A phenazine-1-carboxylic acid (PCA)-degrading bacterium, strain DP58, was isolated from pimiento rhizosoil. Based on morphology, physiologic tests, 16S rDNA sequence, and phylogenetic characteristics, it was identified as Sphingomonas sp. The PCA-degradation experiments were conducted both in Luria-Bertani and inorganic salt medium at 28 degrees C. The relationship between bacterium growth and PCA degradation suggested that strain DP58 could use PCA as the sole source of carbon and nitrogen and was able to completely degrade PCA in 40 hours. Newly isolated strain DP58 represents the first bacterium that can degrade PCA.
从辣椒根际土壤中分离出一株能够降解吩嗪 -1- 羧酸（PCA）的细菌，菌株DP58。基于形态学、生理测试、16S rDNA序列和系统发育特征，将其鉴定为鞘氨醇单胞菌属。在28℃下于Luria - Bertani培养基和无机盐培养基中进行PCA降解实验。细菌生长与PCA降解之间的关系表明，菌株DP58可以将PCA用作唯一的碳源和氮源，并能够在40小时内完全降解PCA。新分离的菌株DP58是第一株能够降解PCA的细菌。
