The scale-up method of fermentors was studies based on volumetric oxygen transfer coefficients, and the relationship between the coefficients and the design and/or operation variables was found somewhat different from that in published previously. In order to interpret this discrepancy, the conventional equations were modified : (1) Richards' equation was modified by adding a corrected term of impeller-stage number, N_i, as k_d=(2.0+2.8N_i)・(P_g/V)^<0.56>V^<0.7>_5N^<0.7>・10^<-3> (2) Humphrey's equation was modified in its term of impeller diameter, D_i. as k_d=0.63N^<4'3>・D^<0.24>i・V^<1/2>_5・10^< : -3>-2.0 Using these equations, a uniform and acceptable relationship was found over a wide range of these variables. On the other hand, the equations of Cooper et al. and Sato and Miyamoto were also examined. There were few regularities to be well formulized.
