Remediation of petroleum-contaminated soil after composting by sequential treatment with Fenton-like oxidation and biodegradation

Bioremediation of Pyrene-Contaminated Soils Using Biosurfactant

“…Lu et al also studied pyrene biodegradation in contaminated soil without any biosurfactant addition. The removal efficiency for initial pyrene concentrations of 13, 28, 61, 121, 171 and 236 mg/kg ranged between 47-55% during 50 days (30), which were less than the amounts obtained in the current study for samples containing biosurfactant, but were similar to those without any biosurfactant in the same reaction times. A possible reason for pyrene removal in samples without any biosurfactant addition, other than inherent ability of bacterial strains to metabolize some of the pyrene content and a little solution of pyrene in the reaction medium, can be referred to production of exopolymeric substances (EPS) from the present bacteria and emission of EPS to the solution after they died.…”

Electrochemical pretreatment of heavy oil refinery wastewater using a three-dimensional electrode reactor

“…Members of a homologous series (namely, compounds that contain the same heteroatom and number of rings plus double bonds, but different number of CH 2 groups) easily selected and identified from a list of all observed ion masses. The homologous series were detected using the software programmed by Analysis Center, China University of Petroleum [22]. The pollutant molecules are commonly described by a Z value.…”

Bioremediation of crude oil-contaminated soil: Comparison of different biostimulation and bioaugmentation treatments

“…During the past decade, bioremediation of petroleumcontaminated soil has been a hot issue in environmental research, and many bioremediation strategies have been developed and improved to clean up soils polluted with petroleum and its derivatives [1][2][3]. Bioremediation is an efficient, economic and versatile alternative to physiochemical treatments [4].…”
