Geobacter psychrophilus

Geobacter psychrophilus is a science 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 Geobacter psychrophilus rather than just read about it. In short: Geobacter psychrophilus is a Fe(III)-reducing bacterium. It is Gram-negative, slightly curved, rod-shaped and motile via means of monotrichous flagella.

Key takeaways

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

Reference excerpt

Geobacter psychrophilus is a Fe(III)-reducing bacterium. It is Gram-negative, slightly curved, rod-shaped and motile via means of monotrichous flagella. Its type strain is P35T (=ATCC BAA-1013T =DSM 16674T =JCM 12644T).

Worked examples

Example 1 — a first encounter with Geobacter psychrophilus

Start with the simplest possible case. Write down what Geobacter psychrophilus claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Geobacter psychrophilus 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 Geobacter psychrophilus 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 Geobacter psychrophilus

In research: Geobacter psychrophilus appears in science 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 Geobacter psychrophilus 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: Geobacter psychrophilus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bacteria described in 2005, Bacteria stubs, Thermodesulfobacteriota, so understanding it makes those chapters shorter.
In everyday life: Look for Geobacter psychrophilus 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.
