Salinicola salarius is a Gram-negative, moderately halophilic, piezophilic proteobacterium that requires pressures of 102 MPa to grow.[1] The species was first isolated from a salt water sample from Anmyeondo, Korea and was formally described in 2007. S salarius cells are aerobic, Gram-negative, non-spore-forming rods (0.8–0.9x1.3–1.7 μm) that form yellow, smooth, translucent, circular colonies with entire edges. The oxidase- and catalase-positive cells are motile and possess lateral/polar flagella. Growth occurs at 10–45 °C (optimally at 25–30 °C) and at pH 5–10 (optimum pH 7–8). The strain is able to grow at salinities between 0 and 25% NaCl (optimum 10–20% NaCl).[2][3]

S.I. Paul et al. (2021)[2] isolated and identified salt tolerant Salinicola salarius from marine sponges (Niphates erecta, Hemimycale columella) of the Saint Martin's Island Area of the Bay of Bengal, Bangladesh.
