Two actinobacterial isolates, strains SG15(T) and SGB14(T), were recovered through a microbial diversity study of nitrogen fixing nodules from Pisum sativum plants collected in Salamanca (Spain). The taxonomic status of these isolates was determined using a polyphasic approach and both presented chemotaxonomic and morphological properties consistent with their classification in the genus Micromonospora. For strains SG15(T) and SGB14(T), the highest 16S rRNA gene sequence similarities were observed with Micromonospora coxensis JCM 13248(T) (99...

A Gram-stain-negative, aerobic, non-motile, non-spore-forming bacterial strain, designated JDTF-31(T), was isolated from a tidal flat in Jindo, a South Korean island. Strain JDTF-31(T) grew optimally at 25 °C and in the presence of 2.0 % (w/v) NaCl. The neighbour-joining phylogenetic tree based on 16S rRNA gene sequences revealed that strain JDTF-31(T) fell within the cluster comprising the type strains of Tenacibaculum species, joining the type strain of Tenacibaculum soleae. The novel strain exhibited 16S rRNA gene sequence similarity values of 98...

A novel halophilic bacterium, strain GSS13(T), capable of growing at salinities of 8-28 % (w/v) NaCl (optimally at 24 %, w/v) was isolated from Yuncheng Saline Lake in China. GSS13(T) was Gram-stain-positive, strictly aerobic, rod-shaped, motile and a non-spore-former. Growth occurred at pH 5.5-8.5 (optimum pH 7.0) and at 10-45 °C (optimum 30 °C). On the basis of the results of 16S rRNA gene sequences phylogenetic analyses, GSS13(T) represents a member of the genus Salibacterium and is closely related to Salibacterium halotolerans S7(T), Salibacterium qingdaonense CM1(T) and Salibacterium halochares MSS4(T), with 16S rRNA gene sequence similarities of 98...

A non-motile, pink-coloured and rod-shaped bacterium, designated strain POA9(T), was isolated from a wastewater treatment facility, Republic of Korea. Cells were Gram-reaction-negative, aerobic, catalase-positive and oxidase-negative. The major fatty acids were C16 : 1ω5c, iso-C15 : 0, summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c) and anteiso-C15 : 0.

An unusual fluorescent pseudomonad was isolated from tomato exhibiting leaf spot symptoms similar to bacterial speck. Strains were fluorescent, oxidase- and arginine-dihydrolase-negative, elicited a hypersensitive reaction on tobacco and produced a soft rot on potato slices. However, the strains produced an unusual yellow, mucoid growth on media containing 5 % sucrose that is not typical of levan. Based on multilocus sequence analysis using 16S rRNA, gap1, gltA, gyrB and rpoD, these strains formed a distinct phylogenetic group in the genus Pseudomonas and were most closely related to Pseudomonas viridiflava within the Pseudomonassyringae complex...

A Gram-stain-negative and strictly aerobic, moderately halophilic bacterium, designated strain S1-47(T), was isolated from estuary sediment in South Korea. Cells were non-motile rods showing oxidase- and catalase-positive activities. Growth was observed at 10-30 °C (optimum, 25 °C), at pH 5.0-8.0 (optimum, pH 6.0-7.0) and in the presence of 0-6.0 % (w/v) NaCl (optimum, 2.0 %). Strain S1-47(T) contained summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c), summed feature 8 (comprising C18 : 1ω7c and/or C18 : 1ω6c) and C16 : 0 as major cellular fatty acids and ubiquinone-10 as the sole isoprenoid quinone...

Vigna unguiculata, Vigna radiata and Arachis hypogaea growing in Ethiopia are nodulated by a genetically diverse group of Bradyrhizobium strains. To determine the genetic identity and symbiotic effectiveness of these bacteria, a collection of 36 test strains originating from the root nodules of the three hosts was investigated using multilocus sequence analyses (MLSA) of core genes including 16S rRNA, recA, glnII, gyrB, atpD and dnaK. Sequence analysis of nodA and nifH genes along with tests for symbiotic effectiveness using δ(15)N analysis were also carried out...

Strain Eup a-8(T), isolated from a torch coral Euphyllia glabrescens, was characterized using a polyphasic taxonomy approach. Cells of strain Eup a-8(T) were Gram-staining-negative, aerobic, motile by means of a single polar flagellum, poly-β-hydroxybutyrate-containing, rod-shaped and formed white colonies. Optimal growth occurred at 25-30 °C, pH 7-8, and in the presence of 2 % NaCl. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain Eup a-8(T) belonged to the genus Thalassotalea and showed the highest levels of sequence similarity with respect to Thalassotalea ganghwensis JC2041(T) (97...

Two novel actinomycete isolates, designated strains NEAU-A4(T) and NEAU-A3, were isolated from rhizosphere soil of wheat (Triticumaestivum L.) and characterized using a polyphasic approach. Morphological and chemotaxonomic characteristics of the two strains coincided with those of the genus Streptomyces. The 16S rRNA gene sequence analysis showed that the two isolates exhibited 99.6 % 16S rRNA gene sequence similarity with each other and that they were most closely related to Streptomyces violaceorectus DSM 40279(T) (98...

A novel Gram-stain-negative, straight or slightly curved rod-shaped, non-spore-forming, non-flagellated, strictly aerobic strain, designated RZG4-3-1(T), was isolated from coastal seawater of Rizhao, China (119.625° E 35.517° N). The organism grew optimally at 24-28 °C, at pH 7.0 and in the presence of 2.0 % (w/v) NaCl. The strain required seawater or artificial seawater for growth, and NaCl alone did not support growth. Strain RZG4-3-1(T) contained ubiquinone 8 (Q-8) as the major respiratory quinone and contained C16 : 1ω7c and/or C16 : 1ω6c and C16 : 0 as the dominant fatty acids...

Two novel strains, J116-2(T) and J116-1, were isolated from forest soil and were taxonomically characterized by a polyphasic approach. Both strains were yellow-coloured, Gram-stain-negative, strictly aerobic, non-motile and rod-shaped bacteria. The strains were non-sporulating, catalase-positive and oxidase-negative. Strains J116-2(T) and J116-1 were able to grow at 20-32 °C, pH 6.0-8.5, and 0-0.5 % (w/v) NaCl concentration. Based on 16S rRNA gene sequence analyses, strains J116-2(T) and J116-1 formed a distinct lineage within the family Chitinophagaceae of the phylum Bacteroidetes and were closely related to genera Taibaiella (89...

Bogia coconut syndrome (BCS) is one of the lethal yellowing (LY)-type diseases associated with phytoplasma presence that are seriously threatening coconut cultivation worldwide. It has recently emerged, and is rapidly spreading in northern parts of the island of New Guinea. BCS-associated phytoplasmas collected in different regions were compared in terms of 16S rRNA gene sequences, revealing high identity among them represented by strain BCS-Bo(R). Comparative analysis of the 16S rRNA gene sequences revealed that BCS-Bo(R) shared less than a 97...
