“…Earthworms living on the surface of the soil can produce a rich amount of humic substances that stimulate the ion exchange process in heavy metals by forming hydrophobic mediated interaction between heavy metals and MTs protein of earthworm (Binding score: Cd=Cr = Cu = 980, and Zn = 372.) which was evident through docking process (Yuvaraj et al, 2021).…”

Alterations of soil characteristics that result in reduction in ecosystem services invariably cause soil quality degradation. Such changes could be caused due to a variety of stressors, which might be physical, chemical, or biological and come from both anthropogenic and natural causes. Out of the wide variety of soil pollutants, agrochemicals contaminate soil biota the most. Numerous research’ findings have confirmed that soil has been the most preferred site for the disposal of xenobiotics and therefore is likely to be the source of contamination for other natural resources like ground and surface waters. The ecological risk associated with contaminated soils depends on many physicochemical and biological processes that govern the transport and transformation of pesticides. Nevertheless, the persistence of pesticides in soil is a serious threat to both below and above ground organisms which play key roles in sustaining soil functions. One of the viable methods to decontaminate soil is by utilizing living soil biota selectively. This process called. Bioremediation has traditionally been employed to remove chemical residues from soil or to lessen their toxicity levels. Although microbes have been extensively used for bioremediation, chemical breakdown and remediation are significantly aided by certain dominant soil fauna, such as earthworms. Since they modify soil quality, earthworms are regarded as soil engineers. Earthworms can participate in the degradation of pesticide residues, either directly through the release of detoxifying enzymes in their gut or indirectly through their positive influence on microbial populations which could degrade pesticides. The earthworm supported pesticide degradation is largely confined to the gut microenvironment and the soil processed by the worms. The impact of earthworm species on pesticide degradation is widely variable which could be related to their feeding habits and microhabitats. Molecular docking studies have provided evidence in support of binding of organic molecules with agrochemicals. High level of organic matter in soil is expected to increase the binding of hydrophobic pesticides to organic ligands with consequent reduction in their bioavailability to microorganisms and increasing their persistence. Activities of earthworms is likely to induce growth of aerobic microbes capable of pesticide degradation. Among the various earthworm species, Lumbricus terrestris, Perionyx excavatus and Metaphire posthuma have shown promising results as remediating agents of pesticides contaminating farm soils. The present article focuses on the remediation process of hazardous pesticide polluted soil using biological agent like earthworm. This approach may be both efficient and environmentally beneficial.

“…An added justification to the above generalization was brought by Saravanan et al (2021) in their investigation on the adsorptive characteristics of reusable magnetic nanoparticles decorated co‐cultured fungal biomass that adsorbs toxic Cr (VI) ions from aqueous environments. In respect of heavy metal detoxification from agricultural field soil, recent study by Yuvaraj et al (2021) describes the use of metallothionein proteins from earthworm to mediate detoxification of heavy metals such as Cu, Cd, Zn and Cr. However, very few studies make use of micro‐organisms to carry out this task.…”

Aim Tomato‐associated plant‐growth‐promoting rhizosphere bacteria were screened for effective antagonistic activity against the fungal vascular wilt pathogens; tolerance to heavy metals; and enhancing the bioavailability of iron for tomato plants through in vitro and in vivo approaches. Methods and Results Among the 121 rhizobacteria screened for siderophores, 25 isolates were observed to be siderophore producers and out of these, seven isolates chelate copper and iron thus exhibiting in vitro antagonism against the virulent strains of Fusarium oxysporum f. sp. lycopersici MTCC10270 (Fol), Fusarium equiseti MFol and Sarocladium sp. SWL isolated from infected tomatoes. Pseudomonas stutzeri KRP8 was identified to be the most potent strain among the siderophore producers and its siderophores were chemically characterized by mass spectra as metal bound and metal‐free forms. Upon bio‐inoculation of fortified bacterial consortium (siderozote) into the rhizosphere of vermiculite pot cultured tomatoes supplied with varying concentrations of iron and copper ions, we observed in planta growth improvements, antagonism, enhancement of bioavailability of iron and heavy metal tolerance using Inductively Coupled Plasma‐Optical Emission Spectrometry. Conclusion and Significance of the Study Our rhizobacterial consortium provides an opportunity for soil reclamation through an ecofriendly method for a heavy metal‐free agricultural landscape.

“…Earthworms are one of the most examined animal groups in terms of their capacity to accumulate metallic elements. Several studies have shown that earthworms can accumulate Zn, Hg, Pb, Cd, and Cu, in their bodies from contaminated soil [ [54] , [55] , [56] ]. Although the efficiency of these pathways can be affected, earthworms primarily collect HMs by digesting soil particles and secondarily via cutaneous uptake from the pore-water [ 57 ].…”
