Coupled remediation strategies applied to an petrochemical sludged in La Plata, Argentina Raw sequence reads

During extraction, transport, storage (upstream) and refined (downstream) of oil crude huge amounts of waste are generated, as oily sludge. Oily sludge is classified as a priority environmental pollutant by the US Environmental Protection Agency (US EPA, 1986). Before their final disposal, oily sludge must treat for reaching waste disposal standards by current local regulations. (Hu et al., 2013). Oxidizing reagents, such as persulfate ion (Gou et al., 2020; Marina Peluffo et al., 2018), Fenton's reagent (Sivagami et al., 2019) and ozone (Chen et al., 2020) had revealed good outcome for oily sludge treatment. Also bioremediation process have also been used successfully for treating sludge and petroleum hydrocarbons contaminated sediments, as bioaugmentation (Guarino et al., 2017; Ma et al., 2015; Mishra et al., 2001), bioestimulation ,(Roy et al., 2018; Sarkar et al., 2016) and compost (Aguelmous et al., 2020). Recent research has shown that the combination of chemical oxidation techniques followed by bioremediation treatments in contaminated soil, provides greater efficiency and removal contaminants. In view of the this, the goals of this project was to evaluate the impact of these strategies on bacterial and fungal communities and on removal contaminants on oily sludged.
