Therefore, we propose that strain 501str8T represents a novel species of the genus Muricauda, for which the name Muricauda oceani sp. nov. is suggested. The type strain is 501str8T (=JCM 33902T=MCCC 1K04567T).A Gram-reaction-positive, endospore-forming bacterium, designated strain P1T, was isolated from water samples collected from Pasinler Hot Spring and characterized using a polyphasic approach to clarify its taxonomic position. Strain P1T was found to have chemotaxonomic and morphological characteristics consistent with its classification in the genus Bacillus. The strain shared the highest 16S rRNA gene sequence identity values with Bacillus thermolactis R-6488T (97.6 %) and Bacillus kokeshiiformis MO-04T (97.2 %) and formed a distinct clade with both type strains in the phylogenetic trees based on 16S rRNA gene sequences. Strain P1T could grow optimally at 55 °C and in the presence of 2 % NaCl. The organism was found to contain meso-diaminopimelic acid as the diagnostic diamino acid in the cell-wall peptidoglycan. The major polar lipids were diphosphatidylglycerol and phosphatidylglycerol. The predominant menaquinone was determined to be MK-7. The major cellular fatty acids were identified as iso-C15 0, iso-C17 0 and anteiso-C17 0. Based upon the consensus of phenotypic and phylogenetic analyses, strain P1T represents a novel species of the genus Bacillus, for which the name Bacillus pasinlerensis sp. Corticosterone in vitro nov. is proposed. The type strain is P1T (=DSM 107529T=CECT 9885T=NCCB 100674T).According to Rule 37a of the International Code of Nomenclature of Prokaryotes, the name of a taxon must be changed if the nomenclatural type of the taxon is excluded. Recently, in a transfer of actinobacterial species, three species - Friedmanniella endophytica Tuo et al. 2016, Lysinimicrobium sediminis Hamada et al. 2017 and Lechevalieria rhizosphaerae Zhao et al. 2017 - were not transferred with their type species. Therefore, to resolve these nomenclatural issues, Microlunatus kandeliicorticis nom. nov., Demequina sediminis comb. nov. and Lentzea rhizosphaerae comb. nov. are proposed, respectively.Verotoxigenic Escherichia coli (VTEC) are food- and water-borne pathogens associated with both sporadic illness and outbreaks of enteric disease. While it is known that cattle are reservoirs of VTEC, little is known about the genomic variation of VTEC in cattle, and whether the variation in genomes reported for human outbreak strains is consistent with individual animal or group/herd sources of infection. A previous study of VTEC prevalence identified serotypes carried persistently by three consecutive cohorts of heifers within a closed herd of cattle. This present study aimed to (i) determine whether the genomic relatedness of bovine isolates is similar to that reported for human strains associated with single source outbreaks, (ii) estimate the rates of genome change among dominant serotypes over time within a cattle herd, and (iii) identify genomic features of serotypes associated with persistence in cattle. Illumina MiSeq genome sequencing and genotyping based on allelic and single nucleotide variations wanalyses identified accessory regions that were more prevalent in persistent serotypes (P≤0.05) than in sporadic serotypes. These results suggest that VTEC serotypes from a specific cattle population are highly clonal with a similar level of relatedness as human single-source outbreak-associated strains, but changes in the genome occur gradually over time. Additionally, elements in the accessory genomes may provide a selective advantage for persistence of VTEC within cattle herds.A Gram-negative, strictly aerobic, gliding motility, none-spore forming, yellow, rods bacterial strain, designated XS-5T, was isolated from rhizosphere soil of Suaeda salsa, in Tumd Right Banner, Inner Mongolia, PR China. A phylogenetic tree based on the 16S rRNA gene sequences and the phylogenomic tree both showed that strain XS-5T clustered with Flavobacterium beibuense F44-8T (shared 97.2 % of 16S rRNA gene similarity) and Flavobacterium rakeshii FCS-5T (97.6 %), and shared less then 96.0 % of 16S rRNA gene similarities with all other type strains. Strain XS-5T contained MK-6 as the major respiratory quinone. Its major polar lipids were phosphatidylethanolamine, an unidentified aminolipid and an unidentified lipid; and the major fatty acids were iso-C15 0, iso-C17 0 3-OH, C16 0, iso-C15 0 3-OH, Summed feature 3 (iso-C15 0 2-OH and/or C16 1 ω7c), and Summed feature 9 (iso-C17 1 ω9c and/or C16 0 10-methyl). The genome consisted of a 3 985 855 bp circular chromosome, with a G+C content of 37.9 mol%, predicting 3616 coding sequences genes, 45 tRNA genes and three rRNA operons. The average nucleotide identity, amino acid identity and digital DNA-DNA hybridization values of strain XS-5T to F. beibuense F44-8T and F. rakeshii FCS-5T were 79.2 and 79.2 %, 81.7 and 81.6 %, 22.3 and 22.2 %, respectively. The results of phylogenetic, physiological and biochemical tests allowed the discrimination of strain XS-5T from its phylogenetic relatives. Flavobacterium alkalisoli sp. nov. is therefore proposed with strain XS-5T (=CGMCC 1.17077T=KCTC 72459T) as the type strain.Eight Gram-stain-positive, rod-shaped bacterial strains were isolated from faeces of Tibetan antelopes on the Tibet-Qinghai Plateau of China. Genomic sequence analysis showed that the strains belong to the genera Actinomyces (strains 299T and 340), Corynebacterium (strains 2184T, 2185, 2183T and 2189) and Oceanobacillus (strains 160T and 143), respectively, with a percentage of similarity for the 16S rRNA gene under the species threshold of 98.7 % except for strains 160T and 143 with Oceanobacillus arenosus CAU 1183T (98.8 %). The genome sizes (and genomic G+C contents) were 3.1 Mb (49.4 %), 2.5 Mb (64.9 %), 2.4 Mb (66.1 %) and 4.1 Mb (37.1 %) for the type strains 299T, 2183T, 2184T and 160T, respectively. Two sets of the overall genome relatedness index values between our isolates and their corresponding closely related species were under species thresholds (95 % for average nucleotide identity, and 70 % for digital DNA-DNA hybridization). These results, together with deeper genotypic, genomic, phenotypic and biochemical analyses, indicate that these eight isolates should be classified as representing four novel species.
