In these areas, nitrate(NO3-) or nitrite(NO 2-) can be used as a substitute terminal electron acceptor instead of oxygen(O2), a more energetically favourable electron acceptor.
Once some stimulative drugs wear off, a common side effect is a period of depression or anxiety, colloquially called a"come down";amyl nitrite is sometimes used to combat these negative after-effects.
Members of the genus Nitrobacter oxidize nitrite as a source of energy and reductant, and use CO2 as a carbon source.[11] Nitrite is not a particularly favourable substrate from which to gain energy.
Once some stimulative drugs wear off, a common side effect is a period of depression or anxiety, colloquially called a"come down";amyl nitrite is sometimes used to combat these negative after-effects.
Such carcinogenic nitrosaminescan also be formed from the reaction of nitrite with secondary amines under acidic conditions(such as occurs in the human stomach) as well as during the curing process used to preserve meats.
