Glaciecola polaris [2]

Paraglaciecola polaris(Glaciecola polaris) is a strictly aerobic and facultative oligotrophic bacterium from the genus of Paraglaciecola which has been isolated from seawater from the Arctic Ocean. [2] [1] [4] [5] [6]

Structure

It is gram negative, rod shaped and motile with the distinct characteristics of budding and peritrichous prosthecae. Budding can occur on the surface of the cell and/or on the prosthecae. The presence of the branched prosthecae, has an increased surface to volume ratio, so that it can maximize nutrient uptake, due to the low nutrient availability in the polar seas. Lastly, G. polaris has a fatty acid profile similar to other genera to include Alteromonas, Pseudoalteromonas and Glaciecola. [7]

Genetics

The 16S rRNA gene shows a 98% similarity to Glaciocolamesophila. It has a G+C content of 44.1 mol% and genome size of 5.24 Mb. [8]

Metabolism

The Arctic species can be cultured on Marine agar and R2A agar with NaCl. It grows between 5 °C - 37 °C and up to 10% NaCl. [6] It is chemoheterotrophic and can utilize a number of nutrient sources including, but not limited to, glucose, mannitol, cellobiose, sucrose, maltose, galactose, fructose, trehalose, mannose, acetate, glycogen, dextrin, lactate, propionate, glutamate, and malate In addition, it hydrolyzes egg yolk, starch, aesculin, and DNA, but does not reduce nitrate.

Polaribacter is a genus in the family Flavobacteriaceae. They are gram-negative, aerobic bacteria that can be heterotrophic, psychrophilic or mesophilic. Most species are non-motile and species range from ovoid to rod-shaped. Polaribacter forms yellow- to orange-pigmented colonies. They have been mostly adapted to cool marine ecosystems, and their optimal growth range is at a temperature between 10 and 32 °C and at a pH of 7.0 to 8.0. They are oxidase and catalase-positive and are able to grow using carbohydrates, amino acids, and organic acids.
