Methylacidiphilum fumariolicum

Methylacidiphilum fumariolicum is a chemistry 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 Methylacidiphilum fumariolicum rather than just read about it. In short: Methylacidiphilum fumariolicum is an autotrophic bacterium first described in 2007 growing on volcanic pools near Naples, Italy. It grows in mud at temperatures between 50 °C and 60 °C and an acidic pH of 2–5.

Key takeaways

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

Reference excerpt

Methylacidiphilum fumariolicum is an autotrophic bacterium first described in 2007 growing on volcanic pools near Naples, Italy. It grows in mud at temperatures between 50 °C and 60 °C and an acidic pH of 2–5. It is able to oxidize methane gas. It uses ammonium, nitrate or atmospheric nitrogen as a nitrogen source and fixes carbon dioxide. Due to the presence of a lanthanide dependent methanol dehydrogenase enzyme, its growth is strictly dependent on the abundance of rare-earth metals. No biotic interactions between M. fumariolicum and other organisms are known, probably due to the extreme environment the bacteria needs in order to grow.

Biology

Genome The genome of M. fumariolicum is 2.36 Mbp in size with a GC-content of 40.9% and 2,283 protein encoding genes.

Metabolism Energy is obtained by methane oxidation to methanol and by the enzyme methanol dehydrogenase which is strictly dependent on the use of rare-earth metals as cofactors. It generally uses lanthanum as an essential cofactor but it has been shown that it can be replaced with other lanthanides such as cerium, praseodymium, or neodymium without negative effects and with samarium, europium, or gadolinium only slowing down the growth speed of the bacteria. It uses the Calvin Benson Bassham cycle to fixate carbon dioxide and use it as a carbon source. In fact concentrations of CO2 below 0.3% (v/v) impairs any growth of M. fumariolicum. M. fumariolicum was found to be more oxygen sensitive than most Pseudomonadota methanotrophs, probably due to the fact that it uses nitrogenase during nitrogen fixation which is known to be oxygen sensitive.

Worked examples

Example 1 — a first encounter with Methylacidiphilum fumariolicum

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

In research: Methylacidiphilum fumariolicum appears in chemistry 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 Methylacidiphilum fumariolicum 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: Methylacidiphilum fumariolicum is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bacteria described in 2007, Candidatus taxa, Verrucomicrobiota, so understanding it makes those chapters shorter.
In everyday life: Look for Methylacidiphilum fumariolicum 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.
