A Gram-stain-negative bacterial strain, designated CA10T, was isolated from bovine raw milk sampled in Anseong, Republic of Korea. Cells were yellow-pigmented, aerobic, non-motile bacilli and grew optimally at 30?°C and pH 7.0 on tryptic soy agar without supplementation of NaCl. Phylogenetic analysis based on the 16S rRNA gene sequences revealed that strain CA10T belonged to the genus Chryseobacterium, family Flavobacteriaceae, and was most closely related to Chryseobacterium indoltheticum ATCC 27950T (98.75?% similarity). The average nucleotide identity and digital DNA-DNA hybridization values of strain CA10T were 94.4 and 56.9?%, respectively, relative to Chryseobacterium scophthalmum DSM 16779T, being lower than the cut-off…
A Gram-stain-negative, rod-shaped and red-pigmented strain, HME7025T, was isolated from freshwater sampled in the Republic of Korea. Phylogenetic analysis based on its 16S rRNA gene sequence revealed that strain HME7025T formed a lineage within the family Cytophagaceae of the phylum Bacteroidetes. Strain HME7025T was closely related to the genera Pseudarcicella, Arcicella and Flectobacillus. The 16S rRNA gene sequence similarity values of strain HME7025T were under 94.5?% to its closest phylogenetic neighbours. The major fatty acids of strain HME7025T were iso-C15?:?0 (41.9?%), summed feature 3 (comprising C16?:?1?7c and/or C16?:?1?6c; 12.2?%) and anteiso-C15?:?0 (10.8?%). The major respiratory quinone was menaquinone-7. The major…
A bacterial strain designated as P08T was isolated from laboratory tap water during a water quality assessment in University of Malaya, Malaysia. The strain was a Gram-negative, rod-shaped, nonmotile, and aerobic bacterium. Complete genome of P08T comprised of a 2,820,660 bp chromosome with a G + C content of 36.43%. Both 16S rRNA phylogeny and phylogenetic tree inferred from the core gene matrix demonstrated that P08T formed a hitherto unknown subline within the family Neisseriaceae. Ortho average nucleotide identity (OrthoANI) values and the percentage of conserved proteins (POCP) calculated from complete genome sequence indicated low relatedness between P08T and its phylogenetic neighbors. Respiratory…
Members of the major candidate phylum Dependentiae (a.k.a. TM6) are widespread across diverse environments from showerheads to peat bogs; yet, with the exception of two isolates infecting amoebae, they are only known from metagenomic data. The limited knowledge of their biology indicates that they have a long evolutionary history of parasitism. Here, we present Chromulinavorax destructans (Strain SeV1) the first isolate of this phylum to infect a representative from a widespread and ecologically significant group of heterotrophic flagellates, the microzooplankter Spumella elongata (Strain CCAP 955/1). Chromulinavorax destructans has a reduced 1.2 Mb genome that is so specialized for infection that…
Members of the genus Nocardia are widespread in diverse environments; a wide range of Nocardia species are known to cause nocardiosis in several animals, including cat, dog, fish, and humans. Of the pathogenic Nocardia species, N. seriolae is known to cause disease in cultured fish, resulting in major economic loss. We isolated two N. seriolae strains, CK-14008 and EM15050, from diseased fish and sequenced their genomes using the PacBio sequencing platform. To identify their genomic features, we compared their genomes with those of other Nocardia species. Phylogenetic analysis showed that N. seriolae shares a common ancestor with a putative human…
Two hitherto unknown bacteria (strains 313T and 352) were recovered from the faeces of Tibetan antelopes on the Tibet-Qinghai Plateau, PR China. Cells were rod-shaped and Gram-stain-positive. The optimal growth conditions were at 37?°C and pH 7. The isolates were closely related to Actinotignum sanguinis (92.6?% 16S rRNA gene sequence similarity), Arcanobacterium haemolyticum (92.5?%), Actinotignum schaalii (92.4?%), Actinobaculum massiliense (92.2?%) and Flaviflexus huanghaiensis (91.6?%). Phylogenetic analyses showed that strains 313T and 352 clustered independently in the vicinity of the genera Actinotignum, Actinobaculum and Flaviflexus, but could not be classified clearly as a member of any of these genera. Phylogenomic analysis…
Three mesophilic, Gram-stain-positive, aerobic bacterial strains, designated Uno3T, Uno11T and Uno16T, were isolated from a soil-like granular micro-organism mass (termed Tengu-no-mugimeshi) collected from Tsumagoi, Gunma, Japan. They grow at 11-37?°C?and pH 4.0-8.0, form branched mycelia, and have a G+C?content between 49.4-50.3?mol%. The major menaquinone and fatty acid of Uno3T are MK-9 and iso-C16?:?0, respectively, whereas Uno11T and Uno16T share MK-9 (H2) and C16?:?1-2OH. The major cell-wall sugars are mannose (Uno3T and Uno11T) and glucose (Uno16T). Phylogenetic analysis based on 16S rRNA gene sequences indicated that these three strains belong to the order Ktedonobacterales and are most closely related to Dictyobacter…
This article reports the full genome sequence of Sphingomonas panacis DCY99T (=KCTC 42347T =JCM30806T), which is a Gram-negative rod-shaped, non-spore forming, motile bacterium isolated from rusty ginseng root in South Korea. A draft genome of S. panacis DCY99T and a single circular plasmid were generated using the PacBio platform. Antagonistic activity experiment showed S. panacis DCY99T has the plant growth promoting effect. Thus, the genome sequence of S. panacis DCY99T may contribute to biotechnological application of the genus Sphingomonas in agriculture.
