Venenivibrio stagnispumantis

Venenivibrio stagnispumantis 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 Venenivibrio stagnispumantis rather than just read about it. In short: Venenivibrio stagnispumantis strain CP.B2 is the first microorganisms isolated from the terrestrial hot spring Champagne Pool (75 °C, pH 5.5) in Waiotapu, New Zealand. Morphology The cells are motile and slightly curved rods (1.04 to 1.56 μm long and 0.33 to 0.41 μm wide).

Key takeaways

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

Reference excerpt

Venenivibrio stagnispumantis strain CP.B2 is the first microorganisms isolated from the terrestrial hot spring Champagne Pool (75 °C, pH 5.5) in Waiotapu, New Zealand.

Morphology The cells are motile and slightly curved rods (1.04 to 1.56 μm long and 0.33 to 0.41 μm wide).

Growth conditions The novel bacterium is an obligate chemolithotroph capable of utilizing H2 as electron donor, O2 as corresponding electron acceptor and CO2 as carbon source. Venenivibrio stagnispumantis gains metabolic energy using the "Knallgas" reaction H2 + ½ O2 → H2O. For growth either elemental sulphur (S0) or thiosulfate (S2O32−) is required. Growth is observed under thermophilic conditions between 45 °C and 75 °C (optimum 70 °C), under moderate acidophilic conditions between pH 4.8 and 5.8 (optimum pH 5.4) and under microaerophilic conditions between 1.0% and 10.0% (v/v) O2 (optimum between 4.0% and 8.0% (v/v) O2).

Phylogeny Phylogenetic analysis based on 16S rDNA sequences indicate that strain CP.B2 belongs to the order Aquificales and represents the type strain of a novel species of a new genus within the family Hydrogenothermaceae. The 16S rRNA gene sequence for strain CP.B2 is deposited in the GenBank nucleotide sequence database under accession number DQ989208. The G+C content of the genomic DNA is 29.3 mol% which is the lowest G+C content reported for a species of the order Aquificales.

Tolerance to arsenic and antimony compounds Venenivibrio stagnispumantis displays tolerance to relatively high concentrations of arsenic and antimony compounds. Cells grew in the presence of up to 8 mM arsenite (As3+), 15 mM trivalent antimony (Sb3+), and >20 mM arsenate (As5+) but growth was not observed when As3+ and As5+ were provided as the sole electron donor and acceptor pair.

Nomenclature Ve.ne.ni.vi' bri.o. (Latin: the vibrio of poison) stag.ni.spu.man' tis. (Latin: from the bubbling pool, pertaining to Champagne Pool).

Culture collection Venenivibrio stagnispumantis strain CP.B2 is deposited in the Japan Collection of Microorganisms under JCM 14244, in the American Type Culture Collection under ATCC BAA-1398 and in the German Collection of Microorganisms under DSM 18763.

Culture medium

The pH of the medium is adjusted to 5.5, distributed into culture vessels and autoclaved under CO2. After the inoculation the initial gas phase is replaced with H2 / CO2 / O2 (79% / 15% / 6%) and pressurized to 170 kPa.

The pH of the solution is adjusted to 3.0 with HCl.

Worked examples

Example 1 — a first encounter with Venenivibrio stagnispumantis

Start with the simplest possible case. Write down what Venenivibrio stagnispumantis 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 Venenivibrio stagnispumantis 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 Venenivibrio stagnispumantis 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 Venenivibrio stagnispumantis

In research: Venenivibrio stagnispumantis 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 Venenivibrio stagnispumantis 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: Venenivibrio stagnispumantis is common in secondary-school and first-year university syllabi. It links to neighbouring topics Aquificota, Bacteria described in 2008, so understanding it makes those chapters shorter.
In everyday life: Look for Venenivibrio stagnispumantis 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.
