| contents | Enhanced anaerobic bioremediation of oil-contaminated intertidal sediment with a combination of anaerobically-synthesized rhamnolipids and sulfate. Jiang, Lijia Hao, Qian Li, Shichen Jin, Shidi Atakpa, Edidiong Okokon Ma, Yinghui Zhang, Chunfang Ding, Haitao Biodegradation, Environmental Glycolipids Geologic Sediments Sulfates Anaerobiosis Polycyclic Aromatic Hydrocarbons Water Pollutants, Chemical Petroleum Pollution Petroleum Oil pollution in intertidal sediments is a serious environmental issue. The anoxic environment of the sediment hinders the decomposition of hydrophobic organic pollutants. Conventional bioremediation methods, such as the sole addition of electron acceptors, have struggled to achieve high efficiencies because of the low solubility of oil pollutants. Herein, the combination of anaerobically-synthesized rhamnolipids and electron acceptor was evaluated for the bioremediation of oil-polluted sediments. Meanwhile, the key genes involved in CNPS cycling were detected to understand the biogeochemical processes and the complex interactions between microbial metabolism, nutrient availability, and pollutant degradation. After the bioremediation, the combination of rhamnolipids and sulfate significantly enhanced the removal of polycyclic aromatic hydrocarbons (74.8 ± 1.4%). On day 270, the polyphenol oxidase activity of rhamnolipids and sulfate with rhamnolipids treatments reached 20870.1 ± 1988.7 mg/(kg·h) and 22373.8 ± 970.1 mg/(kg·h), respectively, which was significantly higher (P |
