The Adsorption of H+ by Bacteria as Measured by the Glass Electrode

Abstract

When living bacteria were washed with distilled water and added to a soln. containing an acid highly ionized the pH value of the soln. became significantly higher, proving that the H+ conc. of the soln. was decreased. Calculations made from the change in H+ in a soln. containing a known wt. of bacterial cells showed that different bacteria were capable of adsorbing H+, varying from 38-70 m.e. (milli-gram equivalents) per 100 g. of bacteria dried at 105[degree]C.
