Thermodesulfobacterium hveragerdense 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 Thermodesulfobacterium hveragerdense rather than just read about it. In short: Thermodesulfobacterium hveragerdense is a bacterial species belonging to genus Thermodesulfobacterium, which are thermophilic sulfate-reducing bacteria. This species is found in aquatic areas of high temperature, and lives in freshwater like most, but not all Thermodesulfobacterium species It was first isolated from hotsprings in Iceland.

Key takeaways

Thermodesulfobacterium hveragerdense belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Thermodesulfobacterium hveragerdense to a quantity you can measure, compute or draw — that is where exam questions come from.

Reference excerpt

Thermodesulfobacterium hveragerdense is a bacterial species belonging to genus Thermodesulfobacterium, which are thermophilic sulfate-reducing bacteria. This species is found in aquatic areas of high temperature, and lives in freshwater like most, but not all Thermodesulfobacterium species It was first isolated from hotsprings in Iceland.

Habitat Thermodesulfobacterium hveragerdense is a thermophile, which means that it thrives at high temperatures. It is found in aquatic niches where the temperature is very high and where there is an abundance of sulfur deposits. Thus, they are found in or near volcanic hot springs that are slightly acidic. Thermodesulfobacterium hveragerdense is capable of growing in temperatures that range from 55 °C to 74 °C (131 °F to 166 °C), but their optimal growth temperature is 70-74 °C. Thermodesulfobacterium hveragerdense thrives in slightly acidic pH levels, with the optimal pH for growth being 6.5-7.0.

Cell morphology Thermodesulfobacterium hveragerdense inhabits bacterial mats and, hence, it lacks a flagellum for mobility. The cell is cylindrical, its dimensions being 2.5μm × 0.5μm. This roughly equates to a cell body volume of 1.96 μm3. The cells form chains of up to three cells long, rarely exceeding this number.

Cell membrane Thermodesulfobacterium hveragerdense has a phospholipid bilayer membrane. The lipids of the membrane are mainly dietherglycerophospholipids(DEG-P), but there are also many diacylglycerophospholipids(DAG-P) and acyl/etherglycerophospholipids(AEG-P) in the lipid bilayer as well. The bilayer also contains minute amounts of diphosphatidylglycerol (DPG) compounds in it, mainly phosphatidylethanolamine, phosphatidylinositol, and aminopentanetetral.

Metabolism Thermodesulfobacterium hveragerdense is not an anaerobic organotrophic organism, which means that it relies on organic substances for nutrition and it does not require oxygen. Thermodesulfobacterium hveragerdense is a sulfur-reducing bacteria. It utilizes sulfate (SO4−2) as electron acceptors, and thiosulfate and sulfite as electron donors. The reducing of sulfur and the elimination the oxygen, yields hydrogen sulfide(H2S). Hydrogen sulfide is responsible for what is referred to as rotten egg smell.

Genome The genome of Thermodesulfobacterium hveragerdense, has been sequenced via whole genome shotgun sequencing. The genome consists of 1.7 million base pairs(Mbp), and contained a total of 1,810 genes. Specific information about the genome is listed below: Genome Size: 1,726,173 base pairs Total Genes: 1,810 genes Coding Genes: 1,696 genes Coding Sequences: 1,758 sequences Protein Coding Sequences: 1,696 sequences RNA Genes: 52 RNA genes rRNAs: 1 5s rRNA, 1 16s rRNA, 1 23S rRNA

5s rRNA: This rRNA is important for ribosomal structure stabilization during protein synthesis, which actually enhances protein synthesis. This also helps determine the phylogenetic trees of many organisms 16s rRNA: This rRNA is used for phylogenetic purposes, because the function of this gene has not changed over time, it is present in most bacteria, and the sequence is large enough to informatic purposes as well. 23s rRNA: This rRNA is very important in the process of binding tRNA to ribosomal functional sites. tRNAs: 46 tRNAs ncRNAs: 3 ncRNAs Pseudogenes: 62 pseudo genes

Worked examples

Example 1 — a first encounter with Thermodesulfobacterium hveragerdense

Start with the simplest possible case. Write down what Thermodesulfobacterium hveragerdense 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 Thermodesulfobacterium hveragerdense 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 Thermodesulfobacterium hveragerdense 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 Thermodesulfobacterium hveragerdense

In research: Thermodesulfobacterium hveragerdense 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 Thermodesulfobacterium hveragerdense 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: Thermodesulfobacterium hveragerdense is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bacteria described in 2000, Thermodesulfobacteriota, so understanding it makes those chapters shorter.
In everyday life: Look for Thermodesulfobacterium hveragerdense 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.
