Yamadazyma keroseneae

Yamadazyma keroseneae is a biology 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 Yamadazyma keroseneae rather than just read about it. In short: Yamadazyma keroseneae is a species of yeast in the genus Yamadazyma, family Saccharomycetaceae. Described as new to science in 2011, it was isolated from aviation fuel.

Key takeaways

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

Reference excerpt

Yamadazyma keroseneae is a species of yeast in the genus Yamadazyma, family Saccharomycetaceae. Described as new to science in 2011, it was isolated from aviation fuel.

Taxonomy The type strain of this yeast (IMI 395605T) was isolated from aircraft fuel (kerosene) sampled from a European aircraft. Later analysis demonstrated that the isolated strains were able to grow in liquid media containing 50% Jet A-1 aviation fuel. Molecular analysis was performed using the ribosomal RNA gene sequences of internal transcribed spacer regions in addition to the D1/D2 domains of the 26S nuclear ribosomal RNA gene. The two isolated strains clustered within the Candida membranifaciens clade, with C. tumulicola as the most closely related species. The specific epithet keroseneae is New Latin for kerosene, the substrate of the new species.

Description The yeast cells, after growth on glucose-peptone-yeast extract broth culture for three days at 25 °C (77 °F), are egg-shaped to elongated, measuring 3–11 by 1–3.5 μm. They occur singly, in budding pairs, or as short pseudohyphae. The yeast can assimilate the following carbon sources: glucose, galactose, sucrose, L-arabinose, cellobiose, maltose, trehalose, lactose, D-xylose, rhamnose, isomaltulose, melibiose, melezitose; mannitol, sorbitol, glycerol, erythritol; N-acetyl glucosamine, 2-ketogluconate, α-methyl-D-glucoside, levulinate and glucosamine. The yeast grew at a variety of temperatures between 25 and 37 °C (77 and 99 °F), but no growth was observed at 5 °C (41 °F) or 40 °C (104 °F). The kerosene from which the two yeast strains were isolated was analyzed with gas chromatography and shown to have 48 identifiable components. C. keroseneae appears to consume the n-alkane compounds hexadecane, heptadecane, and octadecane. Other microbes that can contaminate fuels include the yeast Yarrowia lipolytica, the filamentous fungus Hormoconis resinae, and the bacterium Pseudomonas aeruginosa.

Worked examples

Example 1 — a first encounter with Yamadazyma keroseneae

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

In research: Yamadazyma keroseneae appears in biology 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 Yamadazyma keroseneae 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: Yamadazyma keroseneae is common in secondary-school and first-year university syllabi. It links to neighbouring topics Fungi described in 2011, Fungus species, Pichiomycetes, so understanding it makes those chapters shorter.
In everyday life: Look for Yamadazyma keroseneae 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.
