Power requirement in fermentors with and without aeration was studies in relation to design and/or operation variables. Some different relationship from that published previously was found. Modifications of the original equations were made to imterpret this discrepancy as follows : (1) The ralation given by Oyama and Endoh was modified by classifying the data obtained, using the ratios of liquid depth to the upper impeller, H_a, to impeller diameter, D_i. When the ratio was almost 1 : 1,the equation was P_g/P_0=1.02N^'_Δ-1/(12.5) N^'_A=(Q/N・D^2_i・W_i)・10^2 Where, P_g/P_0 were obtained to have the values of 0.7-1.0 which were larger than those by Oyama and Endoh. (2) The equation of Michel and Miller was modified in its term of the aeration rate, Q, as P_g=2.4(P^2_0・N・D^3_i/Q<0.08>)^<0.39>・10-<-3> On the other hand, the relations of P_g/P_0 by Nagata et al., P_0 by Rushton et al. and P_0 by Nagata et al. to these variables were also examined. There were few regularities that could be well formulized.
