Summary
A novel bacterial strain, Tenacibaculuminsulae sp. nov., was identified from a South Korean tidal flat. This Gram-negative bacterium represents a new species within the Tenacibaculum genus, distinct from known relatives.
Area of Science:
- Microbiology
- Bacterial Taxonomy
- Marine Biology
Background:
- The genus Tenacibaculum comprises marine bacteria with implications in aquatic ecosystems.
- Accurate classification of novel bacterial isolates is crucial for understanding microbial diversity and ecological roles.
Purpose of the Study:
- To characterize and classify a newly isolated bacterial strain, JDTF-31T, from a marine environment.
- To determine if JDTF-31T represents a novel species within the genus Tenacibaculum.
Main Methods:
- Isolation and cultivation of strain JDTF-31T from a tidal flat.
- Phylogenetic analysis using 16S rRNA gene sequences.
- Determination of chemotaxonomic properties (fatty acids, menaquinone, polar lipids).
- DNA G+C content and DNA-DNA hybridization analyses.
Main Results:
- Strain JDTF-31T is a Gram-stain-negative, aerobic, non-motile, non-spore-forming bacterium.
- Phylogenetic analysis placed JDTF-31T within the Tenacibaculum genus, closely related to Tenacibaculum soleae.
- Distinct chemotaxonomic profiles and low DNA-DNA relatedness (16-27%) confirmed its novelty.
- Optimal growth at 25°C and 2.0% NaCl.
Conclusions:
- Strain JDTF-31T exhibits unique phenotypic, phylogenetic, and genetic characteristics.
- The data support the designation of JDTF-31T as a new species, Tenacibaculuminsulae sp. nov.
- This finding expands the known diversity within the Tenacibaculum genus.

Spirochetes, unique bacteria in the phylum Spirochaetes, are gram-negative, motile, tightly coiled, slender, and flexible. They inhabit aquatic sediments and animals, with some causing diseases like syphilis. Spirochetes are classified into eight genera based on habitat, pathogenicity, phylogeny, and characteristics.Their distinctive motility arises from endoflagella, located within the cell’s periplasm. These endoflagella anchor at the cell poles and extend along the cell length, encased...

Archaeal surface appendages are highly specialized structures essential for environmental adaptation, encompassing roles in adhesion, biofilm formation, and motility. Among these appendages, pili and archaella stand out for their distinct morphologies and functionalities, enabling archaea to thrive in diverse and often extreme environments.Pili: Adhesion and Biofilm FormationPili are filamentous structures assembled from pilin protein subunits, primarily contributing to adhesion and biofilm...

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...

Excavata is a diverse group of protists that includes both chemoorganotrophic and phototrophic species, with some thriving in anaerobic environments. Among the key groups within Excavata are diplomonads and parabasalids, which are flagellated protists that lack mitochondria and chloroplasts. These microorganisms typically inhabit anoxic environments, such as the intestines of animals, where they exist either symbiotically or as parasites, relying on fermentation for energy production. Some...

The phylum Tenericutes, which includes the single class Mollicutes, comprises bacteria that lack cell walls. The term "Mollicutes" derives from the Latin word mollis, meaning "soft." These organisms are among the smallest known and are commonly referred to as mycoplasmas due to the prominence of the genus Mycoplasma, which includes well-known human pathogens. Despite their inability to stain gram-positively (a result of their lack of cell walls), mycoplasmas are phylogenetically related to the...

Coryneform bacteria are gram-positive, aerobic, nonmotile rods that exhibit irregular, club-shaped, or V-shaped arrangements. Their V-shape results from snapping division, where the inner cell wall layer forms the cross-wall, while the outer layer remains intact until it ruptures on one side, causing the daughter cells to bend away.The primary genera are Corynebacterium and Arthrobacter. Corynebacterium includes diverse species, ranging from saprophytes to pathogens like Corynebacterium...
