Strain A8-7T was aerobic, heterotrophic and positive for catalase and oxidase. It grew at 20–37 °C (optimum 30 °C) and pH 5.5–10.5 (optimum pH 7.5) and in the presence of 0–3 % (w/v) NaCl. It formed pink-pigmented, smooth and circular colonies, 1–2 mm in diameter, on R3A-V agar plates after incubation at 30 °C for 3 days. Cells of strain A8-7T were rods, 0.2–0.4 μm wide and 1.6–4.0 μm long. The major fatty acids (>10 %) were iso-C15 : 0 (40.3 %) and summed feature 3 (C16 : 1 ω7c and/or iso-C15 : 0 2-OH; 12.1 %). The menaquinone was MK-7. The DNA G+C content was 43 mol% (T m). Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain A8-7T was phylogenetically related to members of the genus Algoriphagus, with sequence similarities of 92.6–95.2 %, the highest sequence similarity being to the sequence from Algoriphagus mannitolivorans IMSNU 14012T. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain A8-7T was considered to represent a novel species of the genus Algoriphagus, for which the name Algoriphagus aquatilis sp. nov. is proposed. The type strain is A8-7T (=CGMCC 1.7030T =NBRC 104237T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.005215-0
