Intro, 2nd paragraph: I would cancel the sentence about endospores, in the 3rd paragraph it is clearly stated that no endospore-forming A. are known.

Comparison with other domains, table: genome (not gene) structure would be the better title of this line; in the RNA polymerase line, eukaryote column: "several" would be better (I, II, III and mitochondrial are not many, I guess). 2nd paragraph below this table: development of nucleus occurred even after split between A. and eukaryotes!

Relation to eukaryotes, 1st paragraph: what is the similarity in cell structure?? structurally A. are more similar to bacteria, as is pointed out earlier.

Metabolism, 1st paragraph: emphasis on inorganic compounds should be called lithotroph or chemolithotroph, not just chemotroph; 2nd paragraph: oxygen-generating or non-oxygen-generating (as in purple or green bacteria) photosynthesis does not occur....

Metabolism, last paragraph: strictly, retinal, not retinol, is the cofactor.

Significance in technology, 1st paragraph: classical PCR works with Taq polymerase from bacterial (not archaean) strain Thermus aquaticus! Pfu was only applied in PCR later, so PCR does not rely on it!

communication: what is a protein indel (LuxR indel)?? "Ligans" should be ligands. Wolfgang WolfGreg9 (talk) 20:34, 15 July 2024 (UTC)[reply]

cf "Significance in technology and industry" + medicine & health, essential aminoacids

1. Archaea are known for assembling the essential aminoacids and vitamines such as in the vitamine B family: it is even written in the articles on Vit B9 (=folate) and Vit B12:

Vit B9 : " All plants and fungi and certain protozoa, bacteria, and archaea can synthesize folate de novo through variations on the same biosynthetic pathway."
Vit B12: "Vitamin B12 is produced in nature by certain bacteria, and archaea.[69][70][71]".

I will add it to the article with the references. Have to go now. SvenAERTS (talk) 13:06, 19 August 2024 (UTC)[reply]

How to remove a redirect (if I should)?

Parvarchaeum acidophilus is a redirect to Archaea (this page). I do not understand why this is the case, and do not think it should be. I understand that the page for this species does not exist yet (I'll probably make one soon), but that doesn't mean its name should be a redirect to something else. Haplodiploid75 (talk) 13:46, 5 December 2024 (UTC)[reply]

I moved it to the LPSN-preferred name Parvarchaeum acidiphilum^[1] and changed the redirect to Parvarchaeota: "Candidatus Parvarchaeum acidiphilum" is the type species of Parvarchaeota. --Petr Karel (talk) 14:32, 5 December 2024 (UTC)[reply]
