Summary
A novel bacterium, Zeimonas sediminis FT117T, was isolated from mangrove sediment. Phylogenetic and genomic analyses confirm it represents a new species within the Zeimonas genus.
Area of Science:
- Microbiology
- Bacteriology
- Environmental Science
Background:
- Mangrove ecosystems harbor diverse microbial communities.
- Understanding bacterial diversity is crucial for ecological studies.
Purpose of the Study:
- To characterize a novel bacterial isolate from mangrove sediment.
- To determine the taxonomic placement of the isolate FT117T.
Main Methods:
- Isolation and cultivation of bacteria from mangrove sediment.
- 16S rRNA gene sequencing for phylogenetic analysis.
- Genomic analysis including ANI and dDDH.
- Fatty acid and polar lipid analysis.
Main Results:
- The isolate FT117T is a Gram-stain-negative, aerobic, motile rod.
- Phylogenetic analysis showed highest 16S rRNA gene sequence identity (98.7%) with *Zeimonas arvi*.
- Genomic analyses (ANI and dDDH) supported FT117T as a distinct species.
- Optimal growth conditions: 40°C, pH 8, and 0% NaCl.
Conclusions:
- FT117T represents a novel species, *Zeimonas sediminis* sp. nov.
- The proposed name reflects its isolation from sediment.
- This finding expands the known diversity within the *Zeimonas* genus.
