Victivallis

Victivallis 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 Victivallis rather than just read about it. In short: Victivallis is a genus of strictly anaerobic bacteria, the only genus in the family Victivallaceae and order Victivallales. The genus contains two species with validly published names: Victivallis lenta and the type species, Victivallis vadensis.

Key takeaways

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

Reference excerpt

Victivallis is a genus of strictly anaerobic bacteria, the only genus in the family Victivallaceae and order Victivallales. The genus contains two species with validly published names: Victivallis lenta and the type species, Victivallis vadensis. Both species have been isolated from mammalian intestinal-associated samples.

Characteristics The type strain of V. vadensis was isolated from human feces. Its cells are non-motile, coccoid, and surrounded by an extracellular slime layer. It grows strictly anaerobically by fermenting sugars, including cellobiose. During growth on glucose, it produces acetate, ethanol, and molecular hydrogen. Victivallis lenta was isolated from the feces of a minipig. Under anaerobic culture conditions, it consumed glucose and produced primarily acetate, together with smaller amounts of lactate and formate. Genomic analysis identified starch, cellulose, and fructan as potential carbohydrate substrates.

Taxonomy and etymology Victivallis is the nomenclatural type genus of both the family Victivallaceae and the order Victivallales. The generic name combines the Latin words victus, meaning food, and vallis, meaning valley. It refers to the Wageningen “Food Valley” region of the Netherlands, where the type species was studied.

Worked examples

Example 1 — a first encounter with Victivallis

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

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

Why does Victivallis 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 Victivallis?

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.
