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.
研究了微杆菌科四个不同属代表菌株中末端氧化酶的性质。发现植物杆菌属和奥基杆菌属所有被研究菌株的对数后期和稳定前期细胞含有aa3型细胞色素氧化酶。 Rathayibacter属和Agreia属细菌合成三种氧化酶，即bb3型和aa3型细胞色素氧化酶以及非血红素抗氰氧化酶，其比例取决于培养条件和生长阶段。培养基中的缺氧诱导所有被研究微生物中bd型氧化酶的合成。所获得的数据表明，末端氧化酶的类型与已知的化学分类特征一起，可在表型水平上用于区分微杆菌科的属。
