ECM associations enable host plants to survive in soils characterized by impoverished nutrient status, e.g. acidic, nitrogen and phosphorus deficient soils (Read 1996).
In the histidine proton shuttle, histidine abstracts a proton with its basic nitrogen to make a positively-charged intermediate, and then use another molecule, a buffer, to extract the proton from its acidic nitrogen.
For example, Gasch et al. (2000) and Causton et al. (2001) used genome-wide expression analysis to explore how gene expression in yeast is remodeled over time as cells respond to heat shock, oxidative shock, osmotic shock, acidic stress, nitrogen depletion, amino acid starvation, etc.
First, genome-wide gene expression time profiles under various stress conditions such as heat shock, oxidative shock, osmotic shock, acidic stress, nitrogen depletion, and amino acid starvation are from Gasch et al. (2000) and Causton et al. (2001).
We applied STFIA to find the stress TFs that are involved in responding to heat shock, oxidative shock, osmotic shock, acidic stress, nitrogen depletion, and amino acid starvation, respectively.
In the smokestack, different filters remove oxides of sulphur and nitrogen, acidic gases, heavy metals and soot.
The suit also raised alarm about Greek yogurt's chief by-product, whey an acidic mixture, containing nitrogen and phosphorous, that is commonly disposed of by being added to cattle feed and fertilizer or treated in a digester, which breaks down the whey, producing methane gas that can be harnessed for energy.

It was designed to monitor the chemical and biological response of acidified surface waters in the UK to the planned reduction in the emission of acidic sulphur and nitrogen gases as required by the UNECE Convention on Long Range Transboundary Air Pollution.
Additionally, a distinct picture of the base-acid transition is evaluated using in situ FTIR-ATR measurements in electrolytes containing the supporting salts KPF6HPF6, NaClO4HClO4 and NaReO4HReO4 The results demonstrate that in strong acidic media leucoemeraldine nitrogen atoms can be partly protonated.
Talaron is water-soluble acidic polysaccharide containing nitrogen and phosphorus, and its molecular weight was estimated to be 7000 8000.
