“…Concomitantly, progressive decrease in the pH was observed, this parameter reaching a value of pH 9.0 at day 35th and stabilizing between pH 8.0 and 8.5 for a long time. It is known from the literature [5] that the optimum temperature for the degradation of PAH by composting is between 40 and 45 • C, which represents the overlap point of the optimal con- ditions for mesophylic and thermophylic micro-organisms. In our process slightly higher temperatures were produced when biodegradation started.…”

“…Fungi possessing ligninolytic properties have been shown to be active in PAHs degradation [2,16] and, recently, the use of spent mushroom compost was used to demonstrate degradation of PAHs in soil samples spiked with known amounts of some PAHs [17]. The impact of composting strategies on the treatment in soils and waste contaminated with PAH was the subject of some recent reviews [5,18].…”

“…The United Kingdom, as well as Italy, takes the view that land should be cleaned to make it fit for its intended use. By contrast, other countries such as the United States and the Netherlands adopt a multifunctional approach whereby land must be fit for any use [5]. According to Italian regulatory guidelines, the maximum PAHs content in soils is 10 mg kg −1 for residential use and 100 mg kg −1 for industrial or commercial use [6].…”

This study deals with the biodegradation of the polycyclic aromatic hydrocarbons (PAH)s present in a soil contaminated by soot waste, characterised by a total PAHs content in the 200 mg kg −1 range. A challenging characteristic of the waste soil treated was its high alkalinity, with a pH of about 12.8. The waste came from a soot-contaminated area located in the industrial zone of Porto Marghera, Venice (Italy). The biodegradation process employed was the composting of the waste with sewage sludge and yard waste. The process was carried out on a pilot scale using a closed tank with forced aeration for a period of 60 days, followed by 70 days with natural aeration. The time evolution of the process was monitored by following the time change in the concentration of the 16 US-EPA PAHs, as well as temperature, pH, electrical conductivity, C and N contents. Also phytotoxicity parameters, such as the growth and respiration indexes, were monitored. An induction time of about 30 days was observed, which corresponded to the time required before observing a significant self-drop in the waste pH and an increase in mass temperature. Afterward, a progressive drop in the PAHs concentration was observed, up to reaching after 130 days an overall degradation percentage in the order of 68%. The degradation was more effective on rather low molecular weight PAHs (2-4 rings).

“…Benzo(a)pyrene with five benzene rings is considered as the most carcinogenic PAH-compound. PAHs are resistant to microbial degradation because of their low water solubility and complex structure with two or more fused benzene rings (Antizar-Ladislao et al, 2004). Johnsen and Karlson (2007) investigated the diffuse PAH contamination in surface soils and noticed that phenanthrene, fluoranthene, and pyrene can be degraded by soil microorganism, whereas, benzo(a)anthracene and benzo(a)pyrene are examples of more recalcitrant high molecular weight (HMW) PAHs that are biodegraded very slowly in soil.…”

Fungal enzyme production and biodegradation of polychlorinated dibenzo-p-dioxins and dibenzofurans in contaminated sawmill soil

Soils that are contaminated with the most recalcitrant organic contaminants, such as high molecular weight polyaromatic hydrocarbons (HMW PAH) and polychlorinated dibenzo-pdioxins and dibenzofurans (PCDD/F), cannot be degraded efficiently by conventional composting. The only available treatment method for these soils, which destroys the contaminants, is combustion at high temperature. This thesis examines three alternative fungal methods to treat these soils: 1) treatment with fungal enzymes, 2) treatment with fungal inoculum, and 3) fungal treatment used as a pre-treatment to improve the energy efficacy in combustion. Manganese peroxidase (MnP), which belongs to lignin-modifying enzymes (LME), was produced and used to treat PCDD/F-contaminated soil in the laboratory scale. Nevertheless, no degradation with a MnP preparation was observed, although a substantial amount of MnP activity was found in the soil still after 10 days of incubation. Both PAH-and PCDD/Fcontaminated soils were treated with fungal inoculum in the laboratory scale. HMW PAHs were degraded significantly more by the fungi than by the indigenous microbes alone in the laboratory experiments, where the PAH concentration of soil was 3500 mg kg -1 (sum of 16 PAH). Treatment with Phanerochaete velutina (inoculum) resulted to degradation of 96 % of 4-ring PAHs and 39 % of 5-and 6-ring PAHs in three months. With PCDD/F-contaminated soil, no degradation was observed in the control, but the degradation of PCDD/Fs with fungal treatments was significant (P. velutina: 62 %, Stropharia rugosoannulata: 64 % of WHO-TEQ value). Fungal treatment of PAH-contaminated soil was also applied in the field scale (2 t). However, both P. velutina (inoculum) and control treatment resulted in equal degradation in soil with lower PAH concentration (1400 mg kg -1 , sum of 16 PAH): 94 % of the 16 PAHs were degraded in three months. Fungal treatment was even applied as a pre-treatment for contaminated soil with high organic matter content, and which will be later combusted. In the pilot-scale (300 kg), 13 % degradation of the original organic matter content was obtained in 6 months. To conclude, fungal treatment is reasonable to apply for soils with organic contaminants that cannot be bioremediated by composting. With soils contaminated by chlorinated dioxins, this is always the case, but also PAH-contaminated soils with high total concentration or high proportion of HMW-PAHs. In addition, with fungal treatment the amount of organic matter in the soil can be reduced and the efficacy of the combustion process is improved.

“…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 ).
