A thermophile grows at high temperatures, an acidophile grows at low pH, an
osmophile grows at high solute concentration, and so on. Erwinia caratovora is
classed as an acidophile. Hence most of the "cures" treatments that we attempt
use with a modicum of success are basic/alkaline in nature and raise the pH.
