference and phenotypic properties, strain Ra1766HT ( = DSM 27501T = JCM 19377T) is proposed to be the type strain of a novel species of a novel genus, named Crassaminicella profunda.

A Gram-stain-negative, yellow-pigmented, rod-shaped, strictly aerobic, non-flagellated, non-gliding and oxidase- and catalase-positive bacterium, designated A6T, was isolated from a marine sponge, Halichondria oshoro, collected on the coast of Jeju Island, South Korea. Phylogenetic analysis based on the nearly complete 16S rRNA gene sequence revealed that strain A6T was a member of the family Flavobacteriaceae. The closest relatives were Aquimarina intermedia LMG 23204T, A. latercula ATCC 23177T, A. brevivitae SMK-19T and A. muelleri KMM 6020T, with which strain A6T shared 95.7, 95.1, 94.7 and 94.6 % 16S rRNA gene sequence similarity, respectively. The dominant fatty acids of strain A6T were iso-C15 : 0 (32.2 %), iso-C17 : 0 3-OH (20.0 %), iso-C15 : 0 3-OH (12.3 %), iso-C15 : 1 G (7.2 %) and summed feature 3 (comprising iso-C15 : 0 2-OH and/or C16 : 1 ω7c; 6.8 %). The DNA G+C content of strain A6T was 36.0 mol% and the major respiratory quinone was MK-6. On the basis of combined phenotypic and phylogenetic analyses, strain A6T represents a novel species of the genus Aquimarina, for which the name Aquimarina spongiae sp. nov. is proposed. The type strain is A6T (=KCTC 22663T =DSM 22623T).
