utilization of h ( 2 ) o ( 2 ) by the peroxidase was favored by ( i ) increasing either the peroxidase or the i ( - ) concentration , so as to increase the rate of oxidation of i ( - ) , ( ii ) lowering the temperature to lower the rate of destruction of h ( 2 ) o ( 2 ) by the bacteria , and ( iii ) adding h ( 2 ) o ( 2 ) in small increments so as to avoid a large excess of h ( 2 ) o ( 2 ) relative to i ( - ) .
