Romboutsia timonensis

Romboutsia timonensis 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 Romboutsia timonensis rather than just read about it. In short: Romboutsia timonensis is a species of Gram-positive, spore-forming, obligately anaerobic bacteria in the genus Romboutsia. The type strain was recovered from a colon lavage sample of a 63-year-old French man who presented with severe anaemia and melaena and underwent diagnostic colonoscopy at Hôpital de La Timone, Marseille.

Key takeaways

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

Reference excerpt

Romboutsia timonensis is a species of Gram-positive, spore-forming, obligately anaerobic bacteria in the genus Romboutsia. The type strain was recovered from a colon lavage sample of a 63-year-old French man who presented with severe anaemia and melaena and underwent diagnostic colonoscopy at Hôpital de La Timone, Marseille.

Description Cells are straight rods (≈ 0.7 × 2 μm), catalase-negative, and form subterminal endospores. On Columbia agar with 5% sheep blood, colonies are ≤ 1 mm, circular, opaque, and cream-coloured after 48 h at 37 °C under anoxic conditions. Growth occurs from 25–45 °C (optimum 37 °C) and tolerates up to 2% bile salts. The genomic G + C content is 28.3 mol%.

Etymology The species name timonensis refers to Hôpital de La Timone in Marseille, where the strain was first isolated.

Phylogeny Based on 16S rRNA gene similarity, R. timonensis is most closely related to Romboutsia ilealis (~94%). It clusters within the class Clostridia, apart from the polyphyletic "Clostridium" sensu lato group.

Ecology Metagenomic studies have detected Romboutsia species, including R. timonensis, at low abundance (<1%) in adult and elderly gut microbiomes.

Worked examples

Example 1 — a first encounter with Romboutsia timonensis

Start with the simplest possible case. Write down what Romboutsia timonensis 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 Romboutsia timonensis 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 Romboutsia timonensis 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 Romboutsia timonensis

In research: Romboutsia timonensis 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 Romboutsia timonensis 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: Romboutsia timonensis is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bacteria described in 2016, Clostridia stubs, Gut flora bacteria, so understanding it makes those chapters shorter.
In everyday life: Look for Romboutsia timonensis 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.
