Abstract:
The nature of terminal oxidases in representatives of four different genera of the family Microbacteriaceae was studied. It was found that the late-logarithmic and early-stationary cells of all of the investigated strains of the genera Plantibacter and Okibacterium contain the aa3-type cytochrome oxidase. Bacteria of the genera Rathayibacter and Agreia synthesize three oxidases, the bb3- and aa3-type cytochrome oxidases and nonheme cyanide-resistant oxidase, in proportions dependent on the cultivation conditions and the growth phase. Oxygen deficiency in the cultivation medium induces the synthesis of the bd-type oxidase in all of the microorganisms studied. The data obtained provide evidence that the type of terminal oxidases, along with the known chemotaxonomic characteristics, may serve to differentiate the genera of the family Microbacteriaceae at the phenotypic level.
