A type of anaerobic bacteria called nitrogen fixing bacteria.
bacterias
Ammonia, nitrates, nitrites
Amines + Nitrates/Nitrites = carcinogenic nitrosamines
zinc reduces nitrates to nitrites. The development of red color therefore verifies that nitrates were not reduced to nitrites by the organism. If the nitrates were not reduced, a negative nitrate reduction reaction has occurred
Ammonium; nitrates; nitrites
Humans and other animals usually have bacteria that convert nitrates into nitrates in their large intestines. For adults, the presence of these bacteria in the digestive system is not harmful, because the stomach of an adult is so acidic that the bacteria cannot survive. But the stomach of an infant is much less acidic, so the bacteria can move up into the stomach, where they will convert nitrates into nitrites. The nitrites can then pass into the blood of the infant.

According to WebMD: Nitrites. Bacteria that cause a urinary tract infection (UTI) make an enzyme that changes urinary nitrates to nitrites. Nitrites in urine show a UTI is present.
A nitrate is represented by -NO3 whereas a nitrite is represented by -NO2. So to answer your question, nitrates have 1 oxygen atom more than nitrites.
