The bacterium Gordonia sp. SCSIO19801, which could effectively utilize phenanthrene as the sole carbon source, was isolated from the seawater of the South China Sea. Its biodegradation characteristics, whole genome sequence, and biodegradation pathway were investigated. The phenanthrene biodegradation process of Gordonia sp. SCSIO19801 was estimated to be a first-order kinetic model with a k value of 0.26/day. Based on the identification of metabolites, utilization of probable intermediates, and genomics analysis of related genes, the degradation of phenanthrene by Gordonia sp. SCSIO19801 was proposed to occur via the salicylate metabolic pathway. This is the first report of a phenanthrene degradation pathway in Gordonia species. In addition, the Gordonia sp. SCSIO19801 could use other aromatic compounds as the sole source of carbon and energy. These characteristics indicate that Gordonia sp. SCSIO19801 can be utilized for developing effective methods for the biodegradation of petroleum hydrocarbons in marine environments.

细菌Gordonia sp. SCSIO19801 能够有效利用菲作为唯一碳源，是从南海海水中分离出来的。对其生物降解特性、全基因组序列和生物降解途径进行了研究。Gordonia sp.的菲生物降解过程。SCSIO19801 估计为一阶动力学模型，k值为 0.26/天。基于代谢物的鉴定、可能的中间体的利用以及相关基因的基因组学分析，Gordonia sp.对菲的降解。SCSIO19801 被提议通过水杨酸盐代谢途径发生。这是Gordonia菲降解途径的第一份报告物种。此外，Gordonia sp。SCSIO19801 可以使用其他芳香族化合物作为碳和能量的唯一来源。这些特征表明Gordonia sp。SCSIO19801 可用于开发在海洋环境中生物降解石油烃的有效方法。
