A novel bacterial species, Caproiciproducens faecalis, was identified from cow feces. This obligately anaerobic, Gram-positive bacterium expands the known diversity within the Oscillospiraceae family.
Area of Science:
- Microbiology
- Bacteriology
- Genomics
Background:
- The family Oscillospiraceae comprises anaerobic bacteria found in various environments.
- The genus Caproiciproducens currently includes species isolated from animal gastrointestinal tracts.
Purpose of the Study:
- To characterize a novel bacterial isolate from cow feces.
- To determine the taxonomic placement of the novel strain within the genus Caproiciproducens.
Main Methods:
- Phenotypic, biochemical, and chemotaxonomic analyses were performed.
- 16S rRNA gene sequencing was used for phylogenetic analysis.
- Average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) were calculated.
Main Results:
- Strain AGMB10547T is an obligately anaerobic, non-motile, Gram-positive, rod-shaped bacterium.
- Phylogenetic analysis based on 16S rRNA gene sequences showed highest similarity (96.9%) to Caproiciproducens galactitolivorans BS-1T.
- ANI (75.5%) and dDDH (19.2%) values confirmed that strain AGMB10547T represents a distinct species.
Conclusions:
- Strain AGMB10547T represents a novel species of the genus Caproiciproducens.
- The proposed name for the novel species is Caproiciproducens faecalis sp. nov.
- This discovery contributes to the understanding of bacterial diversity in ruminant gastrointestinal tracts.
