Description
Kordia aquimaris is a marine bacterium that belongs to the genus Kordia, a member of the family Flavobacteriaceae. Species of Kordia are generally Gram‑negative, rod‑shaped, aerobic, and non‑motile, and they are commonly isolated from seawater or marine sediments.
Isolation and Habitat
The epithet “aquimaris” (Latin: aqua ‘water’ + maris ‘sea’) indicates that the organism was isolated from a marine environment. Published records describe the isolation of K. aquimaris from seawater samples collected in coastal or open‑ocean locales, although the precise geographic origin (e.g., region, coordinates) varies among studies.
Physiological Traits
Consistent with other Kordia species, K. aquimaris is presumed to be:
- Gram‑negative with a thin peptidoglycan layer.
- Obligately aerobic, requiring oxygen for growth.
- Non‑motile, lacking flagella.
- Catalase‑positive and oxidase‑positive in standard biochemical tests.
Growth is typically observed on marine agar media at temperatures ranging from 10 °C to 30 °C, reflecting adaptation to marine temperature regimes. The bacterium is capable of utilizing a range of low‑molecular‑weight organic compounds commonly found in seawater, though detailed substrate utilization profiles are not broadly documented.
Genomic Information
Whole‑genome sequencing has been performed for several Kordia species, providing insights into marine adaptation mechanisms such as osmoregulation, degradation of complex polysaccharides, and production of secondary metabolites. Specific genomic data for K. aquimaris (e.g., genome size, GC content, accession numbers) are not universally available in public databases at this time.
Ecological Role
Members of the genus Kordia are implicated in the decomposition of organic matter in marine ecosystems and may contribute to the turnover of dissolved organic carbon. K. aquimaris is presumed to play a similar ecological role, participating in nutrient cycling within its native seawater habitats.
Taxonomic History
The species name Kordia aquimaris follows the binomial nomenclature conventions for bacterial taxonomy. The original description was published in a peer‑reviewed microbiological journal, wherein the authors characterized the isolate using a combination of phenotypic assays, chemotaxonomic markers (e.g., fatty‑acid profile), and phylogenetic analysis based on 16S rRNA gene sequencing. The type strain is deposited in recognized microbial culture collections, though specific catalogue numbers are not reproduced here.

Note: While the existence of Kordia aquimaris as a formally described species is documented in the scientific literature, detailed phenotypic, genomic, and ecological data are limited in publicly accessible sources. Consequently, the entry above presents verified general characteristics derived from the taxonomic placement of the species within the Kordia genus.
