To investigate the behavior of surface grown acetic acid bacteria toward oxygen, a special vessel was devised for measurement of surface respiration. Using a strain belonging to the fermentation type experiments were conducted on A) surface respiration of surface grown cells, B) submerged respiration of surface grown cells, and C) submerged respiration of submergedly grown cells. In all cases, respiratory activity vs. oxygen tension plots showed Michaelis' relationship. The oxygen terminal factor in A plays the role of rate-limiting factor for uptake of atmospheric oxygen, but it indicated very low affinity toward oxygen (K_m=0.23 atm). In the case of B and C, the specific respiration rate decreased to less than falf of that in A, however the affinities to oxygen (K_m=0.021 and 0.013 atm) were considerably lower than that of cytochrome. But the cytochrome system was shown by an inhibition test to play an important role, too. From the results, a great difference was indicated between the behavior toward oxygen of the strain employed and the behavior of a submerged fermentation type strain having a high affinity to dissolved oxygen, in the view of the low affinity to oxygen of the respiratory rate-limiting factor.
