COLWELLIA AQUAEMARIS
| Class: | Gamma Proteobacteria |
| Genus: | Colwellia |
| Species: | Colwellia aquaemaris |
| Description: | Cells are Gram-staining-negative, non-spore-forming, curved rods (0.4–0.6 µm wide× 1.0–2.0 µm long), motile by means of a single polar flagellum. Strictly heterotrophic, and facultatively anaerobic. Positive for oxidase and catalase activities. Colonies are 1–2 mm in diameter, beige, circular, flat and smooth on MA plates after incubation at 25 °C for 2 days. Growth occurs at 4–30 °C (optimum, 25 °C), at pH 5.5–10.0 (optimum, pH 6.5–7.5) and in the presence of 1–5 % (w/v) NaCl (optimum, 2 %); no growth occurs in the absence of NaCl. |
