Wolinella

Wolinella 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 Wolinella rather than just read about it. In short: The genus Wolinella is a member of the Campylobacterales order of Bacteria. The order Campylobacterales includes human pathogens such as Helicobacter pylori and Campylobacter jejuni.

Key takeaways

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

Reference excerpt

The genus Wolinella is a member of the Campylobacterales order of Bacteria. The order Campylobacterales includes human pathogens such as Helicobacter pylori and Campylobacter jejuni.

Strains The only publicly available strain of Wolinella is Wolinella succinogenes DSM 1740 (ATCC 29543). The original isolation of this organism was done by M. J. Wolin, E. A. Wolin and N. J. Jacobs at the University of Illinois. This original isolation was done from bovine rumen fluid and was somewhat serendipitous as the researchers were intending to isolate methanogenic organisms. This bacterium was originally classified as Vibrio succinogenes, but was reclassified in 1981 to Wolinella succinogenes by A. C. R. Tanner et al. Strains of Wolinella have been isolated from feline and canine oral cavities. Only one strain is currently published with Candidatus status: Candidatus Wolinella africanus. This strain was isolated from the upper digestive tracts of a Venezuelan volunteer.

Characteristics Wolinella species are Gram-negative.

Metabolism Some of the research done on Wolinella succinogenes includes its mutualistic relationship with hydrogen-producing organisms, including Ruminococcus albus. Their relationship is based on interspecies hydrogen transfer. Wolinella succinogenes molecular hydrogen using a fumarate reductase, producing succinate.

Worked examples

Example 1 — a first encounter with Wolinella

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

In research: Wolinella 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 Wolinella 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: Wolinella is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bacteria described in 1981, Bacteria genera, Campylobacterota, so understanding it makes those chapters shorter.
In everyday life: Look for Wolinella 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 Wolinella in simple terms?

The genus Wolinella is a member of the Campylobacterales order of Bacteria. The order Campylobacterales includes human pathogens such as Helicobacter pylori and Campylobacter jejuni.

Why does Wolinella 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 Wolinella?

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.

What does this page cover?

It gives you a compact reference excerpt plus original lgStudy explanations, examples, applications and study material on Wolinella.
