Polaribacter Gosink et al. 1998
General information
Description and emendation
Psychrophilic or psychrotrophic Gram-negative non-motile rods. Cell size varies between 2 and 48 µm in length and 0.25-1.6 µm in diameter depending on growth medium, temperature, and age of the culture. Coccoid bodies are often seen in ageing cultures. May form coils. Cells produce orange-, salmon- or pink-coloured pigments which are not flexirubins. Gas vesicles are produced in some strains. Some strains may be flagellated, but motility has never been observed in wet mounts. Aerobic. Cells grow well in media which contain NaCl. Cells produce acid from a number of carbohydrates. Starch is hydrolysed by these bacteria. Cells can grow on yeast extract and Casamino acids. G+C content range is 31-33 mol%. All strains have been isolated from polar marine environments and grow well at low temperatures.
1: Some species produce yellow coloured carotenoid pigments. The main polar lipids are phosphatidylethanolamine, two unidentified aminolipids and two unidentified lipids. The DNA G+C content is 28.6-33.2 mol%.
2: Some strains occur in temperate marine environments and are mesophilic. MK-6 is the only or major respiratory quinone in all analysed strains.
3: Major lipids in some species include phosphatidylethanolamine, two unidentified aminophospholipids, one unidentified lipid and one unidentified aminolipid. The DNA G+C content is 28.6-36.4 mol%.
