Korean Ginseng

A Gram-negative, aerobic bacterium, designated CG20106T, was isolated from the surface tissues of rusty root lesions of Korean ginseng. Phylogenetic analysis of the 16S rRNA gene sequence revealed that this isolate represents a hitherto unknown subline within the genus Pseudomonas. Strain CG20106T was catalase- and oxidase-positive, motile and rod-shaped. The overall phenotypic features of the ginseng isolate were similar to those of Pseudomonas cedrina, Pseudomonas migulae and Pseudomonas azotoformans. However, several physiological and chemotaxonomic properties can be weighted to distinguish the isolate from these organisms. The major fatty acids were C16 : 1 ω7c and/or iso-C15 : 0 2-OH (summed feature 3, 36·4±0·4 %), C16 : 0 (27·5±0·7 %) and C18 : 1 ω7c (19·4±0·2 %). The DNA G+C content was 61·4 mol%. On the basis of the polyphasic results revealed in this study, the name Pseudomonas panacis sp. nov. is proposed for strain CG20106T. The type strain is CG20106T (=IMSNU 14100T=CIP 108524T=KCTC 12330T).

A micro-organism, DCY12T, comprising Gram-negative, non-motile, pale-yellow rods was isolated from soil from a ginseng field in South Korea and was investigated to determine its taxonomic status. It grew optimally at 30 °C and at pH 7.0, the G+C content of its DNA was 40.5 mol%, the major components of the fatty acid profile were C16 : 0 and C18 : 1 and the major ubiquinone was Q-8. A phylogenetic analysis based on the 16S rRNA gene sequence revealed that the novel isolate was most closely related to Hydrocarboniphaga effusa AP103T (89.2 %), Nevskia ramosa Soe1 (88.8 %) and Pseudomonas aeruginosa ATCC 10145T (83.2 %). The phenotypic, physiological, metabolic and phylogenetic properties of DCY12T suggest that it represents a novel genus (class Gammaproteobacteria) and species, for which the name Solimonas soli gen. nov., sp. nov. is proposed. The type strain of Solimonas soli is DCY12T (=KCTC 12834T =LMG 24014T).

A novel, non-pigmented, rod-shaped, Gram-negative strain was isolated from mesotrophic lake water in Zealand, Denmark. Phylogenetic analysis of the 16S rRNA gene sequence of the bacterium, designated strain 389T, indicated that the strain belonged to the genus Vogesella and formed a monophyletic group with Vogesella perlucida DS-28T (99.1 % nucleotide similarity); it was less related to Vogesella indigofera ATCC 19706T (96.9 % similarity) and Vogesella lacus LMG 24504T (96.8 % similarity). Hybridization of DNA from strain 389T and V. perlucida demonstrated a reassociation of 50.6±9.6 %. The DNA G+C content of strain 389T was 61.2 mol%. The fatty acid profile of the strain differed from those of the other strains representing the genus Vogesella by a high content of C16 : 1 ω7c and/or iso-C15 : 0 2-OH (71.6 %) and a lower content of C16 : 0. Strain 389T was capable of degrading peptidoglycan and had chitinase and lysozyme activities, possibly associated with the degradation of peptidoglycan, and had capacity for degradation of several other polymer compounds. Based on phenotypic and genotypic characteristics, strain 389T represents a novel species, for which we propose the name Vogesella mureinivorans sp. nov. The type strain is 389T (=DSM 21247T =LMG 25302T).

A Gram-negative, rod-shaped, motile, non-spore-forming bacterium, designated strain A62-14BT, was isolated from a constant-temperature, spring-fed, freshwater lake. On the basis of the complete 16S rRNA gene sequence, strain A62-14BT was shown to belong to the class Gammaproteobacteria, being most closely related to Rheinheimera sp. HTB082 (96.2 % sequence similarity), Rheinheimera baltica (95.01 %), Rheinheimera pacifica (96.35 %), Rheinheimera perlucida and Alishewanella fetalis (95.9 %). The major fatty acids (C16 : 1 ω7c, 38.56 %; C16 : 0, 19.04 %; C12 : 0 3-OH, 12.83 %; C18 : 1 ω7c, 7.70 %) and the motility of strain A62-14BT support its affiliation to the genus Rheinheimera. The salt intolerance of strain A62-14BT, together with the results of other physiological and biochemical tests, allowed the differentiation of this strain from the three species of the genus Rheinheimera with validly published names. Therefore strain A62-14BT represents a novel species of the genus Rheinheimera, for which the name Rheinheimera texasensis sp. nov. is proposed. The type strain is A62-14BT (=ATCC BAA-1235T=DSM 17496T). The description of the genus Rheinheimera is emended to reflect the halointolerance and freshwater origin of strain A62-14BT.

A novel strain, R2A16-10T, was isolated from greenhouse soil in Yeoju, Korea. The taxonomy of strain R2A16-10T was studied by using polyphasic methods. On the basis of 16S rRNA gene sequence analyses, strain R2A16-10T was found to be phylogenetically related to type strains of Dyella species (96.7–96.9 %), Frateuria aurantia DSM 6220T (96.5 %), Fulvimonas soli LMG 19981T (96.3 %) and Rhodanobacter species (94.9–95.7 %). Strain R2A16-10T, which produced yellow-coloured colonies, was Gram-negative, rod-shaped (0.3–0.4×1.5–3.5 μm) and motile. The predominant fatty acids were 17 : 1 iso ω9c (25.5 %), 15 : 0 iso (18.7 %) and 17 : 0 iso (14.6 %), and the major hydroxy fatty acids were 11 : 0 iso 3-OH (5.0 %), 13 : 0 iso 3-OH (3.4 %) and 17 : 0 iso 3-OH (1.0 %). The major isoprenoid quinone was Q-8. The G+C content of the DNA of the type strain was 63.0 mol%. On the basis of the data from this study, strain R2A16-10T represents a novel species of the genus Dyella, for which the name Dyella yeojuensis sp. nov. is proposed. The type strain is R2A16-10T (=KACC 11405T=DSM 17673T).

Novel Genus And Species

The taxonomic position of a marine, gliding, pink-pigmented, aerobic, heterotrophic and Gram-negative bacterium was established using a polyphasic approach. 16S rRNA gene sequence analysis indicated that the strain was a member of the phylum ‘Bacteroidetes’ in which it occupied a separate lineage. The predominant cellular fatty acids were C15 : 0 iso, C17 : 0 iso 3-OH, summed feature 3 and summed feature 4. The DNA G+C content was 48·7 mol%. Phylogenetic evidence and the results of phenotypic, genotypic and chemotaxonomic analyses strongly support the assignment of the newly isolated bacterium as a member of a novel genus and species, for which the name Pontibacter actiniarum gen. nov., sp. nov. is proposed. The type strain is KMM 6156T (=KCTC 12367T=LMG 23027T). It is also proposed that the illegitimate names Reichenbachia and Reichenbachia agariperforans are replaced with Reichenbachiella and Reichenbachiella agariperforans, respectively.

AbstractStrain CECT 9734 T, a Gram-negative, aerobic, chemoorganotrophic bacterium, motile by polar flagella, was isolated from cultured European seabass, Dicenthrarchus labrax, in Spain. It grows from 5 to 42 ºC, 6–9 pH and 1–12% total salinity. Major cellular fatty acids are C15:0 iso, summed feature 9 (C17:1 iso w9c/C16:0 10-methyl) and C17:0 iso. The genome size is 2.5 Mbp and G + C content is 49.5 mol%. Comparative analysis of the 16S rRNA gene sequence shows that the strain is a member of Pseudidiomarina, with highest similarities with Pseudidiomarina halophila (97.0%) and Pseudidiomarina salinarum (96.9%). Phylogenomic tree based on UBCG program shows P. halophila as its closest relative. ANI and in-silico DDH with other Pseudidiomarina spp. are lower than 87 and 20%, respectively, suggesting that strain CECT 9734 T represents a new species, for which we propose the name Pseudidiomarina piscicola sp. nov. and CECT 9734 T (= LUBLD50 7aT = LMG 31044 T) as type strain.

A Gram-stain-positive, endospore-forming, rod-shaped bacterium, designated XJ259T, was isolated from a cold spring sample from Xinjiang Uyghur Autonomous Region, China. The isolate grew optimally at 20–30 °C and pH 7.3–7.8. Comparative analysis of the 16S rRNA gene sequence showed that isolate XJ259T belonged phylogenetically to the genus Paenibacillus, and was most closely related to Paenibacillus xinjiangensis B538T (with 96.6 % sequence similarity), Paenibacillus glycanilyticus DS-1T (96.3 %) and Paenibacillus castaneae Ch-32T (96.1 %), sharing less than 96.0 % sequence similarity with all other members of the genus Paenibacillus. Chemotaxonomic analysis revealing menaquinone-7 (MK-7) as the major isoprenoid quinone, diphosphatidylglycerol, phosphatidylethanolamine and two unknown phosphoglycolipids as the major cellular polar lipids, a DNA G+C content of 47.0 mol%, and anteiso-C15 : 0 and C16 : 0 as the major fatty acids supported affiliation of the new isolate to the genus Paenibacillus. Based on these data, isolate XJ259T is considered to represent a novel species of the genus Paenibacillus, for which the name Paenibacillus algorifonticola sp. nov. is proposed. The type strain is XJ259T ( = CGMCC 1.10223T  = JCM 16598T).

The 16S Rrna Gene

A novel nitrogen-fixing fermentative bacterium, designated as YA01T, was isolated from Nakabusa hot springs in Japan. The short-rod cells of strain YA01T were Gram-positive and non-sporulating. Phylogenetic trees of the 16S rRNA gene sequence and concatenated sequences of 40 single-copy ribosomal genes revealed that strain YA01T belonged to the genus Caldicellulosiruptor and was closely related to Caldicellulosiruptor hydrothermalis 108T, Caldicellulosiruptor bescii DSM 6725T and Caldicellulosiruptor kronotskyensis 2002T. The 16S rRNA gene sequence of strain YA01T shares less than 98.1 % identity to the known Caldicellulosiruptor species. The G+C content of the genomic DNA was 34.8 mol%. Strain YA01T shares low genome-wide average nucleotide identity (90.31–91.10 %), average amino acid identity (91.45–92.10 %) and <70 % digital DNA–DNA hybridization value (41.8–44.2 %) with the three related species of the genus Caldicellulosiruptor . Strain YA01T grew at 50–78 °C (optimum, 70 °C) and at pH 5.0–9.5 (optimum, pH 6.5). Strain YA01T mainly produced acetate by consuming d(+)-glucose as a carbon source. The main cellular fatty acids were iso-C17 : 0 (35.7 %), C16 : 0 (33.3 %), DMA16 : 0 (6.6 %) and iso-C15 : 0 (5.9 %). Based on its distinct phylogenetic position, biochemical and physiological characteristics, and the major cellular fatty acids, strain YA01T is considered to represent a novel species of the genus Caldicellulosiruptor for which the name Caldicellulosiruptor diazotrophicus sp. nov. is proposed (type strain YA01T=DSM 112098T=JCM 34253T).

Gene Sequence Analysis

Two Gram-negative, vibrioid, phototrophic, purple non-sulfur strains, JA131T and JA135T, were isolated from marine habitats. Strain JA131T is non-motile but strain JA135T is motile by means of a pair of monopolar flagella. Both strains have an obligate requirement for NaCl for growth. The intracellular photosynthetic membranes of the two novel strains are of the vesicular type. Bacteriochlorophyll a and probably rhodovibrine are present as photosynthetic pigments. Niacin, thiamine and p-aminobenzoic acid are required as growth factors for both novel strains. Based on 16S rRNA gene sequence analysis, morphological and physiological characteristics, strains JA131T and JA135T are significantly different from each other and from other species of the genus Roseospira and thus represent two novel species for which the names Roseospira visakhapatnamensis sp. nov. and Roseospira goensis sp. nov. are proposed, respectively. The type strain of Roseospira visakhapatnamensis sp. nov. is JA131T (=ATCC BAA-1365T=JCM 14190T) and the type strain of Roseospira goensis sp. nov. is JA135T (=ATCC BAA-1364T=JCM 14191T).
