Atopic dermatitis (AD) is an inflammatory skin disease characterized by chronic inflammatory dermatitis with immunological manifestations. The aim of this study was to investigate the effects of polyphenol-containing Rubus coreanus...
Strain CAU 1641T was isolated from saltern collected in Ganghwa Island, Republic of Korea. The bacterium was an aerobic, Gram-negative, catalase-positive, oxidase-positive, motile, and rod-shaped bacterium. Cell of strain CAU 1641T could grow at 20–40°C and pH 6.0–9.0 with 1.0–3.0% (w/v) NaCl. Stain CAU 1641T shared high 16S rRNA gene sequence similarities with Defluviimonas aquaemixtae KCTC 42108T (98.0%), Defluviimonas denitrificans DSM 18921T (97.6%), and Defluviimonas aestuarii KACC 16442T (97.5%). Phylogenetic trees based on the 16S rRNA gene and the core-genome sequences indicated that strain CAU 1641T belonged to genus Defluviimonas. Strain CAU 1641T contained ubiquinone-10 (Q-10) as the sole respiratory quinone and and summed feature 8 (C18:1ω6c and/or C18:1ω7c) as the predominant fatty acid (86.1%). The pan-genome analysis indicated that the genomes of the strain CAU 1641T and 15 reference strains contain a small core genome. The Average Nucleotide Identity and digital DNA–DNA hybridization values among strain CAU 1641T and reference strains of the genus Defluviimonas were in the range of 77.6–78.8% and 21.1–22.1%, respectively. The genome of strain CAU 1641T has several genes of benzene degradation. The genomic G + C content was 66.6%. Based on polyphasic and genomic analyses, strain CAU 1641T represents a novel species of the genus Defluviimonas, for which the name Defluviimonas salinarum sp. nov., is proposed. The type strain is CAU 1641T ( = KCTC 92081T = MCCC 1K07180T).
A Gram-negative, non-motile, and reddish-orange-colored bacterium, designated CAU 1643T, was isolated from a mudflat collected in Ganghwa Island, Republic of Korea. The bacterium was found to grow optimally at 30°C, pH 9.0–9.5, and with 0–1% (w/v) NaCl. The highest 16S rRNA gene sequence similarities to the bacterium were Algoriphagus kandeliae XY-J91T (97.9%), Algoriphagus aquimaris F21T (97.1%), Algoriphagus formosus XAY3209T (97.0%) and Algoriphagus marincola DSM 16067T (96.2%). The DNA G + C content of the type strain was 40.35 mol%. The average nucleotide identity and digital DNA–DNA hybridisation values between strain CAU 1643T and the reference strains were below the threshold value for species demarcation. The predominant cellular fatty acids were iso-C15:0, iso-C17:0 3-OH and Summed Feature 9. The major respiratory quinone was menaquinone-7. The genome showed three putative biosynthetic gene clusters (BGCs) that are responsible for different secondary metabolites. Moreover, CAU 1643T contains 72 genes that encode carbohydrate-active enzymes. Based on phenotypic, phylogenetic, and chemotaxonomic evidence, strain CAU 1643T represents novel species in the genus Algoriphagus, for which the name Algoriphagus limi sp. nov. is proposed. The type strain is CAU 1643T ( = KCTC 92080T, = MCCC 1K07150T).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
