Tractidigestivibacter scatoligenes

Tractidigestivibacter scatoligenes 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 Tractidigestivibacter scatoligenes rather than just read about it. In short: Tractidigestivibacter scatoligenes is a Gram-positive, saccharolytic, non-spore-forming, strictly anaerobic, and non-motile bacterium in the family Atopobiaceae. It was originally isolated from pig feces in Denmark and is the type species of the genus Tractidigestivibacter.

Key takeaways

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

Reference excerpt

Tractidigestivibacter scatoligenes is a Gram-positive, saccharolytic, non-spore-forming, strictly anaerobic, and non-motile bacterium in the family Atopobiaceae. It was originally isolated from pig feces in Denmark and is the type species of the genus Tractidigestivibacter.

Taxonomy The species was originally described in 2015 as Olsenella scatoligenes. A phylogenomic revision of the family Atopobiaceae in 2021 transferred it to the newly established genus Tractidigestivibacter, resulting in the combination Tractidigestivibacter scatoligenes. The List of Prokaryotic names with Standing in Nomenclature recognizes this as the correct name and treats Olsenella scatoligenes as a homotypic synonym. The specific epithet scatoligenes means “skatole-producing”, referring to the bacterium's production of skatole.

Characteristics Cells are Gram-positive, strictly anaerobic, non-motile, non-spore-forming coccobacilli. The species metabolizes indole-3-acetic acid to 3-methylindole (skatole) and produces 4-methylphenol (p-cresol) from p-hydroxyphenylacetic acid. Skatole is an important contributor to boar taint, an undesirable odour and flavour that can occur in pork from uncastrated male pigs.

Worked examples

Example 1 — a first encounter with Tractidigestivibacter scatoligenes

Start with the simplest possible case. Write down what Tractidigestivibacter scatoligenes 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 Tractidigestivibacter scatoligenes 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 Tractidigestivibacter scatoligenes 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 Tractidigestivibacter scatoligenes

In research: Tractidigestivibacter scatoligenes 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 Tractidigestivibacter scatoligenes 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: Tractidigestivibacter scatoligenes is common in secondary-school and first-year university syllabi. It links to neighbouring topics Actinomycetota stubs, Anaerobes, Bacteria described in 2015, so understanding it makes those chapters shorter.
In everyday life: Look for Tractidigestivibacter scatoligenes 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.
