Abundance, dynamics, and biogeographic distribution of seven Polycyclic aromatic hydrocarbon dioxygenase gene variants in coastal sediments of Patagonia

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.
