Talk:Nitrifying bacteria

Nitrosifyers

Although there is a few (3 or so) articles that use the term "Nitrosifyers" to describes ammonia oxidizing microbes (bacteria), this term is not used in scientific jargon anymore, where ammonia oxidizing and nitrite oxidizing bacteria are jointly referred to as "nitrifiers". uuuǝıɹ 15:01, 13 February 2013 (UTC) — Preceding unsigned comment added by Riennn (talk • contribs)

Sources of oxygen

Are we sure that the oxygen atom in the NO2 -> NO3 step comes from O2? The Nitrification pages lists otherwise. 216.59.231.35 16:41, 10 November 2006 (UTC)

The 2nd stochiometric equation for the nitrosifying reaction is wrong. obviously there are only 2 oxygens on the left but three on the right side... lol. my bio teacher also did this wrong...--84.74.162.3 (talk) 09:06, 25 January 2009 (UTC)

stochiometric equations are wrong anyway here because they lack the intermediary steps. uuuǝıɹ 14:59, 13 February 2013 (UTC)

The conversion of NO2 -> NO3 (almost always) requires an oxidizing environment with DO > 1.5 or so...it would be unlikely that any significant oxygen could come from other sources. Good question though. 67.175.156.8 (talk) 18:02, 17 February 2014 (UTC) John W. Norton, Jr., PhD. PE

Confusing wording

Nitrifying bacteria are chemoautotrophic or chemolithotrophs depending on the genera

Classifying nitrifying bacteria as chemoautotrophic or chemolithotrophs is confusing. All nitrifying bacteria are by definition chemotrophs, since they are not phototrophs, and they are all lithotrophs as well, since they obtain energy for establishing a proton gradient from the oxidation of inorganic compounds (namely ammonia or nitrite). Regarding the auto- or heterotrophic growth, it appears that there can be both (for heterotrophic nitrifying bacteria see this link). I therefore think that a non-ambiguous wording would be: Nitrifying bacteria are chemolithotrophic organisms that can grow auto or hetero-trophically depending on the species. — Preceding unsigned comment added by Januoaxe (talk • contribs) 19:32, 4 September 2016 (UTC)

nothing about the origin of these bacteria ...

I believe I read a paper some 20 years ago about how these bacteria needed multi-cellular animal life to have evolved. Any sources? It would be a very important addition to the article. 104.169.16.163 (talk) 19:42, 29 August 2019 (UTC)

Missing genera

Some genera are missing from the tables of nitrifying bacteria. Namely Nitrosolobus from the AOB and Nitrotoga & Nitromaritima from the NOB — Preceding unsigned comment added by 89.205.225.170 (talk) 11:42, 14 May 2020 (UTC)
