A total of 34 Halomonas strains were isolated from saline water in Anmyeondo, Korea. Ten of these strains, considered to belong to novel species, were subjected to a polyphasic taxonomic investigation. The strains were Gram-negative, moderately halophilic, motile and non-spore-forming rods that contained Q-9 as the predominant ubiquinone and C(18 : 1)omega7c, C(16 : 0) and either summed feature 4 (C(16 : 1)omega7c/C(15 : 0) iso 2-OH) or C(19 : 0) cyclo omega8c as the major fatty acids. Phylogenetic analysis, based on 16S rRNA gene sequencing, showed that the ten isolates formed four separate lineages in the genus Halomonas. Combined phenotypic data and DNA-DNA hybridization data supported the conclusion that they represent four novel species in the genus Halomonas, for which the names Halomonas gomseomensis sp. nov. (type strain M12(T)=KCTC 12662(T)=DSM 18042(T)), Halomonas janggokensis sp. nov. (type strain M24(T)=KCTC 12663(T)=DSM 18043(T)), Halomonas salaria sp. nov. (type strain M27(T)=KCTC 12664(T)=DSM 18044(T)) and Halomonas denitrificans sp. nov. (type strain M29(T)=KCTC 12665(T)=DSM 18045(T)) are proposed.

Two Gram-stain-negative, curved-rod-shaped, non-motile and aerobic bacteria W6 and I13 were isolated from marine sediment samples collected from Meishan Island located in the East China Sea. Catalase and oxidase activities and hydrolysis of Tween 40, 60 and 80 were positive for both strains, while nitrate reduction, indole production, methyl red reaction and HS production were negative. Phylogenetic analyses based on 16S rRNA and genome sequences revealed that strains W6 and I13 formed distinct phylogenetic lineages within the genera and , respectively.

A Gram-stain-negative, rod-shaped, non-motile, aerobic, light-yellow-pigmented bacterium, designated as strain Y10, was isolated from Lumnitzera racemosa leaf in Iriomote island mangrove forests in Japan. The 16S rRNA gene sequence analysis revealed that the isolate Y10 was affiliated with the family Flavobacteriaceae, and the sequence showed the highest sequence identity to that of Neptunitalea chrysea NBRC 110019 (97.2%) and others with below 96% sequence identity.

Background: : The metabolic by-product butyric acid of Gram-negative anaerobic bacteria can invoke pathological effects on periodontal cells resulting in inflammation and further destruction of periodontium. However, limited researches on the effects of butyric acid on cementoblasts were reported. Therefore, this study aimed to investigate the type of cell death in murine cementoblast (OCCM.

Glucose-stimulated insulin release from pancreatic β-cells is critical for maintaining blood glucose homeostasis. An abrupt increase in blood glucose concentration evokes a rapid and transient rise in insulin secretion followed by a prolonged, slower phase. A diminished first phase is one of the earliest indicators of β-cell dysfunction in individuals predisposed to develop type 2 diabetes.
