AbstractA novel planctomycetal strain, designated ElPT, was isolated from an alga in the shallow hydrothermal vent system close to Panarea Island in the Tyrrhenian Sea. Cells of strain ElPT are spherical, form pink colonies and display typical planctomycetal characteristics including division by budding and presence of crateriform structures. Strain ElPT has a mesophilic (optimum at 30 °C) and neutrophilic (optimum at pH 7.5) growth profile, is aerobic and heterotrophic. It reaches a generation time of 29 h (µmax = 0.024 h−1). The strain has a genome size of 9.40 Mb with a G + C content of 71.1% and harbours five plasmids, the highest number observed in the phylum Planctomycetes thus far. Phylogenetically, the strain represents a novel species of the recently described genus Tautonia in the family Isosphaeraceae. A characteristic feature of the strain is its tendency to attach strongly to a range of plastic surfaces. We thus propose the name Tautonia plasticadhaerens sp. nov. for the novel species, represented by the type strain ElPT (DSM 101012T = LMG 29141T).

AbstractPan44T, a novel strain belonging to the phylum Planctomycetes, was isolated from a red biofilm in a hydrothermal area close to the island Panarea in the Tyrrhenian Sea north of Sicily, Italy. The strain forms white colonies on solid medium and displays the following characteristics: cell division by budding, formation of rosettes, presence of matrix or fimbriae and long stalks. The cell surface has an interesting and characteristic texture made up of triangles and rectangles, which leads to a pine cone-like morphology of the strain. Strain Pan44T is mesophilic (temperature optimum 26 °C), slightly alkaliphilic (pH optimum 8.0), aerobic and heterotrophic. The strain has a genome size of 6.76 Mb with a G + C content of 63.2%. Phylogenetically, the strain is a member of the family Planctomycetaceae, order Planctomycetales, class Planctomycetia. Our analysis supports delineation of strain Pan44T from all known genera in this family, hence, we propose to assign it to a novel species within a novel genus, for which we propose the name Caulifigura coniformis gen. nov., sp. nov., represented by Pan44T (DSM 29405T = LMG 29788T) as the type strain.

Two non-motile, orange- or yellow-pigmented bacteria, designated strains KYW48T and KYW147T, were isolated from seawater collected from the South Sea, Republic of Korea. Cells of both strains were Gram-reaction-negative, aerobic and catalase- and oxidase-positive. The major fatty acids of strain KYW48T were C18 : 1ω7c (35.3 %), summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1ω7c) (22.7 %), C17 : 1ω6c (19.8 %), C14 : 0 2-OH (7.4 %) and C16 : 0 (5.9 %), and those of strain KYW147T were C18 : 1ω7c (36.0 %), summed feature 3 (18.3 %), C16 : 0 (14.7 %), 11-methyl C18 : 1ω7c (10.7 %), C16 : 0 2-OH (9.1 %) and C18 : 1ω9c (8.0 %). The predominant isoprenoid quinone of both strains was ubiquinone 10 (Q-10). The DNA G+C contents of strains KYW48T and KYW147T were 63.8 and 67.2 mol%, respectively. A phylogenetic tree based on 16S rRNA gene sequences showed that strains KYW48T and KYW147T were grouped with the members of the family Erythrobacteraceae and formed a distinct clade with the members of the genus Altererythrobacter (<95.7 % sequence similarity). On the basis of the evidence presented in this study, the novel species Altererythrobacter namhicola sp. nov. (type strain KYW48T  = KCTC 22736T  = JCM 16345T) and Altererythrobacter aestuarii sp. nov. (type strain KYW147T  = KCTC 22735T  = JCM 16339T) are proposed.

An orange-pigmented bacterium, designated strain 13-9-B8T, was isolated from a seawater sample collected at Marado, Jeju Island, South Korea. The novel strain was Gram-staining-negative, non-motile, non-gliding, rod-shaped and aerobic. A phylogenetic analysis based on 16S rRNA gene sequences revealed that the strain clustered with members of the genus Lewinella of the family Saprospiraceae in the phylum Bacteroidetes and was most closely related to the species Lewinella marina (95.6 % similarity to the type strain). Strain 13-9-B8T grew optimally at 30 °C, pH 7.0 and with 2 % (w/v) NaCl. Strain 13-9-B8T contained MK-7 as the predominant menquinone and summed feature 3, iso-C15 : 0 and iso-C17 : 0 3-OH as the major fatty acids. The polar lipids detected in strain 13-9-B8T were phosphatidylethanolamine, one unidentified aminolipid, one unidentified phospholipid and eight unidentified lipids. The DNA G+C content of strain 13-9-B8T was 59.1 mol%. Based on phenotypic, chemotaxonomic and phylogenetic data presented, strain 13-9-B8T is considered to represent a novel species of the genus Lewinella, for which the name Lewinella xylanilytica sp. nov. is proposed. The type strain is 13-9-B8T ( = DSM 29526T = KCTC 32663T).

AbstractEight novel strains of the phylum Planctomycetes were isolated from different aquatic habitats. Among these habitats were the hydrothermal vent system close to Panarea Island, a public beach at Mallorca Island, the shore of Costa Brava (Spain), and three sites with brackish water in the Baltic Sea. The genome sizes of the novel strains range from 4.33 to 6.29 Mb with DNA G+C contents between 52.8 and 66.7%. All strains are mesophilic (Topt 24–30 °C) and display generation times between 17 and 94 h. All eight isolates constitute novel species of either already described or novel genera within the family Lacipirellulaceae. Two of the novel species, Posidoniimonas polymericola (type strain Pla123aT = DSM 103020T = LMG 29466T) and Bythopirellula polymerisocia (type strain Pla144T = DSM 104841T = VKM B-3442T), belong to established genera, while the other strains represent the novel genera Aeoliella gen. nov., Botrimarina gen. nov., Pirellulimonas gen. nov. and Pseudobythopirellula gen. nov. Based on our polyphasic analysis, we propose the species Aeoliella mucimassa sp. nov. (type strain Pan181T = DSM 29370T = LMG 31346T = CECT 9840T = VKM B-3426T), Botrimarina colliarenosi sp. nov.

ABSTRACTA Gram-positive and obligately anaerobic bacterium was isolated from cecal content of feral chickens in Brookings, South Dakota, USA. The microorganism grew at 37-45° C and pH 6-7.5. This strain produced acetic acid as the primary metabolic end product. Major fatty acids were C12:0, C14:0, C14:0 DMA and summed feature 1 (C13:1 at 12-13 and C14:0 aldehyde). Phylogenetic analyses based on 16S rRNA gene sequence suggested that strain SW165 belongs to the family Atopobiaceae with the closest relatives being Olsenella profusa DSM 13989T (96.33% similarity), Olsenella umbonate DSM 26220T (96.18%) and Olsenella uli DSM 7084T (96.03%). Genome sequencing revealed a genome size of 2.43 Mbp with a G+C content of 67.59 mol%, which is the highest G+C content among members of the genus Olsenella. Phylogenetic and phenotypic comparison indicated that strain SW165 represents a novel species of the genus Olsenella, for which the name Olsenella lakotia sp. nov. is proposed. The type strain is SW165 (=DSM 107283T).

Mycobacterium Simiae

Four strains isolated in the last 15 years were revealed to be identical in their 16S rRNA gene sequences to MCRO19, the sequence of which was deposited in GenBank in 1995. In a polyphasic analysis including phenotypic and genotypic features, the five strains (including MCRO19), which had been isolated in four European countries, turned out to represent a unique taxonomic entity. They are scotochromogenic slow growers and are genetically related to the group that included Mycobacterium simiae and 15 other species. The novel species Mycobacterium europaeum sp. nov. is proposed to accommodate these five strains. Strain FI-95228T ( = DSM 45397T  = CCUG 58464T) was chosen as the type strain. In addition, a thorough revision of the phenotypic and genotypic characters of the species related to M. simiae was conducted which leads us to suggest the denomination of the ‘Mycobacterium simiae complex’ for this group.

Species Analysis

A polyphasic taxonomic evaluation of presumptive strains representative of the genus Glycomyces held within the Agricultural Research Service Culture Collection resulted in the discovery of three novel species. Analysis of the whole cell sugar content of these novel species, as well as of two species presently assigned to the genus, revealed that the whole cell sugar pattern was different from that reported in the formal description of the genus Glycomyces. The sugars present in all strains studied included ribose, xylose, mannose and galactose rather than xylose and arabinose as reported in the original description of the genus. Moreover, the menaquinone patterns observed for the novel species also deviated from the original genus description. The formal description of the genus Glycomyces is emended to reflect these new data. The novel species proposed and described are Glycomyces algeriensis sp. nov. (type strain NRRL B-16327T=DSM 44727T), Glycomyces arizonensis sp. nov. (type strain NRRL B-16153T=DSM 44726T) and Glycomyces lechevalierae sp. nov. (type strain NRRL B-16149T=DSM 44724T).

Thirty-three suspected strains of the family Pasteurellaceae isolated from the oral cavity of polar and brown bears were characterized by genotypic and phenotypic tests. Phylogenetic analysis of partial 16S rRNA gene and rpoB sequences showed that the investigated isolates formed two closely related monophyletic groups, representing two novel species of a new genus. Based on 16S rRNA gene sequence comparison Bibersteinia trehalosi was the closest related species with a validly published name, with 95.4 % similarity to the polar bear group and 94.4 % similarity to the brown bear group. Otariodibacter oris was the closest related species based on rpoB sequence comparison with a similarity of 89.8 % with the polar bear group and 90 % with the brown bear group. The new genus could be separated from existing genera of the family Pasteurellaceae by three to ten phenotypic characters, and the two novel species could be separated from each other by two phenotypic characters. It is proposed that the strains should be classified as representatives of a new genus, Ursidibacter gen. nov., with two novel species: the type species Ursidibacter maritimus sp. nov., isolated from polar bears (type strain Pb43106T = CCUG 65144T = DSM 28137T, DNA G+C content 39.3 mol%), and Ursidibacter arcticus sp. nov., isolated from brown bears (type strain Bamse61T = CCUG 65145T = DSM 28138T).

A haloalkaliphilic strain XQ-INN 246T was isolated from the sediment of a salt pond in Inner Mongolia Autonomous Region, China. Cells of the strain were rods, motile and strictly aerobic. The strain was able to grow in the presence of 2.6–5.3 M NaCl (optimum concentration is 4.4 M) at 30–50 °C (optimum temperature is 42 °C) and pH 7.0–10.0 (optimum pH is 8.0–8.5). The whole genome sequencing of strain XQ-INN 246T revealed a genome size of 4.52 Mbp and a DNA G+C content of 62.06 mol%. Phylogenetic tree based on 16S rRNA gene sequences and concatenated amino acid sequences of 122 single-copy conserved proteins revealed a robust lineage of the strain XQ-INN 246T with members of related genera of the family Natrialbaceae . The strain possessed the polar lipids of phosphatidylglycerol and phosphatidylglycerol phosphate methyl ester. No glycolipids were detected. Based on phylogenetic analysis, phenotypic characteristics, chemotaxonomic properties and genome relatedness, the isolate was proposed as the type strain of a novel species of a new genus within the family Natrialbaceae, for which the name Salinadaptatus halalkaliphilus gen. nov., sp. nov. is proposed. The type strain is XQ-INN 246T (=CGMCC 1.16692T=JCM 33751T).

A Gram-staining-negative, non-gliding, orange-pigmented bacterial strain, designated HMF2925T, was isolated from fresh water in Korea. The phylogenetic tree based on 16S rRNA gene sequences showed that strain HMF2925T formed a distinct lineage within the genus Emticicia. Strain HMF2925T was closely related to Emticicia oligotrophica DSM 17448T (95.5 %) and Emticicia ginsengisoli Gsoil 085T (94.1 %). The major fatty acids of strain HMF2925T were summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c), iso-C15 : 0, C16 : 1ω5c and C16 : 0.The major polar lipids of strain HMF2925T were phosphatidylethanolamine, phosphatidylinositol, diphosphatidylglycerol, phosphatidylglycerol, an unidentified glycolipid, two unidentified amino lipids and three unidentified polar lipids. The DNA G+C content of strain HMF2925T was 36.5 mol%. On the basis of the evidence presented in this study, strain HMF2925T represents a novel species of the genus Emticicia, for which the name Emticicia aquatica sp. nov. is proposed. The type strain is HMF2925T ( = KCTC 42574T = CECT 8858T).
