“…Although soil half‐lives of pesticides range from a few days to weeks, in principle, residues of many pesticides (i.e., herbicides) are found ubiquitously in soil, groundwater, and even surface water. It is therefore important to clear exogenetic pesticide ingredients from the environment, particularly their biodegradation products . Additionally, common organic compounds include polycyclic aromatic hydrocarbons (PAHs), antibiotics, phthalates, and horfaces in soil.…”

Efficient noninvasive techniques are desired for repairing organic‐contaminated soils. Bioelectrochemical technology, especially microbial fuel cells (MFCs), has been widely used to promote a polluted environmental remediation approach, and applications include wastewater, sludge, sediment, and soil remediation. Soil MFC remediation has been of significant concern in recent years, and thus, several aspects, including reactor configuration, electrode materials, soil conductivity, mass transfer, and microbial activity, are reviewed. Recent studies and key issues of soil MFCs and perspectives of organic‐contamination remedial application are summarized, with the aim of assisting environmental scholars and engineers to gain a comprehensive understanding of MFC remediation. Insights are also offered on how to extend applications to help soil MFC remediation technology to advance and be applied in the future on a large scale.

“…La implementación de lombrices para la biorremediación es una técnica novedosa que ha mostrado que las capacidades de asimilación de metales por vía digestiva es prácticamente independiente del pH del suelo [27]. A través de las secreciones mucilaginosas y la transformación de materia orgánica, las lombrices incrementan la actividad microbial y la disponibilidad de los nutrientes, de igual manera se ha reportado que las lombrices pueden estimular las bacterias, hongos y especies relacionadas con la degradación del pentaclorofenol [28][29][30][31][32].…”

<p>Dentro de las actividades que alteran la composición del suelo está la minería, que causa el aumento de daños visibles al suelo mediante la creación de minas a cielo abierto, escombreras, estanques de residuos y otras instalaciones de minas. El objetivo principal de este trabajo fue evaluar el efecto de la lombriz roja californiana sobre el crecimiento de microorganismos en suelos contaminados con mercurio en el municipio de Segovia, Antioquia. Estos suelos representan una problemática importante debido a la acumulación de mercurio en exceso que ocasiona la pérdida de la calidad del suelo. Para este estudio se tomaron cuatro tratamientos en diferentes concentraciones de mercurio y un tratamiento más como blanco con lombrices rojas californianas <em>(Eisenia foetida). </em>Para esto, se evaluó el crecimiento de microorganismos a través de diferentes cultivos en el laboratorio, encontrando un crecimiento satisfactorio de los mismos luego de 25 y 90 días de tratamiento. De acuerdo al comportamiento observado, se evidencia una inmovilización del mercurio y una adaptación de los microorganismos al suelo contaminado, mostrando un aumento significativo de estos con el transcurso del tiempo.</p>

“…It is known to bioaccumulate, to be very toxic, and to generate harmful consequences in soil and aquifer environments because of its low biodegradability and chemical stability (Puglisi et al 2009;Li et al 2015). Therefore, searching for a cost-effective and environmentally friendly approach to eliminate this contaminant is now a worldwide priority.…”

“…Chen et al (2012) used the terminal restriction fragment length polymorphism (T-RFLP) method to study the anaerobic degradation of PCP by indigenous microorganisms in paddy soils collected from typical sites in southern China. Furthermore, DNA-based stable isotope probing (SIP) was applied to explore the key microorganisms responsible for PCP mineralization in paddy soils (Tong et al 2015;Li et al 2015).…”

Pentachlorophenol (PCP) is a common persistent pesticide in soil that has generated a significant environmental problem worldwide. Therefore, anaerobic degradation of PCP by the soil indigenous microbial community has gained increasing attention. However, little information is available concerning the functional microorganisms and the potential shifts in the microbial community associated with PCP degradation. In this study, we conducted a set of experiments to determine which components of the indigenous microbial community were capable of degrading PCP in soils of two land use types (upland and paddy soils) in southern China. Our results showed that the PCP degradation rate was significantly higher in paddy soils than that in upland soils. 16S ribosomal RNA (rRNA) high-throughput sequencing revealed significant differences in microbial taxonomic composition between the soil with PCP and blank (soil without PCP) with Acinetobacter, Clostridium, Coprococcus, Oxobacter, and Sedimentibacter dominating the PCP-affected communities. Acinetobacter was also apparently enriched in the paddy soils with PCP (up to 52.2 %) indicated this genus is likely to play an important role in PCP degradation. Additionally, the Fe(III)-reducing bacteria Clostridium may also be involved in PCP degradation. Our data further revealed hitherto unknown metabolisms of potential PCP degradation by microorganisms including Coprococcus, Oxobacter, and Ruminiclostridium. Overall, these findings indicated that land use types may affect the PCP anaerobic degradation rate via the activities of indigenous bacterial populations and extend our knowledge of the bacterial populations responsible for PCP degradation.
