Most of these studies have confined that the main terminal oxidase system in microorganisms is cytochrome-cytochrome oxidase system as well as in mammalian tissues. Other terminal oxidase systems such as DPNH oxidase-peroxidase system (1) have also been reported, and many speculations have been done concerning the existence of the terminal oxidase system which does not possess cytochrome or cytochrome oxidase. However, it is quite unknown whether or not these terminal oxidase systems are coupled with the energy generating system such as the oxidative phosphorylation system, and the physiological significance of these systems is quite obscure. On the other hand, as it is well known, microorganisms have an ability to exhibit characteristic biochemical phenomena concerning the adaptability to exhibit characteristic biochemical phenomena concerning the adptability to an environment, especially to produce an adaptive enzyme, which is quite unexpectable in animal and higher plant.  aCianeto  aBacterias  aEnzimas  aMicroorganismo1 aNAKANO, M.1 aSAKAGUCHI, K.  tThe Journal of Biochemistrygv.46, n.3, p.373-381, 1959.
