Polaribacter irgensii

Polaribacter irgensii 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 Polaribacter irgensii rather than just read about it. In short: Polaribacter irgensii is a species of gram-negative, gas vacuolate polar marine bacteria. The species was first isolated from sea ice and water from the Arctic and the Antarctic.

Key takeaways

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

Reference excerpt

Polaribacter irgensii is a species of gram-negative, gas vacuolate polar marine bacteria. The species was first isolated from sea ice and water from the Arctic and the Antarctic. Its type strain is ATCC 700398. The species was validly published in 1998.

Worked examples

Example 1 — a first encounter with Polaribacter irgensii

Start with the simplest possible case. Write down what Polaribacter irgensii 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 Polaribacter irgensii 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 Polaribacter irgensii 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 Polaribacter irgensii

In research: Polaribacter irgensii 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 Polaribacter irgensii 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: Polaribacter irgensii is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bacteria described in 1998, Flavobacteria, Flavobacteria stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Polaribacter irgensii 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.
