NC10 phylum

NC10 phylum 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 NC10 phylum rather than just read about it. In short: NC10 is a bacterial phylum with candidate status, meaning its members remain uncultured to date. The difficulty in producing lab cultures may be linked to low growth rates and other limiting growth factors.

Key takeaways

NC10 phylum belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect NC10 phylum to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NC10 phylum from memory before moving on to harder problems.

Reference excerpt

NC10 is a bacterial phylum with candidate status, meaning its members remain uncultured to date. The difficulty in producing lab cultures may be linked to low growth rates and other limiting growth factors. Methylomirabilis oxyfera, a member of the NC10 phylum, is the first organism discovered to couple methane oxidation to the reduction of nitrite to dinitrogen (N2). This is significant for several reasons. First, there are only three other biological pathways known to produce oxygen (photosynthesis, chlorate respiration, and the detoxification of reactive oxygen species). Second, anaerobic methane oxidation (AMO) coupled to nitrite reduction links the global carbon and nitrogen cycles, and thus denitrifying methanotrophs in the NC10 phylum may influence methane content in the atmosphere. Third, this finding opens the possibility that oxygen was available in the atmosphere prior to the evolution of oxygenic photosynthesis and the Great Oxidation Event, which challenges certain aspects of modern theories regarding the evolution of early life on Earth. The NC10 phylum was first proposed in 2003 on the basis of highly divergent 16S rRNA gene sequences from aquatic microbial formations in flooded caves (Nullarbor caves, Australia). The first genome insights for the phylum were published in 2010. Members of the NC10 phylum have been detected in environments including the Brunssummerheide peatlands (Limburg, Netherlands), the deep stratified Lake Zug (Central Switzerland), and a paddy field with long-term fertilization (Hangzhou, China) NC10 species proposed to date include Methylomirabilis oxyfera and Methylomirabilis lanthanidiphila

Taxonomy

The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) and National Center for Biotechnology Information (NCBI). However many taxonomic names are taken from the Genome Taxonomy Database release 06-RS202.

Worked examples

Example 1 — a first encounter with NC10 phylum

Start with the simplest possible case. Write down what NC10 phylum 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 NC10 phylum 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 NC10 phylum 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 NC10 phylum

In research: NC10 phylum 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 NC10 phylum 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: NC10 phylum is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bacteria phyla, Candidatus taxa, so understanding it makes those chapters shorter.
In everyday life: Look for NC10 phylum 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.
