The nitrate-nitrite-NO pathway is emerging as an important ... that may be specific for different tissues and/or at different pH or oxygen gradients. Moreover, it is important to understand ...

Nitrates "dissolve" in water and ... The soil conditions most favorable to this conversion process (called nitrification) include: a soil pH of 7, moisture at 50% of the soil's water-holding capacity, ...

2. The reduction was most active in solutions having a PH value of approximately 7.6. 3. The expressed juice of nitrogen-high tomato plants (containing both nitrates and sugar in abundance), after ...

In humans, dietary nitrate (mostly from green leafy vegetables) is converted to nitrite in saliva, and to nitric oxide (NO) in the acidic stomach. Petersson and colleagues hypothesized that ...

This is a differential medium. It is used to determine if an organism is capable of reducing nitrate (NO 3-) to nitrite (NO 2-) or other nitrogenous compounds via the action of the enzyme nitratase ...
