A novel yellow-pigmented bacterium, Salegentibacter flavus, was discovered in the Sea of Japan. This non-motile, Gram-negative organism exhibits unique growth requirements and biochemical properties, expanding the Salegentibacter genus.

Area of Science:

  • Microbiology
  • Bacteriology
  • Marine Biology

Background:

  • Isolation of novel microorganisms from marine environments is crucial for understanding biodiversity.
  • Marine sediments are rich sources of unique bacterial species with potential biotechnological applications.

Purpose of the Study:

  • To characterize a novel yellow-pigmented bacterium isolated from marine sediment.
  • To determine the taxonomic placement of the novel isolate within the genus Salegentibacter.

Main Methods:

  • Isolation and cultivation of bacteria from marine sediment.
  • Physicochemical characterization including growth conditions, temperature, salinity, and pH.
  • Biochemical tests for enzyme activities (starch, gelatin, casein, agar, Tween 80 hydrolysis).

  • Analysis of cellular fatty acid composition.
  • DNA G+C content determination.
  • 16S rRNA gene sequencing for phylogenetic analysis.

    • Main Results:

    • A yellow-pigmented, non-motile, Gram-negative bacterium (strain Fg 69T) was isolated.
    • Optimal growth occurred at 10-35°C, neutrophilic conditions, and 3-10% NaCl.
    • Weak hydrolysis of starch, gelatin, and Tween 80 was observed.
    • Predominant fatty acids included iso-C15:0, anteiso-C15:0, C15:0, iso-C15:1, iso-C16:0, C16:0, and C16:1ω7.
    • DNA G+C content was 40.4 mol%.
    • 16S rRNA gene sequence analysis indicated it belonged to the genus Salegentibacter but was distinct from known species (94-95% similarity).

    Conclusions:

    • Strain Fg 69T represents a novel species within the genus Salegentibacter.
    • The proposed name for the novel species is Salegentibacter flavus sp. nov.
    • The type strain is Fg 69T (=KMM 6000T = CIP 107843T).
