[A: You must have slight acidity and low oxygen to ferment (grow) bacteria. Acidity and Low Oxygen go hand in hand, where you see one, the other will also exist. The OH- that gives alkalinity in body fluids has an excess of Oxygen compared to the H+ ion, that is difficient in Oxygen and an Electron. An electron is a region of energy.
