Abstract
Novel polycyclic aromatic hydrocarbon dioxygenase gene variants were present in abundances similar to or higher than those of phnA1 from Cycloclasticus spp. at a chronically polluted subantarctic coastal marine environment in Patagonia. These novel gene variants were detected over a 6-year time span and were also present in sediments from temperate Patagonian sites.
摘要
新型多环芳烃双加氧酶基因变体的丰度与环丙沙星 spp. 的 phnA1 相似或更高，存在于巴塔哥尼亚长期污染的亚南极沿海海洋环境中。这些新型基因变体在 6 年的时间跨度内被检测到，也存在于来自温带巴塔哥尼亚地区的沉积物中。
