Nitrifiers are fragile microorganisms which are sensitive to ,acid, despite the fact that they produce ,acid, during oxidation of ,ammonia, and nitrite. If a large source of ,nitrogen, is dumped into the environment, these organisms can potentially kill themselves by metabolizing it to nitric ,acid,, unless pH is buffered with limestone or other slow-dissolving sources of alkalinity..
