✦ Synopsis

The rate of NADH formation decreases significantly over a period of 20 h. The coupling of a reaction rapidly consuming NADH (Scheme 1) increases the rate and stabilizes the reaction, even over a longer period of time. The coupled reaction was the reduction of pyruvate to L-lactate (catalyzed by L-LDH). The lactate formation at the electrode of type (i) was 148 nmol cm-' in 20 h compared to 13.5 nmol cm-2 NADH in 19.5 h with a comparableelectrode without coupling of an NADH-consuming reaction. In control experiments it was established that all the lactate originates
