Wickerhamomyces

Wickerhamomyces 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 Wickerhamomyces rather than just read about it. In short: Wickerhamomyces is a genus of fungi within the Phaffomycetales order. It is placed within the family of Phaffomycetaceae.

Key takeaways

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

Reference excerpt

Wickerhamomyces is a genus of fungi within the Phaffomycetales order. It is placed within the family of Phaffomycetaceae.

Description The fungi has asexual reproduction and that budding is multilateral on a narrow base. The cells are spherical, ovoid, or elongate in shape. Pseudohyphae and true hyphae (a long, branching, filamentous structure) are produced by some species. In sexual reproduction, it is found that the asci (spore bearing cell) may be unconjugated or show conjugation between a cell and its bud or between independent cells. Some species are heterothallic (species have sexes that reside in different individuals). Asci may be persistent or deliquescent and form one to four ascospores that may be hat-shaped or spherical with an equatorial ledge.

Taxonomy The genus name of Wickerhamomyces is in honour of Lynferd J. Wickerham (1910-1990), who was an American botanist and taxonomist, who worked at the National Center for Agricultural Utilization Research. In 1970, Wickerham had authored 'Genus 14. Pachysolen Boidin et Adzet, pp. 448–454. In J. Lodder (ed.), The Yeasts. A taxonomic study, 2nd ed. North-Holland Publishing Co., Amsterdam.' The genus was circumscribed by Cletus P. Kurtzman, Christie J. Robnett and Eleanor Basehoar-Powers in FEMS Yeast Res. vol.8 (Issue 6) on page 951 in 2008.

Species As accepted by GBIF;

Some genera have been re-assigned from Pichia family; such as W. canadensis, W. ciferri, W. lynferdii, W. salvicola and W. subpelliculosa. Wickerhamomyces is very divergent, and the three basal species; W. hampshirensis, W. pijperi and W. strasburgensis may be shown by future studies to be members of a sister genus.

Uses Yeasts belonging to the genera Candida, Pichia, and Wickerhamomyces have been found in Aedes and Anopheles genera of mosquitoes. Wickerhamomyces anomalus has also been isolated from the gonads of mosquitoes. It can then be used as a Glucanase to control the spread of plasmodium infection in malaria mosquitoes. Wickerhamomyces anomalus has also been found in budbod (a Philippine rice cake, also known as marcha in India) and found in various other Asian countries. Such as Nepal and Tibet, where these alcoholic beverages (called Chhaang) are generated using a traditional starter called murcha. Murcha is prepared by using yeast and mold flora of wild herbs in cereal flours. It has also been used as a biocontrol agent to prevent fungal contamination of grains and produce. Wickerhamomyces anomalus yeast is also used during the early stages of alcoholic fermentation, adding significantly to the character and quality of the wine. It helps in the sensory aroma of lily rice wine. Wickerhamomyces silvicola has been found in the gum of the wild black cherry tree (Prunus serotina) and W. subpelliculosus in cucumber brine. Wickerhamomyces strasburgensis is found as slime flux on the Douglas fir. W. sylviae have been found in yeasts isolated from inside migratory birds, although it is unclear if the bird ate an insect that (then) contained the fungus. The yeast is used in the fermentation of decoction of Saraca asoca bark to develop a suitable method for preparing its polyherbal formulation, of Asokarista. This is an Ayurvedic herbal medicine used to treat ‘female disorders’ or for menstrual disorder and female hormonal imbalances.

Worked examples

Example 1 — a first encounter with Wickerhamomyces

Start with the simplest possible case. Write down what Wickerhamomyces 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 Wickerhamomyces 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 Wickerhamomyces 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 Wickerhamomyces

In research: Wickerhamomyces 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 Wickerhamomyces 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: Wickerhamomyces is common in secondary-school and first-year university syllabi. It links to neighbouring topics Ascomycota genera, Saccharomycetes, Taxa described in 2008, so understanding it makes those chapters shorter.
In everyday life: Look for Wickerhamomyces 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.
