在本研究中，诺卡氏菌属和红球菌属被清楚地区分。十一个特征被证明有助于区分这两个属。 Tsukamura 先前定义的小行星诺卡氏菌分为两个分类群。其中一个包含模式菌株，并被认为以新的意义保留了小行星诺卡氏菌的名称。另一种在本研究中被命名为诺卡氏菌（Nocardia nova sp）。十一月冢村。该物种的模式菌株是ATCC 33726。以下七个特征可用于区分新星新星和新定义的小行星新星：1）14天后芳基硫酸酯酶活性； 2) 过氧化氢酶活性（半定量）； 3）β-酯酶活性； 4)吡嗪酰胺酶活性； 5)利用柠檬酸盐作为唯一的碳源； 6)利用2,3-丁二醇作为唯一碳源； 7) 对 5-氟尿嘧啶 (20 μg/ml) 的耐药性。
The genera Nocardia and Rhodococcus were clearly differentiated in the present study. Eleven characteristics were shown to be useful for differentiation between these two genera. Nocardia asteroides sunsu stricto previously defined by Tsukamura was divided into two taxa. One contained the type strain and was considered to retain the name Nocardia asteroides in a new sense. Another was named in the present study as Nocardia nova sp. nov. Tsukamura. The type strain of this species is ATCC 33726. The following seven characters were useful for differentiating N. nova from newly defined N. asteroides: 1) arylsulfatase activity after 14 days; 2) catalase activity (semiquantitative); 3) β‐esterase activity; 4) pyrazinamidase activity; 5) utilization of citrate as a sole source of carbon; 6) utilization of 2,3‐butylene glycol as a sole carbon source; and 7) resistance to 5‐fluorouracil (20 μg/ml).
