Paraglaciecola polaris

Paraglaciecola polaris is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Paraglaciecola polaris rather than just read about it. In short: Paraglaciecola polaris (syn. 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.

Key takeaways

Paraglaciecola polaris belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Paraglaciecola polaris to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Paraglaciecola polaris from memory before moving on to harder problems.

Reference excerpt

Paraglaciecola polaris (syn. 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.

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.

Genetics The 16S rRNA gene shows a 98% similarity to Glaciocola mesophila. It has a G+C content of 44.1 mol% and genome size of 5.24 Mb.

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. 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.

Worked examples

Example 1 — a first encounter with Paraglaciecola polaris

Start with the simplest possible case. Write down what Paraglaciecola polaris claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Paraglaciecola polaris before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Paraglaciecola polaris ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Paraglaciecola polaris

In research: Paraglaciecola polaris appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Paraglaciecola polaris in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Paraglaciecola polaris is common in secondary-school and first-year university syllabi. It links to neighbouring topics Alteromonadales, Alteromonadales stubs, Bacteria described in 2004, so understanding it makes those chapters shorter.
In everyday life: Look for Paraglaciecola polaris outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
