Isomer mixture of dibenzopyrene biodegradation culture assays with microbial isolates from oil-contaminated sediment collected in the Chandeleur Islands, Gulf of Mexico on 2018-05-07

Biodegradation assays with five dibenzopyrene isomers including dibenzo[a,e]pyrene, dibenzo[a,h]pyrene, dibenzo[a,i]pyrene, dibenzo[a,l]pyrene, and dibenzo[e,l]pyrene were conducted in the presence of a consortium of microbes isolated from oil-contaminated sediment. Sediment cores were collected from the Chandeleur Islands in the Gulf of Mexico on May 7, 2018, in subtidal and marsh regions of the western side of the islands where oil from the Deepwater Horizon (DWH) oil spill remains buried. Data includes high throughput sequencing data demonstrating the changes to the individual microbial isolates as a result of the dibenzopyrene contamination.

本研究针对五种二苯并芘（dibenzopyrene）异构体开展生物降解实验，所涉异构体包括二苯并[a,e]芘（dibenzo[a,e]pyrene）、二苯并[a,h]芘（dibenzo[a,h]pyrene）、二苯并[a,i]芘（dibenzo[a,i]pyrene）、二苯并[a,l]芘（dibenzo[a,l]pyrene）与二苯并[e,l]芘（dibenzo[e,l]pyrene），实验在从受石油污染沉积物中分离得到的复合微生物菌群存在的条件下进行。沉积物岩心于2018年5月7日采自墨西哥湾尚德勒尔群岛（Chandeleur Islands）西侧的潮下带与沼泽区域，该区域仍埋藏有深水地平线（Deepwater Horizon, DWH）漏油事件泄漏的原油。本数据集包含高通量测序（high throughput sequencing）数据，该数据可反映二苯并芘污染导致的各微生物分离株的变化情况。
