Why does a low pH prevent the growth of certain micro-organisms?
The growth and survival of micro-organisms, that is, the various meabolic
functions, frequently depend upon the acidity of growth environment. The
pH = - log(H+) = log1/(H+) measures the acidity. Often the survival of the
micro-organism is very sensitive to that parameter. Various functions are
retarded (or accelerated) by a change in pH.
