Halomonas desiderata

Halomonas desiderata is a earth 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 Halomonas desiderata rather than just read about it. In short: Halomonas desiderata is an alkaliphilic, halotolerant and denitrifying bacterium first isolated from a municipal sewage works. References Further reading Oren, Aharon (2002).

Key takeaways

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

Worked examples

Example 1 — a first encounter with Halomonas desiderata

Start with the simplest possible case. Write down what Halomonas desiderata claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth 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 Halomonas desiderata 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 Halomonas desiderata 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 Halomonas desiderata

In research: Halomonas desiderata appears in earth 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 Halomonas desiderata 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: Halomonas desiderata is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bacteria described in 1997, Gram-negative bacteria, Halophiles, so understanding it makes those chapters shorter.
In everyday life: Look for Halomonas desiderata 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.
