<i>Youngimonas ophiurae</i> sp. nov., a Quorum-Quenching Marine Bacterium Isolated from a Brittle Star in the South China Sea, and Reclassification of <i>Lutimaribacter litoralis</i> as <i>Youngimonas litoralis</i> comb. nov.

ABSTRACT: Two novel bacterial strains, designated S70^T and S69A, were isolated from a marine brittle star collected in the South China Sea. These strains are Gram-stain-negative, non-motile, aerobic, and rod-shaped. A phylogenomic analysis indicated that strains S70^T and S69A formed a distinct branch with Youngimonas vesicularis CC-AMW-E^T and Lutimaribacter litoralis JCM 17792^T. The DNA G+C content of both strains was 61.5%. The digital DNA-DNA hybridization values with the closest relatives were 21.8, and 21.2%, respectively. Furthermore, the average nucleotide identity (ANIb) values between strain S70^T and these two reference strains were 74.9% and 74.6%, respectively, both well below the 95-96% threshold for dividing prokaryotic
