The breaking down of the humus and building of the nitrogen into other substances is the work of another set of bacteria or germs called nitrifying germs. ❋ Charles Landon Goodrich (N/A)
As regards the ammonium carbonate accumulating in the soil from the conversion of urea and other sources, we know from Winogradsky's researches that it undergoes oxidation in two stages owing to the activity of the so-called "nitrifying" bacteria (an unfortunate term inasmuch as ❋ Various (N/A)

It works by creating a large surface area for de-nitrifying bacteria to colonize out of the substrate itself, but may not be the best choice for saltwater aquariums. ❋ Unknown (2007)
However, the triple N-N bond makes N2 almost inert, and only a few microorganisms have the capability to utilize (fix) N2, converting it to the more easily utilizable combined nitrogen forms – initially ammonia (NH3), or its protonated species, ammonium (NH4+) that is terminally oxidized to nitrate (NO3 -) by nitrifying bacteria. ❋ Unknown (2006)
Because of the nitrifying bacteria in nodules on its roots, it is especially effective in improving the fertility of eroded soils. ❋ Unknown (1983)
In this manner he studied the metabolism of sea-urchin eggs, blood corpuscles, and various bacteria and especially the respiratory processes of nitrifying bacteria. ❋ Unknown (1965)
Among these phosphoric acid is one of the most important, and in the experiments on nitrification it has been found that the nitrifying organisms will not develop in any medium destitute of it. ❋ Charles Morton Aikman (N/A)
Warington at Rothamsted, who showed that the power of nitrification could be communicated to media, which did not nitrify, by simply seeding them with a nitrifying substance, and that light was unfavourable to the process. ❋ Charles Morton Aikman (N/A)
To this class of organism the nitrifying organisms belong. ❋ Charles Morton Aikman (N/A)

When, however, a small portion of a nitrifying soil was added, the power was regained. ❋ Charles Morton Aikman (N/A)
Finding that under these conditions the nitrifying organism increased enormously and displayed its full vigour, he proceeded further to determine the amount of carbonaceous organic matter formed in solutions after the introduction of the organism. ❋ Charles Morton Aikman (N/A)
Organic matter, in bones, 363; in dung, 228, 260; in manures, 543; not necessary for nitrifying organism, 169. ❋ Charles Morton Aikman (N/A)
The gypsum neutralises the alkalinity of nitrifying solutions by converting the alkaline ammonium carbonate into neutral ammonium sulphate, the calcium carbonate being precipitated. ❋ Charles Morton Aikman (N/A)
The nitrifying organisms are also found in river-water, in sewage, and well-waters. ❋ Charles Morton Aikman (N/A)
The reason of its favourable action is probably because it neutralises the alkalinity of nitrifying solutions. ❋ Charles Morton Aikman (N/A)
These forms are universally present in nitrifying cultures. ❋ Charles Morton Aikman (N/A)
The nitrifying organisms are probably chiefly confined to the soil, and do not usually occur in rain or in the atmosphere. ❋ Charles Morton Aikman (N/A)
The absence of the nitrifying organisms in certain soils, such as peaty and forest soils, may be thus accounted for. ❋ Charles Morton Aikman (N/A)
