Gordonibacter

Gordonibacter 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 Gordonibacter rather than just read about it. In short: Gordonibacter is a genus of Gram-positive, strictly anaerobic, rod-shaped bacteria in the family Eggerthellaceae. Members of the genus have been isolated from the human intestinal tract, and motility varies among species.

Key takeaways

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

Reference excerpt

Gordonibacter is a genus of Gram-positive, strictly anaerobic, rod-shaped bacteria in the family Eggerthellaceae. Members of the genus have been isolated from the human intestinal tract, and motility varies among species.

Characteristics The type strain of Gordonibacter pamelaeae was isolated from the colon of a patient with Crohn's disease. It is non-motile, whereas Gordonibacter urolithinfaciens and Gordonibacter faecis are motile. G. urolithinfaciens was originally isolated from human feces and can transform ellagic acid, a dietary polyphenol-derived compound, into urolithin metabolites. G. faecis, which was also isolated from human feces, converts ellagic acid into urolithin C.

Taxonomy G. pamelaeae is the type species of Gordonibacter. The generic name honours microbiologist Jeffrey I. Gordon and combines his surname with the Neo-Latin word bacter, meaning "rod".

Phylogeny The following phylogenomic tree is based on the bacterial tree from GTDB release R11-RS232, which was inferred from 120 single-copy marker proteins. GTDB placeholder species and taxa without validly published names are not shown.

Worked examples

Example 1 — a first encounter with Gordonibacter

Start with the simplest possible case. Write down what Gordonibacter 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 Gordonibacter 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 Gordonibacter 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 Gordonibacter

In research: Gordonibacter 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 Gordonibacter 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: Gordonibacter is common in secondary-school and first-year university syllabi. It links to neighbouring topics Actinomycetota, Anaerobes, Bacteria genera, so understanding it makes those chapters shorter.
In everyday life: Look for Gordonibacter 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.

Frequently asked questions

What is Gordonibacter in simple terms?

Why does Gordonibacter matter?

Because it connects several biology ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Gordonibacter?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
