Comamonas composti is a species of Gram‑negative bacteria within the genus Comamonas, family Comamonadaceae, order Burkholderiales, class Betaproteobacteria, phylum Pseudomonadota (formerly Proteobacteria).
Taxonomy
- Domain: Bacteria
- Phylum: Pseudomonadota
- Class: Betaproteobacteria
- Order: Burkholderiales
- Family: Comamonadaceae
- Genus: Comamonas
- Species: Comamonas composti
Discovery and isolation
The species was first described in 2015 following its isolation from a compost sample. The specific epithet composti reflects the source of isolation (compost). The type strain was deposited in internationally recognized culture collections for reference, though accession numbers are not provided here.
Morphology and physiology
- Cell shape: Rod‑shaped (bacilli)
- Gram reaction: Negative
- Oxygen requirement: Strictly aerobic
- Motility: Motile, typically via polar flagella
- Spore formation: Non‑spore‑forming
Biochemical characteristics
Comamonas composti oxidizes a range of organic substrates typical for members of the genus, including simple sugars and organic acids. It exhibits catalase and oxidase activity, consistent with other Comamonas species. Detailed phenotypic profiles are available in the original species description.
Ecological relevance
The isolation from compost suggests a role in the degradation of organic matter during composting processes. Members of the genus Comamonas are known for versatile metabolic capabilities, contributing to nutrient cycling in soil and waste‑treatment environments.
Significance
While no specific pathogenicity has been reported for C. composti, its enzymatic activities may be of interest for biotechnological applications such as biodegradation or bioremediation. Further studies are required to elucidate its functional roles and potential utility.
