Main Results:

A novel ovoid to rod-shaped, Gram-negative bacterium, strain JA136(T), was isolated.
Strain JA136(T) is phototrophic, motile, and tolerates up to 4% NaCl.
Phylogenetic analysis placed strain JA136(T) within the Allochromatium genus, distinct from known species.
Highest 16S rRNA gene sequence similarity was observed with Allochromatium vinosum (97.0%).

Conclusions:

Strain JA136(T) represents a novel species, Allochromatium renukae sp. nov.
This discovery expands the known biodiversity of purple sulfur bacteria.
Allochromatium renukae contributes to the understanding of Gammaproteobacteria evolution.
