A Gram-stain-positive, oxidase- and catalase-positive, motile, aerobic, and rod-shaped bacterial strain, designated as DCT-5T, was isolated from a native plant belonging to the genus Campanula at Dokdo island, Republic of Korea. Growth of the strain DCT-5T was observed at 15–37°C (optimum 30°C) on R2A broth, pH 6.0–8.0 (optimum 7.0), and 0–5% (w/v) NaCl concentration (optimum 0%). The 16S rRNA gene sequence analysis revealed that strain DCT-5T was most closely related to Arthrobacter silviterrae KIS14-16T, Arthrobacter livingstonensis LI2T, Arthrobacter stackebrandtii CCM 2783T, Arthrobacter cryoconiti Cr6-08T, Arthrobacter ramosus CCM 1646T, and Arthrobacter psychrochitiniphilus GP3T with pairwise sequence similarities of 98.76%, 97.47%, 97.25%, 97.11%, 97.11%, and 97.00%, respectively. The DNA G+C content of strain DCT-5T was 64.7 mol%, and its DNA–DNA relatedness values with A. silviterrae KIS14-16T, A. livingstonensis LI2T, A. stackebrandtii CCM 2783T, A. psychrochitiniphilus GP3T, A. ramosus CCM 1646T, and A. cryoconiti Cr6-08T were 32.57 ± 2.02%, 28.75 ± 0.88%, 31.93 ± 1.15%, 34.73 ± 1.86%, 29.12 ± 1.56%, and 27.23 ± 0.88%, respectively. The major quinone was MK-9(H2) and major fatty acids were anteiso-C15:0, anteiso-C17:0, iso-C15:0, and iso-C16:0. The polar lipids were diphosphatidylglycerol (DPG), phosphatidylglycerol (PG), phosphatidylinositol (PI), unidentified glycolipid (GL), two unidentified aminophospholipids (APLs), and three unidentified lipids (Ls). The peptidoglycan type was A3α. On the basis of phenotypic, phylogenetic, genotypic, and chemotaxonomic characteristics, strain DCT-5T represents a novel species of the genus Arthrobacter, for which the name Arthrobacter dokdonellae sp. nov. is proposed. The type strain is DCT-5T (= KCTC 49189T = LMG 31284T).

Abstract

The novel Gram-stain-negative, rod-shaped, aerobic bacterial strain DCR-13T was isolated from a native plant belonging to the genus Campanula on Dokdo, an island in the Republic of Korea. Comparative analysis of the 16S rRNA gene sequence indicated that this strain is closely related to Paraburkholderia peleae PP52-1T (98.43% 16S rRNA gene sequence similarity), Paraburkholderia oxyphila NBRC 105797T (98.42%), Paraburkholderia sacchari IPT 101T (98.28%), Paraburkholderia mimosarum NBRC 106338T (97.80%), Paraburkholderia denitrificans KIS30-44T (97.46%), and Paraburkholderia paradise WAT (97.45%). This analysis of the 16S rRNA gene sequence also suggested that DCR-13T and the six closely related strains formed a clade within the genus Paraburkholderia, but that DCR-13T was clearly separated from the established species. DCR-13T had ubiquinone 8 as its predominant respiratory quinone, and its genomic DNA G + C content was 63.9 mol%. The isolated strain grew at a pH of 6.0–8.0 (with an optimal pH of 6.5), 0–4% w/v NaCl (with an optimal level of 0%), and a temperature of 18–42°C (with an optimal temperature of 30°C). The predominant fatty acids were C16:0, summed feature 8 (C18:1 ω7c/C18:1 ω6c), C17:0 cyclo, C19:0 cyclo ω8c, summed feature 3 (C16:1 ω6c/C16:1 ω7c) and summed feature 2 (C12:0 aldehyde), and the major polar lipids were phosphatidylglycerol and phosphatidylethanolamine. On the basis of polyphasic evidence, it is proposed that strain DCR-13T (= KCTC 62811T = LMG 30889T) represents the type strain of a novel species, Paraburkholderia dokdonella sp. nov.

Abstract

Strain DCT-19T, representing a Gram-stain-positive, rodshaped, aerobic bacterium, was isolated from a native plant belonging to the genus Campanula on Dokdo, the Republic of Korea. Comparative analysis of the 16S rRNA gene sequence showed that this strain was closely related to Paenibacillus amylolyticus NRRL NRS-290T (98.6%, 16S rRNA gene sequence similarity), Paenibacillus tundrae A10bT (98.1%), and Paenibacillus xylanexedens NRRL B-51090T (97.6%). DNADNA hybridization indicated that this strain had relatively low levels of DNA-DNA relatedness with P. amylolyticus NRRL NRS-290T (30.0%), P. xylanexedens NRRL B-51090T (29.0%), and P. tundrae A10bT (24.5%). Additionally, the genomic DNA G + C content of DCT-19T was 44.8%. The isolated strain grew at pH 6.0–8.0 (optimum, pH 7.0), 0–4% (w/v) NaCl (optimum, 0%), and a temperature of 15–45°C (optimum 25–30°C). The sole respiratory quinone in the strain was menaquinone-7, and the predominant fatty acids were C15:0 anteiso, C16:0 iso, and C16:0. In addition, the major polar lipids were diphosphatidylglycerol and phosphatidylethanolamine. Based on its phenotypic properties, genotypic distinctiveness, and chemotaxonomic features, strain DCT-19T is proposed as a novel species in the genus Paenibacillus, for which the name Paenibacillus seodonensis sp. nov. is proposed (=KCTC 43009T =LMG 30888T). The type strain of Paenibacillus seodonensis is DCT-19T.

Abstract

Flavobacteriaceae, are typically isolated from marine environments. Polaribacter dokdonensis DSW-5, the type strain of the species, is a Gram-negative bacterium isolated from the East Sea of Korea. Whole genome shotgun sequencing was performed with the HiSeq 2000 platform and paired-end reads were generated at 188-fold coverage. The sequencing reads were assembled into two contigs with a total length of 3.08 Mb. The genome sequences of DSW-5 contain 2,776 proteincoding sequences and 41 RNA genes. Comparison of average nucleotide identities among six available Polaribacteria genomes including DSW-5 suggested that the DSW-5 genome is most similar to that of Polaribacter sp. MED152, which is a proteorhodopsin-containing marine bacterium. A phylogenomic analysis of the six Polaribacter strains and 245 Flavobacteriaceae bacteria confirmed a close relationship of the genus Polaribacter with Tenacibaculum and Kordia. DSW-5’s genome has a gene encoding proteorhodopsin and genes encoding 85 enzymes belonging to carbohydrate-active enzyme families and involved in polysaccharide degradation, which may play important roles in energy metabolism of the bacterium in the marine ecosystem. With genes for 238 CAZymes and 203 peptidases, DSW-5 has a relatively high number of degrading enzymes for its genome size suggesting its characteristics as a free-living marine heterotroph.

Abstract

A Gram-stain-positive, motile, endospore-forming, and strictly aerobic rod-shaped bacterium designated DS80T was isolated from an island soil. The strain DS80T grew at temperatures between 15 and 40°C (optimum = 30°C) and at pH values ranging from 5.0 to 9.0 (optimum = 7.0). The phylogenetic analysis based on the comparisons of the 16S rRNA gene sequences showed that the isolate was affiliated to the genus Paenibacillus and was mostly related to Paenibacillus assamensis GPTSA11T (with the sequence similarity of 96.33%) and Paenibacillus urinalis 5402403T(95.48%). The G+C content of the genomic DNA was 44.0 mol% and the major fatty acids were anteiso-C15:0, iso-C15:0, iso-C16:0, and C16:1 ω11c. Strain DS80T contained MK-7 as the major menaquinone, and phosphatidylglycerol, phosphatidylethanolamine, and diphosphatidylglycerol as the major polar lipids. The peptidoglycan contained a major amount of meso-diaminopimelic acid. The chemotaxonomic profile of strain DS80T was consistent with that of Paenibacillus. However, the phenotypic properties clearly separated the strain from other species of the genus. Accordingly, a new species, Paenibacillus insulae sp. nov., is proposed (type strain =DS80T =JCM 17278T =KCTC 13833T).

Abstract

A novel facultatively anaerobic strain DH1T was isolated from deep sub-seafloor sediment at a depth of 900 m below the seafloor off Seo-do (the west part of Dokdo Island) in the East Sea of the Republic of Korea. The new strain was characterized using polyphasic approaches. The isolate was Gram-stain-negative, motile by gliding, non-spore-forming rods, oxidase-negative, and catalase-positive; and formed colonies of orange-red color. The NaCl range for growth was 0.5–7.0% (w/v) and no growth was observed in the absence of NaCl. The isolate grew optimally at 30°C, with 2% (w/v) NaCl and at pH 7. The cell-wall hydrolysates contained ribose as a major sugar. The DNA G+C content was 40.8 mol%. The closest related strains are Sunxiuqinia faeciviva JAM-BA0302T and Sunxiuqinia elliptica DQHS-4T (97.9 and 96.3% sequence similarity, respectively). The level of DNADNA relatedness between strain DH1T and S. faeciviva JAMBA0302T was around 41% (but only 6% between DH1T and S. elliptica DQHS-4T). The major cellular fatty acids of the isolate were contained iso-C15:0 (25.9%), anteiso-C15:0 (16.7%), and summed feature 9 (comprising C16:0 3-OH and/or unknown fatty acid of dimethylacetal ECL 17.157; 13.2%). The predominant menaquinone was MK-7. On the basis of polyphasic evidence from this study, the isolate was considered to represent a novel species of the genus Sunxiuqinia, for which the name Sunxiuqinia dokdonensis sp. nov. is proposed; the type strain is DH1T (=KCTC 32503T =CGMCC 1.12676T =JCM 19380T).

Abstract: Plant growth promoting rhizobacteria Ochrobactrum lupini KUDC1013 and Novosphingobium pentaromativorans KUDC1065 isolated from Dokdo Island, S. Korea are capable of eliciting induced systemic resistance (ISR) in pepper against bacterial spot disease. The present study aimed to determine whether plant growth-promoting rhizobacteria (PGPR) strains including strain KUDC1013, strain KUDC1065, and Paenibacillus polymyxa E681 either singly or in combinations were evaluated to have the capacity for potential biological control and plant growth promotion effect in the field trials. Under greenhouse conditions, the induced systemic resistance (ISR) effect of treatment with strains KUDC1013 and KUDC1065 differed according to pepper growth stages. Drenching of 3-week-old pepper seedlings with the KUDC-1013 strain significantly reduced the disease symptoms. In contrast, treatment with the KUDC1065 strain significantly protected 5-week-old pepper seedlings. Under field conditions, peppers treated with PGPR mixtures containing E681 and KUDC1013, either in a two-way combination, were showed greater effect on plant growth than those treated with an individual treatment. Collectively, the application of mixtures of PGPR strains on pepper might be considered as a potential biological control under greenhouse and field conditions.
