Mediterraneibacter

Mediterraneibacter 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 Mediterraneibacter rather than just read about it. In short: Mediterraneibacter is a genus of anaerobic bacteria in the family Lachnospiraceae. Several species have been isolated from the human intestinal microbiota.

Key takeaways

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

Reference excerpt

Mediterraneibacter is a genus of anaerobic bacteria in the family Lachnospiraceae. Several species have been isolated from the human intestinal microbiota. The type species is Mediterraneibacter massiliensis, which was originally isolated from a human stool sample. It was described as Gram-positive, non-motile, non-spore-forming and coccobacillary. It is catalase-positive and oxidase-negative.

Taxonomy The genus name combines a reference to the Mediterranean Sea with the Neo-Latin word bacter, meaning a rod. The specific epithet of the type species, massiliensis, refers to Marseille, whose Latin name is Massilia. Several species now assigned to Mediterraneibacter were originally classified in the genera Ruminococcus or Clostridium. As of 2026, there are eight species with validly published and correct names.

Ecology and significance Mediterraneibacter gnavus, which is still widely discussed under its former name Ruminococcus gnavus, is a common member of the infant and adult human gut microbiota. Its interactions with the host vary among strains, and changes in its abundance have been associated with several intestinal and extra-intestinal disorders.

Worked examples

Example 1 — a first encounter with Mediterraneibacter

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

In research: Mediterraneibacter 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 Mediterraneibacter 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: Mediterraneibacter 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 Mediterraneibacter 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 Mediterraneibacter in simple terms?

Mediterraneibacter is a genus of anaerobic bacteria in the family Lachnospiraceae. Several species have been isolated from the human intestinal microbiota.

Why does Mediterraneibacter 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 Mediterraneibacter?

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.
