Abstract
Glucose and gluconic acid oxidases of three types of oxidative bacteria were studied by Zunberg method. (1) A. suboxydans, which oxidizes glucose to gluconic acid and gluconic acid to 5-ketogluconic acid, has powerfull glucose oxidase, and the gluconic acid oxidase appeares later. (2) Ps. gluconicum, which oxidizes glucose to gluconic acid, has glucose oxidase but not so active as A. suboxidans. The gluconic acid oxidase is absent. (3) Ps. f luorescens, which oxidizes glucoses to gluconic acid and glucnoic acid to 2-ketogluconic acid, has powerfull gluconic acid oxidase, but the glucose oxidase is very poor. (4) Glucose and gluconic acid oxidase of S. marcescens, which oxidizes glucose to 2-ketoglu-conic acid by submerged culture, are not detectable. Author thinks that oxidases of this bacteria ate not so constitutive as others.
