Po.lar.i.bac'ter. N.L. adj. polaris pertaining to the geographic poles; N.L. masc. n. bacter from Gr. n. baktron rod or staff; N.L. masc. n. Polaribacter rod‐shaped bacteria from polar habitats. Bacteroidetes / Flavobacteriia / Flavobacteriales / Flavobacteriaceae / Polaribacter Rods , curved rods , or filaments . Cell size varies between 0.8 and 48 µm in length and 0.25 and 1.6 µm in diameter depending on species, growth medium, temperature, and physiological state of the culture. Nonmotile; some cells may have flagella, but motility has not been observed. Coccoid bodies often seen in ageing cultures. Gas vesicles are produced by some species . Gram‐stain‐negative. Heterotrophic. Aerobic . Psychrophilic or mesophilic . Organisms grow well in marine media or media that have been supplemented with NaCl. Organisms produce acid from a variety of carbohydrates. Starch is hydrolyzed. Cells can grow on yeast extract. Colonies produce yellow, orange, salmon, or pink non‐diffusible pigments that are not flexirubins. Some strains produce rhodopsin pigments that stimulate growth in presence of light. Some strains have been isolated from polar marine and sea ice environments and grow at temperatures of 10°C or lower. All strains have been isolated from marine habitats . DNA G + C content ( mol %): 30–33. Type species : Polaribacter filamentus Gosink, Woese and Staley 1998, 232 VP .
