对营养琼脂平板上作为污染物出现的橙色革兰氏阴性球菌进行表型、化学分类学和 16S rDNA 序列分析，确定了副球菌属的一个新种。该菌株的表型特征与之前描述的所有或大多数副球菌属物种不同，包括其明亮的橙色，这是由大量类胡萝卜素（主要是虾青素）的合成引起的，以及它无法在呼吸中使用硝酸盐作为电子受体。建议将此生物体命名为Paracaccus marcusii。模式菌株是DSM 11574(T)。
Phenotypic, chemotaxonomic and 16S rDNA sequence analysis of an orange Gram-negative coccus that appeared as a contaminant on a nutrient agar plate delineated a new species of the genus Paracoccus. Phenotypic features of the strain that differ from all or most of the previously described Paracoccus species include its bright orange colour, caused by the synthesis of large amounts of carotenoids (mainly astaxanthin), and its inability to use nitrate as an electron acceptor in respiration. The name Paracoccus marcusii is proposed for this organism. The type strain is DSM 11574(T).
