Systematic degradation process of petroleum hydrocarbons by an integrated bacterial consortium under bottom seawater and surface seawater environments
Dealing with oil spills is urgent, and bioaugmentation is a low-cost and environmentally friendly method. However, little research has been done on the remediation effect of bioaugmentation in oil-polluted environments with bottom seawater microorganisms. This work constructed the bottom seawater (S...

| Résumé: | Dealing with oil spills is urgent, and bioaugmentation is a low-cost and environmentally friendly method. However, little research has been done on the remediation effect of bioaugmentation in oil-polluted environments with bottom seawater microorganisms. This work constructed the bottom seawater (S) group and surface seawater environment (T) group to study the oil degradation ability and the microbial community successions tendency with the function of integrated bacterial consortium. After 50 days of bioaugmentation, the oil degradation rates of the S and T groups were 53.33% and 43.72%, which were 26.98% and 25.82% higher than that of natural restoration, respectively. Furthermore, the microbial community structure succeeded in the same direction under different environments after oil pollution and bioaugmentation, and the main classes were Gammaproteobacteria, Alphaproteobacteria. Precisely, Alcanivorax and Cycloclasticus played the primary roles in oil degradation under two different initial environments, and they were mainly affected by natural restoration and bioaugmentation, respectively. This work can contribute to a better base for bioaugmentation strategy development in the bottom seawater environment |
