“…Thus, the quick and effective removal of PAHs from the environment as well as reducing their adverse effects seems to be necessary. Three-and four-ring PAHs are in particular associated with soil particles, and due to their low aqueous solubility and high sorption properties, their removal from subsurface environments using traditional technologies, such as soil washing, conventional chemical oxidation or bioremediation, is inefficient 5 . In fact, their removal from fine soil particles is still a major challenge for geo-environments, because of the high variation in their hydraulic conductivity, a lot of specific contaminants, environmental and dynamic conditions, reversible geochemical processes, and the interactions between soil particles and contaminants 6,7 .…”

Effect of surfactant addition on persulfate-assisted electrokinetic remediation of pyrene-spiked soil was studied. The influence of effective factors including voltage, surfactant addition, moisture content, and persulfate concentration on the removal of initial pyrene concentration of 200 mg kg-1 were investigated. A complete pyrene removal was observed for voltage of 1 V cm-1 , saturated conditions, Tween 80 concentration of 20 mL kg-1 , and persulfate concentration of 100 mg kg-1 after 24 h, corresponding to pyrene mineralization of 61 %, based on TPH analysis. The experimental results were best fitted with pseudo-first-order kinetic model with correlation coefficient of 0.968 and rate constant of 0.191 min −1. The main intermediates of pyrene degradation were benzene o-toluic acid, acetic, azulene, naphthalene and decanoic acid. Finally, an unwashed hydrocarbon-contaminated soil was subjected to persulfate-assisted electrokinetic remediation, and a TPH removal of 38 % was observed for the initial TPH content of 912 mg kg-1 , under the selected conditions.

“…Therefore, improving techniques with compost application for most efficient PAH bioremediation is still a field of research, since the mechanisms underlying the observed effect of compost addition, e.g., the introduction of microorganisms, nutrients, primary substrates, or all of them, are not yet clear. Supplementing contaminated soils with various types of compost material or other organic supplements, e.g., yard waste compost (Carlstrom and Tuovinen 2003;Kästner and Mahro 1996;Kästner et al 1995;Winquist et al 2014;Wu et al 2013), spent mushroom substrate (Cajthaml et al 2002;Lau et al 2003;Reid et al 2002;Šašek et al 2003), animal manure (Atagana 2004;Wong et al 2002;Yuan et al 2009), and sludges (Hamdi et al 2006(Hamdi et al , 2007Petersen et al 2003), has been successfully applied in order to remove PAH; a detailed summary is given elsewhere (Loick et al 2009). For optimal PAH removal, fully rotted compost has often been found to be much more effective than fresh compost (Haderlein et al 2006;Plaza et al 2009), and mature compost is considered to provide available nutrients with low sorption potential for high-molecular-weight PAH (AntizarLadislao et al 2005;Hafidi et al 2008).…”

Polycyclic aromatic hydrocarbons (PAH) are toxic pollutants widely distributed in the environment due to natural and anthropogenic processes. In order to mitigate tar oil contaminations with PAH, research on improving bioremediation approaches, which are sometimes inefficient, is needed. However, the knowledge on the fate of PAH-derived carbon and the microbial degraders in particular in compost-supplemented soils is still limited. Here we show the PAH carbon turnover mass balance in microcosms with soil-compost mixtures or in farmyard fertilized soil using [(13)C6]-pyrene as a model PAH. Complete pyrene degradation of 100 mg/kg of soil was observed in all supplemented microcosms within 3 to 5 months, and the residual (13)C was mainly found as carbon converted to microbial biomass. Long-term fertilization of soil with farmyard manure resulted in pyrene removal efficiency similar to compost addition, although with a much longer lag phase, higher mineralization, and lower carbon incorporation into the biomass. Organic amendments either as long-term manure fertilization or as compost amendment thus play a key role in increasing the PAH-degrading potential of the soil microbial community. Phospholipid fatty acid stable isotope probing (PLFA-SIP) was used to trace the carbon within the microbial population and the amount of biomass formed from pyrene degradation. The results demonstrate that complex microbial degrader consortia rather than the expected single key players are responsible for PAH degradation in organic-amended soil.

“…The characteristics of wastewater from biodiesel factory, from which the fungus was isolated, can also impact its preference for biodiesel since this effluent contains high levels of oils and its microbiota can metabolize these compounds. The ability of fungi to biodegrade petroleum hydrocarbons has been extensively reported (Mancera-López et al, 2008;Soares Jr. et al, 2009;Winquist et al, 2014). On the other hand, biodiesel biodegradation studies have been conducted especially using bacteria (Yassine et al, 2013;Colla et al, 2014;Lisiecki et al, 2014, Souza et al, 2016, although fungi present high bioremediation potential.…”

Biodiesel is a clean renewable fuel used as alternative energy source to diesel and it is commercialized as a minor component in diesel blends. Similarly to diesel, biodiesel spill is a source of contamination for the ecosystem making necessary to provide effective remediation strategies. Bioremediation is a technology that has been applied with success to clean up hydrocarboncontaminated environments. In this study, fungal bioaugmentation strategy was compared with natural attenuation during bioremediation of a sandy soil contaminated with diesel, biodiesel and blends (B20 and B50). Respirometric assays simulating the contamination of soil were carried out in Bartha flasks used to measure microbial CO 2 production. Penicillium sp. AV4 isolated from the wastewater of a biodiesel factory has the ability to degrade the fuels and was used in bioaugmentation. After 111 days, CO 2 evolution demonstrated no significant difference in soil microbial activity between fungal augmentation and natural attenuation treatments for all fuels. The lack of influence of Penicillium sp. AV4 can be related to its inability to compete with soil microorganisms and/or increase its metabolic activity. During natural attenuation, B50 showed a higher CO 2 production, followed by the B100, B20 and diesel, which is less biodegradable. Therefore, from a biodegradation perspective, biodiesel could be more beneficial than diesel during bioremediation spill.
