A 3,5,6-trichloro-2-pyridinol (TCP)-degrading strain, T6, was isolated by continuous enrichment culture and identified as Ralstonia sp. based on morphological, physiological and biochemical tests as well as 16S rDNA sequence analysis. The bacterium metabolized 100 mg/L TCP within 12 h and 700 mg/L TCP in 80 h. A green metabolite, putatively identified as 3,6-dihydroxypyridine-2,5-dione, was detected. This is the first report of TCP-degrading isolate from the genus of Ralstonia. Strain T6 could potentially be employed in bioremediation of TCP.
一株可降解 3,5,6-三氯-2-吡啶醇（TCP）的菌株 T6 通过连续富集培养分离得到，并根据形态学、生理学和生物化学试验以及 16S rDNA 序列分析鉴定为恶臭假单胞菌属。该细菌在 12 小时内代谢 100mg/L 的 TCP，在 80 小时内代谢 700mg/L 的 TCP。检测到一种绿色代谢物，推测为 3,6-二羟基吡啶-2,5-二酮。这是首次从恶臭假单胞菌属中分离到可降解 TCP 的菌株。菌株 T6 可能在 TCP 的生物修复中得到应用。
