“…In the present study, earthworms encouraged cultivable bacteria and actinomyces (Figure 3), thus improving soil basal respiration and microbial biomass ( Figure 4) and increasing the soil microbial richness and evenness (Table S1 and Figure S1). It might be explained by earthworm bioturbation which augments soil porosity and oxygenation, increasing microbial activities and access to atrazine (Chachina et al, 2016). In addition, the mucus, urine and cast of earthworms are M A N U S C R I P T…”

Effects of two ecological earthworm species on atrazine degradation performance and bacterial community structure in red soil

Vermicomposting is an effective and environmentally friendly approach for eliminating soil organic contamination. Atrazine is one of the most commonly applied triazinic herbicides and frequently detected in agricultural soils. This study investigated the roles and mechanisms of two earthworm species (epigeic Eisenia foetida and endogeic Amynthas robustus) in microbial degradation of atrazine. Both earthworms accelerated atrazine degradation performance from 39.0% in sterile soils to 94.9%-95.7%, via neutralizing soil pH, consuming soil humus, altering bacterial community structure, enriching indigenous atrazine degraders and excreting the intestinal atrazine-degrading bacteria. Rhodoplanes and Kaistobacter were identified as soil indigenous degraders for atrazine mineralization and stimulated by both earthworm species. A. robustus excreted the intestinal Cupriavidus and Pseudomonas, whereas Flavobacterium was released by E. foetida. This study provides a comprehensive understanding of the distinct effects of two earthworm species on soil microbial community and atrazine degradation, offering technical supports to apply vermicomposting in effective soil bioremediation.

“…The vermiremediation method is not always successful in destroying or removing residual, heavy and hydrocarbons in contaminated soil. However, there is some evidence that this remediation is able to degrade such oil [1]. In this paper, the available compost reactor has been constructed from a plastic box, the length, width and height of which are 0.49 m, 0.30 m and 0.35 m, respectively.…”

“…It has been described that this approach involves the use of earthworms to bioaccumulate the contaminants within their bodies and biodegrade or bio-transform them into safe products with the assistance of enzymes. Chachina et al [1] reported that the worms host microbes that are able to biodegrade chemicals within their gut. They concluded that in petroleum contaminated soil with petroleum concentration of 20-60 g/kg, 99% of hydrocarbons content decreased after 22 weeks in the presence of Eisenia fetida.…”

The role of vermiremediation technique has been accepted all over the world for many years to reduce the concentrations of pollutant in the contaminated soil to acceptable levels. However, limited study has been found in the case of Kuwaiti oil contaminated sand using earthworms. This paper address the potential of decomposing petroleum hydrocarbons in terms of total petroleum hydrocarbon (TPH) present in Kuwaiti oil contaminated sand ranging from 5000 to 25,000 mg/ kg using earthworms (Eisenia fetida). It was observed that the TPH of < 5000 mg/kg was not harmful for the survival of earthworms, nevertheless TPH of 10,000 mg/kg reduced their survival to 50%. Moreover, the results indicate that that vermiremediation could effectively reduce the TPH of about 5000 mg/kg every 5 weeks. This study suggested that the crude oil could be consider as one of the main challenging for the survival of earthworms, therefore several factors such as type of soil, moisture content, temperature, organic matter content and pH need to maintain and enhance during the remediation process to support the earthworm's activity.

“…These combined technologies open new possibilities for soil remediation in a holistic approach, considering soil-earthworm-plant-microbial interactions in the ecological context of the polluted soil. Eisenia fetida is a good candidate as a vermiremediator ( Chachina et al., 2016 ; Suthar, 2008 ) and has also been widely used as an indicator of soil health ( Irizar et al., 2015a ; Shin et al., 2007 ).…”

Gentle Remediation Options (GROs), such as biostimulation, bioaugmentation, phytoremediation and vermiremediation, are cost-effective and environmentally-friendly solutions for soils simultaneously polluted with organic and inorganic compounds. This study assessed the individual and combined effectiveness of GROs in recovering the health of a soil artificially polluted with hexavalent chromium [Cr(VI)] and lindane. A greenhouse experiment was performed using organically-amended vs. non-amended mixed polluted soils. All soils received the following treatments: (i) no treatment; (ii) bioaugmentation with an actinobacteria consortium; (iii) vermiremediation with Eisenia fetida ; (iv) phytoremediation with Brassica napus ; (v) bioaugmentation + vermiremediation; (vi) bioaugmentation + phytoremediation; and (vii) bioaugmentation + vermiremediation + phytoremediation. Soil health recovery was determined based on Cr(VI) and lindane concentrations, microbial properties and toxicity bioassays with plants and worms. Cr(VI) pollution caused high toxicity, but some GROs were able to partly recover soil health: (i) the organic amendment decreased Cr(VI) concentrations, alleviating toxicity; (ii) the actinobacteria consortium was effective at removing both Cr(VI) and lindane; (iii) B. napus and E. fetida had a positive effect on the removal of pollutants and improved microbial properties. The combination of the organic amendment, B. napus , E. fetida and the actinobacteria consortium was the most effective strategy.
