Psychrobacter proteolyticus

Psychrobacter proteolyticus 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 Psychrobacter proteolyticus rather than just read about it. In short: Psychrobacter proteolyticus is a species of bacteria first isolated from the Antarctic krill Euphausia superba. It excretes a cold-adapted metalloprotease.

Key takeaways

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

Reference excerpt

Psychrobacter proteolyticus is a species of bacteria first isolated from the Antarctic krill Euphausia superba. It excretes a cold-adapted metalloprotease. It is a strictly aerobic, strongly oxidase-positive, psychrotrophic, halotolerant, Gram-negative nonmotile coccobacillus; its type strain is CIP106830T (=DSM13887).

Worked examples

Example 1 — a first encounter with Psychrobacter proteolyticus

Start with the simplest possible case. Write down what Psychrobacter proteolyticus 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 Psychrobacter proteolyticus 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 Psychrobacter proteolyticus 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 Psychrobacter proteolyticus

In research: Psychrobacter proteolyticus 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 Psychrobacter proteolyticus 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: Psychrobacter proteolyticus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bacteria described in 2001, Gram-negative bacteria, Marine microorganisms, so understanding it makes those chapters shorter.
In everyday life: Look for Psychrobacter proteolyticus 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.
