“…Chu and Chan (2003) studied the mechanism of the surfactant-aided soil washing system for hydrophobic and partial hydrophobic organic compounds. Other works have aimed at the effect of rapeseed oil on the degradation of polyclyclic aromatic hydrocarbons in soils by Rhodococcus wratislaviensi (Pizzul et al, 2007) and with degradation of polycyclic aromatic hydrocarbons by free and nanoclayimmobilized manganese peroxidase from A. discolor (Acevedo et al, 2010).…”

Worldwide use of pesticide has increased dramatically during the last two decades. As a consequence, pesticide residues and their transformation products are frequently found in groundwater and surface waters. This review summarizes information about polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), some chlorophenols; it mainly empathizes on pesticides, their incorporation into the environment, microorganisms involved in their degradation and, some physicochemical aspects of pesticides behavior in soils. Details about residues of pesticides in groundwater and superficial water found in some foreign countries and in Chile are reported, as well. The fungal degradation of organic pollutants (xenobiotics) is considered as an effective method to remove these pollutants from the environment by a process which is currently known as bioremediation. Therefore, the degradation of pesticides by soil microorganisms with particular attention to white-rot fungi is also addressed. Finally, a simple and effective system (biobed) to minimize environmental contamination from pesticide manipulation, especially when filling the spraying equipment, a typical point source of contamination, is presented here.

“…WRF can degrade a large variety of otherwise degradation-resistant pollutants as the result of the production of extracellular enzymes, principally laccase and peroxidases (D'Annibale et al 2005;Baborova et al 2006;Michniewicz et al 2008;Acevedo et al 2010), and intracellular enzymes, which are highly reactive. In the case of TCE, the intracellular cytochrome P450 system is responsible for the degradation (Marco-Urrea et al 2008a).…”

Extracellular radicals produced by Trametes versicolor under quinone redox cycling conditions can degrade a large variety of pollutant compounds, including trichloroethylene (TCE). This study investigated the effect of the agitation speed and the gas-liquid phase volume ratio on TCE degradation using central composite design (CCD) methodology for a future scale-up to a reactor system. The agitation speed ranged from 90 to 200 rpm, and the volume ratio ranged from 0.5 to 4.4. The results demonstrated the important and positive effect of the agitation speed and an interaction between the two factors on TCE degradation. Although the volume ratio did not have a significant effect if the agitation speed value was between 160 and 200 rpm, at lower speed values, the specific pollutant degradation was clearly more extensive at low volume ratios than at high volume ratios. The fitted response surface was validated by performing an experiment using the parameter combination in the model that maximised TCE degradation. The results of the experiments carried out using different biomass concentrations demonstrated that the biomass concentration had a positive effect on pollutant degradation if the amount of biomass present was lower than 1.6 g dry weight l(-1). The results show that the maximum TCE degradation was obtained at the highest speed (200 rpm), gas-liquid phase volume ratio (4.4), and a biomass concentration of 1.6 g dry weight l(-1).

“…Manganese peroxidase (MnP) produced by Anthracophyllum discolor, a Chilean white rot fungus, was immobilized on nanoclay obtained from volcanic soil and its ability to degrade PAHs compared with the free enzyme was evaluated [37]. The immobilized enzyme was able to degrade pyrene (> 86 %), anthracene (> 65 %), alone or in mixture, and to a less extent fluoranthene (< 15.2 %) and phenanthrene (< 8.6 %).…”

“…In addition, immobilized MnP shows an increased stability to high temperature, pH and time storage, as well as an enhanced PAHs degradation efficiency in soil. All these characteristics may suggest the possible use of nanoclay-immobilized MnP from A. discolor as a valuable option for in situ bioremediation purposes [37].…”

Abstract.Reactions proceeding at ambient temperature very promptly and selectively, as it occurs in live organisms, imitation of the wildlife processes, and, eventually, study of mechanism of enzymes action are important challenges of contemporary chemistry. This short review gives information on recent achievements in the field of enzymatic catalysis of oxidation of hydrocarbons. The literature material was gathered using the Thomson Reuters electronic database (Web of Science) and mostly covers the last decades.
