Pseu.do.al.te.ro.mo' nas . Gr. adj. pseudes false; M.L. n. Alteromonas the genus Alteromonas M.L. n. Pseudoalteromonas false Alteromonas . Proteobacteria / Gammaproteobacteria / Alteromonadales / Alteromonadaceae / Pseudoalteromonas Straight rods , approximately 1 × 2–3 µm, occurring singly or in pairs. Do not form spores or cysts. Do not accumulate poly‐β‐hydroxybutyrate. Nonbioluminescent. Gram negative. Motile by means of a single polar flagellum , either unsheathed or sheathed. Colonies are nonpigmented or pigmented. Chemoheterotrophic. Aerobic, possessing a strictly respiratory type of metabolism with oxygen as the terminal electron acceptor. No growth occurs anaerobically. A constitutive arginine dihydrolase system is usually absent. One species ( P. denitrificans ) is able to denitrify. Utilize a range of carbon substrates, including carbohydrates, alcohols, organic acids, and amino acids. Form gelatinase and lipase. Ammonia serves as a nitrogen source. Amino acids may be required by some strains for growth. Requires Na + ions for growth . Mostly psychrotolerant, with growth occurring between 0 and 40°C. Several species produce autotoxic antibiotic compounds. Isolated from seawater, sediment, sea ice, surfaces of stones, marine algae, marine invertebrates, and salted foods. The major quinone is ubiquinone‐8 (Q‐8). Major fatty acids are C 16:0 , C 16:1 ω7c , C 17:1 ω8c , and C 18:1 ω7c . Member of the order Alteromonadales , family Alteromonadaceae , in the Gammaproteobacteria . The mol % G + C of the DNA is : 38–48 ( T m ). Type species : Pseudoalteromonas haloplanktis (Zobell and Upham 1944) Gauthier, Gauthier and Christen 1995a, 759 ( Alteromonas haloplanktis (Zobell and Upham 1944) Reichelt and Baumann 1973a, 438; “ Vibrio haloplanktis ” Zobell and Upham 1944, 261.)
