Hominimerdicola alba

Hominimerdicola alba 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 Hominimerdicola alba rather than just read about it. In short: Hominimerdicola alba is an obligately anaerobic, Gram-positive, cellulose-degrading bacterium in the family Oscillospiraceae. It was originally isolated from the rumen of cattle and described as Ruminococcus albus.

Key takeaways

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

Reference excerpt

Hominimerdicola alba is an obligately anaerobic, Gram-positive, cellulose-degrading bacterium in the family Oscillospiraceae. It was originally isolated from the rumen of cattle and described as Ruminococcus albus. The species was transferred to the genus Hominimerdicola in 2026.

Taxonomy The species was described by Robert Hungate in 1957 as Ruminococcus albus. In 2026, phylogenetic, genomic and phenotypic analyses supported its transfer to Hominimerdicola as Hominimerdicola alba. LPSN treats H. alba as the correct name and R. albus as a homotypic synonym. The specific epithet alba is the feminine form of the Latin adjective albus, meaning white.

Ecology and metabolism H. alba is an important plant-fibre-degrading member of the rumen microbiota. It produces enzymes that hydrolyze plant cell-wall polysaccharides, including cellulose and hemicellulose. Fermentation of cellulose, cellobiose and glucose produces acetate, ethanol, carbon dioxide and molecular hydrogen. The species has also been used as a model for interspecies hydrogen transfer. When grown with the hydrogen-consuming bacterium Wolinella succinogenes, removal of hydrogen changes its fermentation products and increases its growth yield.

Worked examples

Example 1 — a first encounter with Hominimerdicola alba

Start with the simplest possible case. Write down what Hominimerdicola alba 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 Hominimerdicola alba 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 Hominimerdicola alba 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 Hominimerdicola alba

In research: Hominimerdicola alba 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 Hominimerdicola alba 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: Hominimerdicola alba is common in secondary-school and first-year university syllabi. It links to neighbouring topics Anaerobes, Bacteria described in 1957, Gut flora bacteria, so understanding it makes those chapters shorter.
In everyday life: Look for Hominimerdicola alba 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.
