• The relationship between ethanol consumption and the bioreduction of prochiral ketones in bakers' yeast cells using ethanol as a reductant for NAD(P)H regeneration was examined and the efficiency (ν_<sub>/ν_<EtOH>) correlated to k_Lα. Ethanol was consumed at almost the same specific rate in the presence or absence of the ketones.In the reduction of ethyl acetoacetate catalyzed by NADPH-dependent oxidoreductase, the efficiency (ν_<EA>/ν_<EtOH>) decrased with increasing k_Lα as about 0.5 at the actual operating conditino of k_Lα of 100 h^<-1>. The reduction of acetol catalyzed by NADH-dependent oxidoreductase proceeded through the use of a porition of NADH in the regenerated NADH, and the efficiency (ν_<acetol>/ν_<EtOH>) had a maximum (1.9) at k_Lα of 20 h^<-1>.
