Members of the genus are widely distributed and produce various polysaccharide-degrading enzymes. Many species in the genus have been isolated and characterized. However, few studies have focused on marine isolates or fish pathogens, and in-depth genomic analyses, particularly comparative analyses of isolates from different habitat types, are lacking.

The wetland is an important ecosystem for purifying pollutants and circulating nutrients. Numerous microorganisms contribute to maintaining this function. We obtained Flavobacterium enshiense R6S-5-6 which was isolated from Ungok (Ramsar) Wetland and conducted whole-genome sequencing to investigate what contribution R6S-5-6 could make to the wetland community.

Tidal flat microbes play an important ecological role by removing organic pollutants and providing an energy source. However, bacteria isolated from tidal flats and their genomes have been scarcely reported, making it difficult to elucidate which genes and pathways are potentially involved in the above roles. In this study, strain BSSL-CR3, the third reported species among the tidal flat Flavobacterium was analyzed using whole-genome sequencing to investigate its adaptability and functionality in tidal flats.

Strain JK7-1 isolated from marine sediment collected from Jeju Island of South Korea was strictly aerobic, Gram-stain-negative, catalase-positive, oxidase-positive, motile, and rod-shaped bacterium that is circular and convex with white pigment. Strain JK7-1 could grow at 10-30 °C and pH 6-9 with 1-6% (w/v) NaCl. Phylogenetic analysis based on its 16S rRNA gene sequence indicated that strain JK7-1 belonged to genus Sulfitobacter, sharing high sequence similarities with Sulfitobacter undariae W-BA2 (97.

Here, we report the complete genome sequence of Flavobacterium sediminilitoris YSM-43, isolated from a tidal flat in Yeosu, Republic of Korea. The whole genome consists of one circular chromosome of 3,913,692 bp. A total of 3,599 genes were predicted, comprising 3,537 coding DNA sequences (CDSs), 50 tRNAs, 9 rRNAs, and 3 noncoding RNAs (ncRNAs).

This study investigated the factors that cause job stress among male flight attendants in a female-dominated airline organization, as well as the impact of job stress on their mental health and turnover intention. It also attempted to determine whether perceived family support, perceived organizational support, and job positions had moderating effects on male flight attendants' job stress. Six job stress factors were identified through focus group interviews and a literature review.

Article Synopsis
  • A new Gram-stain-negative bacterium called P2-65 was discovered in Moonsan stream water, Korea, notable for being rod-shaped, aerobic, and non-motile.
  • The bacterium grows optimally at temperatures of 25-30 °C, with a pH range of 7.0-7.5 and can tolerate up to 3.0% NaCl.
  • Genetic analysis revealed P2-65 is closely related to existing Flavobacterium species but distinct enough to propose it as a new species, named Flavobacterium inviolabile, with the type strain designated as P2-65.
