Oxygen absorption in bubble aeration was studied with the gluconic acid fermentation using a strain of Pseudomonas ovalis. The oxygen transfer coefficients (k_L and k_m) of liquid films which were assumed to exist around air bubbles and resting cells respectively, were estimated.It was difficult to recognize a substantial difference between the values of k_L and k_m because of the fact that the film coefficient k_m of the cells ranged from about 10^<-1> to 10^<-13> cm/sec, while the value of k_L was of the order of 10^<-2> cm/sec which pertaints to air bubbles several millimeters in diameter.It was also found that the value of k_m referred to above was large compared with that of k_m' which is related to the cells without aeration. The ratio k_m'/k_m extended from 0.53 to 0.85,the numerical values of which were not affected appreciably when the aeration ranged from 0.5 to 5.0 v.v.m.
