Distinct microbial community along the chronic oil pollution continuum of the Persian Gulf converge with oil spill accidents

Abstract The Persian Gulf, hosting ca. 48% of the world’s oil reserves, has been chronically exposed to natural oil seepage. Oil spill studies show a shift in microbial community composition in response to oil pollution; however, the influence of chronic oil exposure on the microbial community remai...
