Veillonellaceae

Veillonellaceae 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 Veillonellaceae rather than just read about it. In short: The Veillonellaceae are a family of the Clostridia, formerly known as Acidaminococcaceae. Bacteria in this family are grouped together mainly based on genetic studies, which place them among the Bacillota.

Key takeaways

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

Reference excerpt

The Veillonellaceae are a family of the Clostridia, formerly known as Acidaminococcaceae. Bacteria in this family are grouped together mainly based on genetic studies, which place them among the Bacillota. Supporting this placement, several species are capable of forming endospores. However, they differ from most other Bacillota in having Gram-negative stains. The cell wall composition is peculiar. Members of this family are all obligate anaerobes, and occur in habitats such as rivers, lakes, and the intestines of vertebrates. They range from spherical forms, such as Megasphaera and Veillonella, to curved rods, as typified by the Selenomonads. Selenomonas has a characteristic crescent-shape, with flagella inserted on the concave side, while Sporomusa is similar but non-motile. Their names refer to this distinctive morphology: selene means moon, and musa means banana. The name Selenobacteria also refers to some this group. The description of this family was emended in 2010 and, together with the Acidaminococcaceae (familia nova, which means a newly coined taxa), it was placed in the order Selenomonadales (ordo novus) in the class Negativicutes (classis novus) of the phylum Bacillota.

Phylogeny The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) and National Center for Biotechnology Information (NCBI).

Worked examples

Example 1 — a first encounter with Veillonellaceae

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

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