“…The most important factor affecting bioremediation efficiency is site characteristics. Secondly, environmental factors such as water content, temperature, pH, nutrient availability, moisture content, and pollutant bioavailability can also hinder the efficiency of bioremediation ( Freitas et al, 2013 ; Azubuike et al, 2016 ; Khodaverdiloo et al, 2020 ; Leong and Chang, 2020 ). Apart from this, the bioremediation process is a complex system that is optimized and controlled by many factors.…”

Soil contamination with heavy metals (HMs) is a serious concern for the developing world due to its non-biodegradability and significant potential to damage the ecosystem and associated services. Rapid industrialization and activities such as mining, manufacturing, and construction are generating a huge quantity of toxic waste which causes environmental hazards. There are various traditional physicochemical techniques such as electro-remediation, immobilization, stabilization, and chemical reduction to clean the contaminants from the soil. However, these methods require high energy, trained manpower, and hazardous chemicals make these techniques costly and non-environment friendly. Bioremediation, which includes microorganism-based, plant-based, microorganism-plant associated, and other innovative methods, is employed to restore the contaminated soils. This review covers some new aspects and dimensions of bioremediation of heavy metal-polluted soils. The bioremediation potential of bacteria and fungi individually and in association with plants has been reviewed and critically examined. It is reported that microbes such as Pseudomonas spp., Bacillus spp., and Aspergillus spp., have high metal tolerance, and bioremediation potential up to 98% both individually and when associated with plants such as Trifolium repens, Helianthus annuus, and Vallisneria denseserrulata. The mechanism of microbe’s detoxification of metals depends upon various aspects which include the internal structure, cell surface properties of microorganisms, and the surrounding environmental conditions have been covered. Further, factors affecting the bioremediation efficiency and their possible solution, along with challenges and future prospects, are also discussed.

“…The contamination of soils with potentially toxic elements (PTEs) has become a global concern due to its harmful effects on soil biota and plant and human health (Karimi et al 2018;Khodaverdiloo et al 2020). Cadmium (Cd) is a highly toxic mobile PTE that is carcinogenic to all living organisms (Karimi et al 2018;Khodaverdiloo et al 2020). Anthropogenic activities, such as applying agrochemicals, smelting, mining, and irrigating wastewater irrigation, have accelerated Cd contamination in soils (Kamran et al 2019;Rajendran et al 2019).…”

The immobilization of soil cadmium (Cd) by biochar and modified biochar is an eco-friendly and cost-effective strategy. In the current study, the effect of raw biochar (BC) and iron-modified biochar (Fe-BC) derived from common reed on the fractionation and mobility of Cd was evaluated, as was its effect on soil microbial activity in contaminated calcareous soil. Treatments involved a combination of two factors: type of biochar (CK: Control, BC, and Fe-BC) and soil Cd concentration (0, 15, and 30 mg kg −1). Treatments were applied to the soil and incubated for 90 days. The application of both biochars increased soil pH and soil organic carbon content (16.6-48.0%), microbial biomass carbon (40.5-75.1%), basal respiration (16.6-48.0%), substrate-induced respiration (12.4-41.9), and dehydrogenase activity (25.5-102.1%), while it reduced diethylene-triamine pentaacetic acid (DTPA)extractable Cd (22.1-39.5%). The addition biochars, particularly Fe-BC, prominently decreased the concentration of exchangeable and carbonate fractions and increased the concentration of Fe-MnOx, as well as the organic and residual fractions of Cd in the soil. Moreover, relative to the control treatment, the incorporation of raw and Fe-modified biochar into 30 mg kg −1 Cd-spiked soil significantly decreased the Cd mobility factor (MF) value by 14.5 and 21.8%, respectively. Fe-modified biochar had a more significant impact than raw biochar on the immobilization of Cd in the soil, and its improved soil microbial activity to a greater extent. Overall, the findings indicate that Fe-modified biochar derived from common reed can immobilize Cd and improve soil microbial attributes in contaminated calcareous soil. Therefore, it can be used as an eco-friendly amendment for restoring Cdcontaminated calcareous soil.

“…Soil or land degradation resulting from salinity associated with HMs is a major environmental constraint, particularly in arid and semiarid provinces of the world (Shahid et al 2018;Khodaverdiloo et al 2020). Argentina, China, Central Asia, Egypt, India, Iraq, Mexico, Portugal, Mongolia, Pakistan, Russia, Spain, Sudan and USA are the major provinces that turn out to be "Global Soil Salinization Hotspot" where most of the cultivated lands are either salt affected or facing the degradation glitches due to excessive salt or metal concentration (Qadir et al 2014;Ivushkin et al 2019).…”

Assessment of phytoremediation capacity of three halophytes: Suaeda monoica, Tamarix indica and Cressa critica

et al. 2020

Halophyte is a distinctive group of plants that can survive, even well flourish, at a concentration of Na + and Cl − ions along with heavy metals that would be lethal to most of the agricultural crop species. These capabilities make certain halophytes good contenders for phytoremediation through phytoextraction or phytostabilization of the salt and heavy metals (HMs) in polluted soils. Thus, the present study elucidates the phytoextraction capacity of three halophytes (Suaeda monoica, Tamarix indica and Cressa critica) growing in saline soil (EC 112 ds m −1), with higher level of HMs rather than a cultivated soil. The accumulation of ions in above-ground tissue was determined in the all three studied plants, considering the fact that maintaining a stable cytosolic Na + /K + ratio has become a crucial salinity tolerance mechanism. The higher salinity of soil resulted in high level of Na + ions in leaves, increased synthesis of osmolyte components and robust antioxidant activities to combat the oxidative stress. As whole, changes in cellular metabolites were determined by using FT-IR spectroscopy, evident as differential FT-IR profiles in both leaves and stem specific to these metabolites. The considerable amounts of HMs accumulation including Zn, Fe, Mn, Cu, Cr, and Cd with highest being Fe in above-ground tissue of all three studied halophytes were obtained. These preliminary findings represent S. monoica, T. indica and C. cretica as potent phytoremediation plant using phytosequestration to accumulate HMs. The present study project a light on the use of these three plants in reclamation of degraded saline soils.
