The purpose of this study was to characterize strain SJW1-29^T and determine its taxonomic position as a potential new genus within the family <i>Spirosomaceae</i>. The strain grew within the range of 10-30 °C (optimum, 25 °C), pH 5.0-10.0 (optimum, 7.0), and 1-4% NaCl (optimum, 3%). Phylogenetic analysis based on the 16S rRNA gene revealed that strain SJW1-29^T belongs to the family <i>Spirosomaceae</i> and is closely related to <i>Persicitalea jodogahamensis</i> Shu-9-SY12-35C^T (91.3% similarity), <i>Rhabdobacter roseus</i> R491^T (90.6%), andMicroorganisms<i>Salmonirosea aquatica</i> gen. nov., sp. nov., a Novel Genus within the Family <i>Spirosomaceae</i>, Was Isolated from Brackish Water in the Republic of Korea.PMC11356934NNIBR202411032021003420003Jang SChoi ABaek KGoh Jfalse<i>Salmonirosea aquatica</i> gen. nov., sp. nov., a Novel Genus within the Family <i>Spirosomaceae</i>, Was Isolated from Brackish Water in the Republic of Korea.A Gram-stain-negative, obligately aerobic, non-motile, rod-shaped bacterial strain designated SJW1-29^T was isolated from brackish water samples collected from the Seomjin River, Republic of Korea.
