Bacteria involved in the sulfur cycle in tarballs collected from the Alabama Gulf Coast

Abstract Tarballs are formed from released or discharged crude oil containing sulfur compounds. A considerable amount and variety of sulfate-reducing bacteria (SRB) and sulfur-oxidizing bacteria (SOB) were identified in tarballs collected from the intertidal and supratidal zones of Alabama’s Gulf be...

Description
Summary:Abstract Tarballs are formed from released or discharged crude oil containing sulfur compounds. A considerable amount and variety of sulfate-reducing bacteria (SRB) and sulfur-oxidizing bacteria (SOB) were identified in tarballs collected from the intertidal and supratidal zones of Alabama’s Gulf beaches. Amplicon sequencing of the bacterial 16S rRNA gene showed that SRB were more abundantly distributed in the core than on the surface of tarballs, while no significant differences were observed in the distribution of SOB. To our best knowledge, this is the first report on the spatial distribution of diverse SRB and SOB in tarballs. Sulfate-reducing bacteria are more abundant in the core than on the surface of tarballs collected from two Alabama Gulf beaches.
