Most picornaviruses of the family Picornaviridae are relatively well known, but there are certain “neglected” genera like Bopivirus, containing a single uncharacterised sequence (bopivirus A1, KM589358) with very limited background information. In this study, three novel picornaviruses provisionally called ovipi-, gopi- and bopivirus/Hun (MW298057-MW298059) from enteric samples of asymptomatic ovine, caprine and bovine respectively, were determined using RT-PCR and dye-terminator sequencing techniques. These monophyletic viruses share the same type II-like IRES, NPGP-type 2A, similar genome layout (4-3-4) and cre-localisations. Culture attempts of the study viruses, using six different cell lines, yielded no evidence of viral growth in vitro. Genomic and phylogenetic analyses show that bopivirus/Hun of bovine belongs to the species Bopivirus A, while the closely related ovine-origin ovipi- and caprine-origin gopivirus could belong to a novel species “Bopivirus B” in the genus Bopivirus. Epidemiological investigation of N = 269 faecal samples of livestock (ovine, caprine, bovine, swine and rabbit) from different farms in Hungary showed that bopiviruses were most prevalent among <12-month-old ovine, caprine and bovine, but undetectable in swine and rabbit. VP1 capsid-based phylogenetic analyses revealed the presence of multiple lineages/genotypes, including closely related ovine/caprine strains, suggesting the possibility of ovine–caprine interspecies transmission of certain bopiviruses.

A New Species

In this paper, we report a new asexual-morph taxon belonging to the family Cordycipitaceae (Hypocreales), which is associated with a sexual morph of an ophioceras-like taxon on submerged wood collected from Baoshan, Yunnan, China. Morphologically, this new taxon is similar to known asexual morphs of Lecanicillium and characterized by conidiophores arising from hyaline hyphae, with gregarious, ellipsoid to ovoid, aseptate conidia. Phylogenetic analyses of a combined LSU, SSU, tef1-α and ITS sequence dataset positions our taxon in Cordycipitaceae and close to Lecanicillium sp. (CBS 639.85) and L. primulinum. Lecanicillium subprimulinum is introduced as a new species with support from molecular data.

Bacterium Strain

A Gram-negative, non-spore-forming, yellow-pigmented bacterium, strain N4T, was isolated from a nickel-complexed cyanide-degrading bioreactor and subjected to a polyphasic taxonomic study. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain N4T is affiliated to the genus Chryseobacterium of the family Flavobacteriaceae. The levels of 16S rRNA gene sequence similarity between strain N4T and the type strains of all known Chryseobacterium species were 93.2–95.8 %, suggesting that strain N4T represents a novel species within the genus Chryseobacterium. The strain contained iso-C15 : 0 and summed feature 4 as the major fatty acids and menaquinone MK-6 as the predominant respiratory quinone. The G+C content of the genomic DNA was 38.2 mol%. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain N4T represents a novel species of the genus Chryseobacterium, for which the name Chryseobacterium caeni sp. nov. is proposed. The type strain is N4T (=KCTC 12506T=CCBAU 10201T=DSM 17710T).

ABSTRACTThe OM43 clade within the familyMethylophilaceaeofBetaproteobacteriarepresents a group of methylotrophs that play important roles in the metabolism of C1compounds in marine environments and other aquatic environments around the globe. Using dilution-to-extinction cultivation techniques, we successfully isolated a novel species of this clade (here designated MBRS-H7) from the ultraoligotrophic open ocean waters of the central Red Sea. Phylogenomic analyses indicate that MBRS-H7 is a novel species that forms a distinct cluster together with isolate KB13 from Hawaii (Hawaii-Red Sea [H-RS] cluster) that is separate from the cluster represented by strain HTCC2181 (from the Oregon coast). Phylogenetic analyses using the robust 16S-23S internal transcribed spacer revealed a potential ecotype separation of the marine OM43 clade members, which was further confirmed by metagenomic fragment recruitment analyses that showed trends of higher abundance in low-chlorophyll and/or high-temperature provinces for the H-RS cluster but a preference for colder, highly productive waters for the HTCC2181 cluster. This potential environmentally driven niche differentiation is also reflected in the metabolic gene inventories, which in the case of the H-RS cluster include those conferring resistance to high levels of UV irradiation, temperature, and salinity. Interestingly, we also found different energy conservation modules between these OM43 subclades, namely, the existence of the NADH:quinone oxidoreductase complex I (NUO) system in the H-RS cluster and the nonhomologous NADH:quinone oxidoreductase (NQR) system in the HTCC2181 cluster, which might have implications for their overall energetic yields.

During a survey of saprobic microfungi in Thailand, a dothideomycetous fungus was found on a dead twig of Delonix regia, on the Chiang Mai University campus. This fungus is characterized by fully immersed ascomata under a small blackened pseudoclypeus, pseudoparenchymatous peridium, cellular pseudoparaphyses, cylindrical-clavate asci with a distinct pedicel, overlapping 3–4-seriate, pale to dark brown, broadly fusoid, 7–9-transversally septate ascospores with a vertical septum in nearly all median cells. Multigene phylogenetic analyses, using partial sequences from the 28S nrRNA gene (LSU), 18S nrRNA gene (SSU), internal transcribed spacer regions and intervening 5.8S nrRNA gene (ITS) of the nrDNA operon and the translation elongation factor 1-alpha region (TEF) demonstrated a monophyletic affiliation of the new strain, accommodating the species of Phaeoseptum in the family Phaeoseptaceae. With further morphological and phylogenetic investigations, we justify the new fungus as a novel species, Phaeoseptum hydei in Phaeoseptaceae. Detailed descriptions and illustrations are provided for Phaeoseptum hydei and this novel species compared with the remaining species found in the genus. An updated checklist of microfungi recorded on Delonix regia from around the world is also provided.

An obligately aerobic, spherical, non-motile, pale-yellow pigmented bacterium was isolated from a piece of leaf of seagrass, Enhalus acoroides (L.f.) Royle, grown in Okinawa, Japan and was subjected to a polyphasic taxonomic study. Phylogenetic analyses based on 16S rRNA gene sequences revealed that the novel isolate N5FB36-5T shared approximately 96–98 % sequence similarity with the species of the genus Pelagicoccus of the family Puniceicoccaceae within the phylum ‘Verrucomicrobia’. The DNA–DNA relatedness values of strain N5FB36-5T with Pelagicoccus mobilis 02PA-Ca-133T and Pelagicoccus albus YM14-201T were below 70 %, which is accepted as the phylogenetic definition of a novel species. β-Lactam antibiotic susceptibility test and amino acid analysis of the cell wall hydrolysates indicated the absence of muramic acid and diaminopimelic acid in the cell walls, which suggested that this strain lacks an ordinary Gram-negative type of peptidoglycan in the cell wall. The DNA G+C content of strain N5FB36-5T was 51.6 mol%; MK-7 was the major menaquinone; and the presence of C16 : 0, C16 : 1 ω7c and anteiso-C15 : 0 as the major cellular fatty acids supported the identification of the novel isolate as a member of the genus Pelagicoccus. On the basis of polyphasic taxonomic data, it was concluded that this strain should be classified as a novel species of the genus Pelagicoccus, for which the name Pelagicoccus croceus sp. nov. is proposed. The type strain is N5FB36-5T (=MBIC08282T=KCTC 12903T).

AbstractPlanctomycetes are ubiquitous bacteria with fascinating cell biological features. Strains available as axenic cultures in most cases have been isolated from aquatic environments and serve as a basis to study planctomycetal cell biology and interactions in further detail. As a contribution to the current collection of axenic cultures, here we characterise three closely related strains, Poly24T, CA51T and Mal33, which were isolated from the Baltic Sea, the Pacific Ocean and the Mediterranean Sea, respectively. The strains display cell biological features typical for related Planctomycetes, such as division by polar budding, presence of crateriform structures and formation of rosettes. Optimal growth was observed at temperatures of 30–33 °C and at pH 7.5, which led to maximal growth rates of 0.065–0.079 h−1, corresponding to generation times of 9–11 h. The genomes of the novel isolates have a size of 7.3–7.5 Mb and a G + C content of 57.7–58.2%. Phylogenetic analyses place the strains in the family Pirellulaceae and suggest that Roseimaritima ulvae and Roseimaritima sediminicola are the current closest relatives. Analysis of five different phylogenetic markers, however, supports the delineation of the strains from members of the genus Roseimaritima and other characterised genera in the family. Supported by morphological and physiological differences, we conclude that the strains belong to the novel genus Rosistilla gen. nov. and constitute two novel species, for which we propose the names Rosistilla carotiformis sp. nov. and Rosistilla oblonga sp. nov. (the type species). The two novel species are represented by the type strains Poly24T (= DSM 102938T = VKM B-3434T = LMG 31347T = CECT 9848T) and CA51T (= DSM 104080T = LMG 29702T), respectively.

Two Bifidobacterium strains, TMW 2.2057T and TMW 2.1764 were isolated from two different homemade water kefirs from Germany. Both strains were oxidase- and catalase-negative and Gram-staining-positive. Cells were non-motile, irregular rods that were aerotolerant anaerobes. On basis of fructose 6-phosphate phosphoketolase activity, they were assigned to the family Bifidobacteriaceae. Comparative analysis of 16S rRNA and concatenated housekeeping genes (clpC, dnaB, dnaG, dnaJ, hsp60 and rpoB) demonstrated that both strains represented a member of the genus Bifidobacterium , with Bifidobacterium subtile DSM 20096T as the closest phylogenetic relative (98.35 % identity). Both strains can be distinguished using randomly amplified polymorphic DNA fingerprinting. Analysis of concatenated marker gene sequences as well as average nucleotide identity by blast (ANIb) and in silico DNA–DNA hybridization (isDDH) calculations of their genome sequences confirmed Bifidobacterium subtile DSM 20096T as the closest relative (87.91 and 35.80 % respectively). All phylogenetic analyses allow differentiation of strains TMW 2.2057T and TMW 2.1764 from all hitherto described species of the genus Bifidobacterium with validly published names. We therefore propose a novel species with the name Bifidobacterium tibiigranuli, for which TMW 2.2057T (=DSM 108414T=LMG 31086T) is the type strain.

Strain CBA3205T is a Gram-stain-negative, non-motile and rod-shaped bacterium that was isolated from the seashore sand of Jeju Island in South Korea. Based on the phylogenetic analysis, the most closed related species was Croceitalea eckloniae DOKDO 025T, with 94.8 % sequence similarity for the 16S rRNA gene. Strain CBA3205T was observed to grow optimally at 25–30 °C and at pH 8.5 in the presence of 2–3 % (w/v) NaCl. The major fatty acids of strain CBA3205T were iso-C15 : 0, iso-C15 : 1 G, and iso-C17 : 0 3-OH. The major respiratory quinone was MK-6 and the major polar lipids were two unidentified amino-group-containing phospholipids and an unidentified polar lipid. The G+C content of the genomic DNA of strain CBA3205T was 62.5 mol%. Based on the phenotypic, genotypic and phylogenetic analyses, strain CBA3205T was considered to be a novel species belonging to the genus Croceitalea within the family Flavobacteriaceae, for which the name Croceitalea litorea sp. nov. is proposed. The type strain is CBA3205T ( = KACC 17669T = JCM 19531T).

AbstractA novel bacterial strain designated ADMK78T was isolated from the saline desert soil. The cells were rod-shaped, Gram-negative, and non-motile. The strain ADMK78T grows best at 28°C and pH 7.0 and can tolerate up to 2% (w/v) NaCl. Based on 16S rRNA gene phylogeny, the strain ADMK78T belongs to the genus Rhizobium, with the highest similarity to Rhizobium wuzhouense W44T (98.7%) and Rhizobium ipomoeae shin9-1T (97.9%). Core-genes based phylogenetic analysis revealed that the strain ADMK78T forms a distinct branch in between Rhizobium ipomoeae shin9-1T and Rhizobium selenitireducens BAA-1503T. The average nucleotide identity of ADMK78T was less than 82%, to members of the family Rhizobiaceae. The genomic DNA G+C content of strain ADMK78T is 58.6 mol%. The major fatty acids of strain ADMK78T were C18:0 and C18:1 ω7c. The strain ADMK78T showed differences in physiological, phenotypic, and protein profiles estimated by MALDI-TOF MS to its closest relatives. Based on the phenotypic, chemotaxonomic properties, and phylogenetic analyses, the strain ADMK78T could be distinguished from the recognized species of the genus Rhizobium. It is suggested to represent a novel species of this genus, for which the name Rhizobium desertarenae sp. nov. is proposed. The type strain is ADMK78T (=MCC 3400T; KACC 21383T; JCM 33657T).

A fungal strain designated KNU16-007, belonging to the family Botryosphaeriaceae, was isolated from soil in Daegu, Korea. Phylogenetic analyses based on the concatenated nucleotide sequences of the ITS and TEF-1α regions, showed that the isolate resides in a clade together with Diplodia species but occupies a distinct phylogenetic position. Conidial dimensions of strain KNU16-007 (22.7–29.3 μm × 8.9–10.9 μm) or its conidial length:width ratio were significantly differed from those of the closely related D. sapinea, D. intermedia, D. scrobiculata, D. seriata, D. crataegicola, D. rosacearum, and D. citricarpa clearly indicating morphological differences from these species. Detailed descriptions, illustrations, and discussions regarding the morphological and phylogenetic analyses of the closely related species are provided to support the novelty of the isolated species. The results of phylogenetic analysis and morphological observations indicate that strain KNU16-007 represents a novel species in the genus Diplodia, for which the name Diplodia parva sp. nov. is proposed.
