“…Bioremediation technologies have been developed for soils and coastal areas using the addition of nutrients and microbes [10][11][12][13]. However, it is known that biodegradation efficiencies of petroleum hydrocarbons in soil can be limited by physicochemical as well as biological factors, such as nutrients, pH, temperature, moisture, oxygen, soil properties, and contaminant concentration, number and type or species of microorganisms [14][15][16][17][18][19][20][21]. Also, oil spills result in an imbalance in the carbon-nitrogen ratio at the spill site, because crude-oil is essentially a mixture of carbon and hydrogen.…”

The objective of this study was designed to evaluate the effects of biostimulation and bioaugmentation amendment agents (NPK fertilizer, Tween 80 and mixed culture) on the bioremediation of tropical soil samples artificially contaminated with Weathered Bonny Light Crude Oil (WBLCO). Response Surface Methodology (RSM) with Box Behnken Design (BBD) was used with three levels and three factors of NPK fertilizer (2 -6 g), Tween 80 (5 -15 mg/l) and mixed culture (0.5 -1.5 g/l) as independent variables and WBLCO removal as dependent variable (response) in a six weeks remediation period. The results showed that the rate of WBLCO removal generally increased with increase in the amount of NPK fertilizer, Tween 80 and mixed culture (biomass), respectively. A statistically significant (P < 0.0001) second-order quadratic regression model for WBLCO removal (using design-expert statistical program (v. 6.0.8)) with a coefficient of determination, R (=0.9996) was obtained. Numerical optimization technique based on desirability function was carried out to optimize the bioremediation process. The optimum values for biostimulation and bioaugmentation amendment agents to achieve a predicted maximum WBLCO removal of 84.88 percent were found to be: NPK fertilizer, 4.25 g; Tween 80, 10.22 mg/l and mixed culture, 0.46 g/l. At this optimum point, the observed WBLCO removal was found to be 83.79 percent. The statistical analyses and the closeness of the experimental results and model predictions show the reliability of the regression model and thus, biostimulation and bioaugmentation of indigenous microbial density and activity can reduce remediation period of petroleum hydrocarbon contaminated environment and subsequently the cost of remediation.

“…Increase in dissolved CO 2 in a groundwater plume indicated the existence of biodegradation. Namkoong et al (2002) also verified that the degradation of TPH was related to microbial respiration and the results were expressed as CO 2 production. In order to evaluate hydrocarbons biodegradation in soil, the increase of microbial population after 45-days assay was monitored (Fig.…”

“…According to Mason review for composting modeling (Mason 2006), first-order kinetics model with empirical corrections for temperature, moisture, oxygen concentration and free air space are generally successful in predicting the evolution of dynamic state variables (temperature, solids, moisture, oxygen and carbon dioxide concentration). Furthermore, using the first-order kinetics model for degradation of organic materials and petroleum hydrocarbons has been previously justified by several authors (Jorgensen et al 2000;Hwang et al 2006;Namkoong et al 2002;Van Gestel et al 2003), among others. So, the first-order kinetics model (Haug 1993;Mason 2006;Petric and Selimbasic 2008) with empirical corrections for temperature, moisture, oxygen concentration and free air space was considered as follows for biodegradation process and the effects of the other factors were ignored:…”

“…Up to date, several bioremediation techniques have been reported to clean up soils contaminated with hazardous chemicals (Abdulsalam et al 2011;Adams and Guzmán-Osorio 2008;Bento et al 2005;Chaineau et al 2005;Fountoulakis et al 2009;Gallego et al 2001;Jorgensen et al 2000;Megharaj et al 2011;Yousefi Kebria et al 2009;Zhao et al 2010). Due to low capital and operating costs, simplicity of operation and design, and relatively high treatment, composting technique is preferred in comparison with the other methods (Namkoong et al 2002;Van Gestel et al 2003).…”

“…Furthermore, it has been demonstrated that composting could be employed as an effective method for remediation of oil-contaminated soils (Antizar-Ladislao et al 2004;Al-Daher et al 1998;Bento et al 2005;Freeman and Harris 1995;Hwang et al 2006;Megharaj et al 2011;Namkoong et al 2002;Van Gestel et al 2003). Up to now, various experimental studies have been accomplished for remediation of oil-contaminated soils by composting.…”

The main scope of this work is applying an aerobic composting model for remediation of petroleum hydrocarbon-contaminated soil. For this purpose, the reaction kinetics was integrated with the mass and energy balances over the composting system. Literature pilot scale data for bioremediation of diesel oil-contaminated soil was used for model validation. Comparisons of simulation results with experimental data for diesel concentration and oxygen concentration showed good agreement during the remediation process. With validated model for bioremediation of diesel oil-contaminated soil, the influence of amendment type, bulking agent, amendment/soil ratio, bulking agent/soil ratio, moisture content and airflow rate were investigated on diesel biodegradation. The simulation results showed that maximum degradation of diesel occurred in the presence of yard waste as amendment. Furthermore, addition of bulking agent (wood chips) increased the diesel degradation about 6 %. In presence of yard waste as amendment and wood chips as bulking agent, the optimal values for maximum remediation were amendment/soil ratio (2.5 kg kg -1 ), bulking agent/soil ratio (2.25 kg kg -1 ), initial moisture content (62.5 %) and airflow (0.520 m 3 day -1 kgBVS -1 ).
