A Gram stain-negative, aerobic, non-motile, short, rod-shaped bacterial strain CAU 1482 was isolated from coal mine wastewater in Hongcheon, Korea. It grew well at 30 °C, pH 8.5, 2% NaCl (w/v). 16S rRNA-based phylogeny indicated that CAU 1482 forms a distinct lineage within Aureimonas with high similarity to Aureimonas frigidaquae CW5 (98.2%), Aureimonas altamirensis S21B (98.0%), and Aureimonas glaciei B5-2 (96.3%). The predominant cellular fatty acids were C 2-OH, C, C ω7c, and/or C ω6c (summed feature 8), with Q-10 as the major isoprenoid quinone. The polar lipid profile comprised diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, two unidentified aminolipids, and three unidentified lipids. The 3.9-Mb genome included 8 contigs and 3599 protein-coding genes with a 56.7 mol% G + C content. Average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) values between strain CAU 1482 and closely related strains of A. frigidaquae CW5 and A. altamirensis S21B were 72.2‒72.4% and 18.7‒18.8%, respectively. These phenotypic, chemotaxonomic, and phylogenetic data support CAU 1482 as a novel Aureimonas species, for which the name Aureimonas fodinaquatilis sp. nov. is proposed. The type strain is CAU 1482 (= KCTC 62995 = NBRC 113692).
