“…In conclusion, the results demonstrated that the biomix prepared with an Andisol and biostimulated with NPK nutrient can be recommended in biobeds as a viable alternative to chlorpyrifos dissipation, thereby avoiding the likelihood of soil and water contamination (Tortella et al 2010 ). By contrast, and taking into account that biostimulation of organicpollutant-degrading microorganisms by adding volatile organic compounds such as terpenes has been used to increase pollutant biodegradation in contaminated soils (Bento et al 2005 ;Tyagi et al 2011 ;Dudášová et al 2012 ), Tortella et al ( 2013d ) studied the effect of the terpenes α-pinene, eucalyptol, and limonene, individually and as mixtures, on atrazine biodegradation and on biological activity in a biobed biomixture. The results showed that terpenes added individually at relatively low concentrations (50 μg/kg) signifi cantly enhanced atrazine degradation and biological activity during the fi rst days of incubation.…”

The widespread use of pesticides for agricultural and for nonagricultural purposes worldwide has resulted in the presence of pesticide residues in various environmental matrices. The occurrence of pesticide residues in surface waters, groundwater, and large volumes of soil is mainly due to the inadequate management of these compounds. In this context, a biobed system was developed in Sweden in response to the need for a simple and effective way to minimize environmental contamination from pesticide manipulation, particularly when fi lling the spraying equipment, a typical point source of contamination. Biobeds are based on the adsorption and degradation potential of organic biomixtures composed of top soil, peat, and straw that fi lls a deep hole in the ground and a grass layer that covers the surface. Recently, the use of biobeds has expanded to other countries in Europe and Latin America. In Chile, four biobeds similar to the European ones have been installed, making this country a pioneer in this type of decontamination system. This chapter gives a general overview of biobeds technology and the advances in research at laboratory scale related to the treatment of pesticide residues in a biobed system in Chile.

“…Biosurfactants such as rhamnolipid and surfactine, which are environmentally friendly and might even promote plant growth, should receive more attention (Santa Anna et al ., ; Zhu & Zhang, ; Souza et al ., ). Increase co‐metabolism of POPs by providing co‐metabolites or inducers. Many studies have shown that synthetic or natural inducers such as biphenyl, terpenes, linoleic acid and salicylate enhanced the biodegradation of various POPs (Chen & Aitken, ; Yi & Crowley, ; Dudášová et al ., ). Input of endophytic bacteria, such as Rhizobium , to improve plant growth or degrading bacteria and or degrading saprotrophic fungi in contaminated soil. For example, dual inoculation of alfalfa with G. caledonium and Rhizobium meliloti showed great potential in the remediation of soil contaminated with PCBs (Cui & Li, ; Teng et al ., , ).…”

Concern about soil contamination by persistent organic pollutants (POPs) that originate from intensive anthropogenic activities has now become a priority in industrialized countries. Some of these compounds can accumulate in the environment and threaten the development of living organisms because of their acute toxicity, mutagenicity and carcinogeneity. Among remediation methods for polluted soil, arbuscular mycorrhizal fungi (AMF)‐assisted phytoremediation is an attractive approach to plant‐based environmental remediation. Arbuscular mycorrhizal associations are important in the restoration of degraded ecosystems because of the benefits to their symbiotic partners. Arbuscular mycorrhizal fungi are not only able to facilitate plant establishment and survival in POP‐contaminated soil by protecting plants against the phytotoxicity of POPs, but also enhance soil bioremediation by stimulating telluric microbial activity and by improving soil structure. This phytotechnology, however, is still in its infancy and there has been little research on aged‐contaminated soils. Its in situ effectiveness remains to be proved. This review summarizes current knowledge about the effect of POPs on the establishment and functioning of arbuscular mycorrhizal symbiosis and its contribution to the phytoremediation of POP‐polluted soil. It focuses on recent developments that aim to improve the efficiency of AMF‐assisted phytoremediation in the dissipation of POPs and future directions. Highlights Arbuscular mycorrhizal fungi (AMF) provide a means of plant‐based environmental clean‐up. AMF‐assisted phytoremediation is based on the synergistic actions of plants and telluric microorganisms. Research is in progress to improve efficiency of this phytotechnology and management of the biomass produced. Development of integrated approaches that combine land remediation with biomass conversion processes is required.

“…Plants rich in terpene contents belong to this group. Many studies including our research described the stimulation effects of ivy leaves, pine needles [82], eucalyptus leaves, tangerine, and orange peel [83][84][85] on biodegradation of hydrophobic pollutants. Potential use of natural plant matrices containing terpenes in the bioremediation of PCBs was studied in our previous works [15,19,81].…”

The chapter describes the aspects of bioremediation that are related to survival and metabolism of bacterial degraders in the adverse environment contaminated with dangerous hydrophobic chemicals, polychlorinated biphenyls (PCBs). Successful environment decontamination requires bacterial strains that possess appropriate enzymes and are able to degrade particular contaminants. This chapter deals mainly with the adaptation mechanisms that allow bacteria to decrease toxic effects of the dangerous compounds on cytoplasmic membrane as the first contact point of pollutants and the bacterial cell. Many responses have been observed in bacteria that counteract the effects of toxic environmental organic pollutants: saturation-rigidification of cell membrane, cis/trans isomerization of fatty acids, increased content of cyclopropane fatty acids, and changes in branched fatty acids and cardiolipin, production of stress proteins, and elimination of toxic compounds using efflux pump. The study of these mechanisms is the first step in selection of appropriate resistant bacterial strains for bioremediation applications. Next steps should include study of degradation potential and efficacy of the most resistant strains. Setting up suitable experimental systems to examine the cell responses to toxic environmental organic pollutants in the adverse environment and optimal conditions for metabolism of bacterial degraders are important issues in the current bioremediation research agenda.
