Holdemanella porci

Holdemanella porci 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 Holdemanella porci rather than just read about it. In short: Holdemanella porci is a species of Gram-positive, strictly anaerobic bacteria in the family Erysipelotrichaceae. It was first isolated from the gastrointestinal tract of pigs and described in 2020 as part of a large-scale effort to culture and characterize pig gut microbiota.

Key takeaways

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

Reference excerpt

Holdemanella porci is a species of Gram-positive, strictly anaerobic bacteria in the family Erysipelotrichaceae. It was first isolated from the gastrointestinal tract of pigs and described in 2020 as part of a large-scale effort to culture and characterize pig gut microbiota.

Morphology and physiology Holdemanella porci is characterized by:

Cell morphology: Gram-positive rods, non-spore-forming Oxygen requirement: Strictly anaerobic Metabolism: Fermentative, with the production of short-chain fatty acids

Isolation and habitat Holdemanella porci was isolated from the feces of a healthy 37-week-old pig in Kranzberg, Bavaria, Germany. The species is a member of the normal gut microbiota in pigs and is believed to play a role in carbohydrate fermentation and fiber degradation.

Worked examples

Example 1 — a first encounter with Holdemanella porci

Start with the simplest possible case. Write down what Holdemanella porci 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 Holdemanella porci 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 Holdemanella porci 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 Holdemanella porci

In research: Holdemanella porci 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 Holdemanella porci 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: Holdemanella porci is common in secondary-school and first-year university syllabi. It links to neighbouring topics Anaerobes, Bacteria described in 2021, Erysipelotrichales, so understanding it makes those chapters shorter.
In everyday life: Look for Holdemanella porci 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.
