Abstract Mercury (Hg) pollution of soil and water environments is a major global threat to human health, agri‐food systems ecosystems industrial activities mainly coal combustion augmented their content in different environmental media. Bioremediation nature‐based solution involving microbial‐ plant‐based (phytoremediation) technologies that clean‐up Hg contaminated sites. Here, we review Hg‐resistant bacteria how latest insights our understanding the cellular biochemical mechanisms mer operon genes responsible for resistance transformation have facilitated developments microbial Hg‐bioremediation. We also phytoremediation mechanisms, including those bacterial‐ fungi‐assisted processes, which shown promising results reducing 2+ 0 . This provides detailed knowledge novel bioremediation methods. Consequently, phyto‐based critical role reclamation Hg‐contaminated protection health ecosystems.

Published: Nov. 19, 2024

The increased presence of cadmium in the environment can lead to its increase food chain, particularly due accumulation consumable parts plants. For humans, ingesting containing high levels Cd is a significant exposure pathway. Being non-essential and non-metabolized element, it harmful microorganisms, animals, plants, even minimal concentrations. As result, there need for remediation both natural urban environments. Bioremediation sustainable eco-friendly technique cleaning up reducing contamination living organisms. This review explores potential phytoremediation, bioremediation approach that utilizes plants as agents decontamination, method restore such areas. Certain macrophytes, are capable remediating Cd. In response induced stress, activate various tolerance mechanisms, including antioxidant enzyme systems (as peroxidase, catalase, ascorbate superoxide dismutase, glutathione peroxidase) well non-enzymatic pathways (like phytochelatins). However, thorough understanding these mechanisms essential optimizing this method, especially application aquatic study will, therefore, existing detoxification Cd, along with strategies. highly correlated three main areas required sustainability: economic, environmental social.

Extraction Potential of Lolium perenne L. (Perennial Rye Grass) for Metals in Landfill Soil: Its Tolerance and Defense Strategies

Minerals, Journal Year: 2023, Volume and Issue: 13(7), P. 873 - 873

Published: June 28, 2023

Landfill sites open and close frequently throughout the world, taking over a significant amount of land leaving it contaminated unavailable to surrounding population for use. Different forms remediation methods have been employed rehabilitate state that poses less threat environment. Phytoremediation is one techniques has proven be effective, economical easier implement compared other methods. The main aim this study was explore potential use Lolium perenne L. remediate restore metal-contaminated landfill soil determine its stress tolerance mechanism(s). metal uptake, determined using inductively coupled plasma-optical emission spectroscopy (ICP-OES) plasma-mass (ICP-MS), revealed accumulate higher metals in roots than leaves, which further confirmed by translocation factor (TF) values all were below 1, ranging between 0.2 0.8, while Cu, Cr Pb had bioaccumulation (BCF) > 1. This confirms capable absorbing into root matrix but might restrict movement parts plant as defense mechanism against toxicity. In response metal-induced stress, displayed an increase enzyme activity superoxide dismutase, glutathione S-transferase, peroxidase amylases plants grown soil.

Published: March 13, 2024

Accumulation and concentration of contaminants in the soil have long been a byproduct industrialisation urbanisation, which has become primary environmental concern. Mitigation pollutants using chemical procedures their long-term application originated detrimental impact on all ecosystems. The green technologies such as bioremediation to solve risk factors contributes preservation fauna flora, ensuring at same time human health well-being. Bioremediation refers naturally occurring or any introduced microorganisms that break down sequestrate clean from pollutants. This review discusses different mechanisms mycorrhizae related habitats affecting functions removing itself. remediate either by phytoremediation (arbuscular mycorrhizal fungi [AMF]) degradation (ectomycorrhizae ericoid mycorrhizae). AMF are involved remediating non-degradable (heavy metals metalloids), while ectomycorrhizae preferred polar non-polar organic enzymes. efficiency depends mainly species involved, host plant species, type dose contaminants, methods used bioremediation, soil, conditions. Combining with advanced like metagenomics, metatranscriptomics, metabolomics accelerates remediation processes neutralise toxicity generated through present future anthropogenic activities.

Phytoremediation is a promising technique for reducing mercury (Hg) pollution. Little known about the phytoremediation potential of ramie (Boehmeria nivea L. Gaud.) and response its rhizosphere soil microbiome to Hg contamination. In this study, we planted in three plots contaminated with different levels pollution evaluated accumulation translocation. We also analyzed abundance, composition, predominant taxa bacterial community. Results showed that average THg concentration decreased by 30.80%, 18.36%, 16.31% L, M, H, respectively. Ramie displayed strong tolerance good performance, especially low level Hg. After planting, SOM CEC increased while pH, Eh, content soil. Proteobacteria, Actinobacteriota, Gemmatimonadota, Latescibacterota, NB1-j were identified as Hg-tolerant at phylum level, their abundance highly Hg-contaminated Redundancy correlation analyses indicated community structure was significantly correlated content.
