Then anaerobic bacteria take that nitrate and turn it into harmless nitrogen gas.
It is one of nature's great ironies that the availability of nitrogen in the soil frequently sets an upper limit on plant growth even though the plants' leaves are bathed in a sea of nitrogen gas.
Aiming to extend the shelf life of peanut protein powder, the effect of adding antioxidants and antioxidant synergists, coupled with nitrogen gas packing, were studied in this work.
Introduced the structure and characteristics of nitrogen gas spring, listing several kinds of application in auto die, and finally points out its way in application note.
Then it gets rather more high-tech. Capua's high-vacuum, low-temperature equipment removes bergaptene, an irritant, from the oil; and it is then stored under nitrogen gas to stop it oxidising.
