Phytoremediation is an economically viable green technology that utilizes hyperaccumulator plants to remove heavy metals (HM) from the soil. Hyperaccumulators are adept at sequestering high concentrations of HM in aerial parts and intracellular detoxification through cell wall binding, organic acids, chelation sequestration. Excess activate oxidative stress defense mechanisms initiate synthesis stress-related proteins plants. Plethora studies have assessed feasibility phytoextraction demonstrated biomass metal hyperaccumulation two basic requirements for making process efficient. However, biochemical pathways involved uptake, translocation sequestration these not fully understood. Thus, more fundamental understanding traits needed optimize phytoextraction. In this review, we aim focus on transport, accumulation common such as mercury (Hg), lead (Pb), cadmium (Cd), chromium (Cr), zinc (Zn), copper (Cu) Arsenic (As) We will also discuss prominent metallophytes their phytoremediation strategies. This study be helpful uptake by hyperaccumulators. It would assist gaining knowledge about adaptation strategy used achieve homeostasis.

Abstract Globally, substantial research into endophytic microbes is being conducted to increase agricultural and environmental sustainability. Endophytic such as bacteria, actinomycetes, fungi inhabit ubiquitously within the tissues of all plant species without causing any harm or disease. Endophytes form symbiotic relationships with diverse can regulate numerous host functions, including resistance abiotic biotic stresses, growth development, stimulating immune systems. Moreover, endophytes play a dominant role in nutrient cycling, biodegradation, bioremediation, are widely used many industries. have stronger predisposition for enhancing mineral metal solubility by cells through secretion organic acids low molecular weight metal-specific ligands (such siderophores) that alter soil pH boost binding activity. Finally, synthesize various bioactive compounds high competence promising candidates new drugs, antibiotics, medicines. Bioprospecting novel secondary metabolites has given momentum sustainable agriculture combating stresses. Biotechnological interventions aid played pivotal crop improvement mitigate stress conditions like drought, salinity, xenobiotic compounds, heavy metals. Identification putative genes from conferring tolerance diseases, apart those involved accumulation degradation contaminants, could open avenues development. Furthermore, detailed biochemical understanding endophyte entry colonization strategy would better help manipulating productivity under changing climatic conditions. Therefore, present review highlights current trends based on SCOPUS database, potential biotechnological microorganisms stresses influencing productivity, future opportunities improving tolerance, their contribution remediation hazardous contaminants.

The public and environmental health consequences of mercury (Hg) methylation have drawn much attention considerable research to Hg processes their dynamics in diverse environments under a multitude conditions. However, the net methylmercury (MeHg) concentration that accumulates environment is equally determined by rate MeHg degradation, complex process mediated variety biotic abiotic mechanisms, about which our knowledge limited. Here we review current on degradation its potential pathways mechanisms. We describe detoxification resistant microorganisms employ resistance (mer) system reductively break carbon–mercury (C–Hg) bond producing methane (CH4) inorganic mercuric Hg(II), then reduced reductase elemental Hg(0). Very recent has begun elucidate mechanism for long-recognized mer-independent oxidative demethylation, likely involving some strains anaerobic bacteria as well aerobic methane-oxidizing bacteria, i.e., methanotrophs. In addition, photochemical chemical demethylation are described, including roles dissolved organic matter (DOM) free radicals dark natural little currently known. focus mechanisms highlight uncertainties known effects factors leading degradation. Finally, suggest future directions further biochemical significance controlling production ecosystems.

Abstract The tremendous increase in human population and industrialization has exacerbated the existing problem of water pollution to a great extent. textile industry is major cause this due its significant use organic synthetic dyes as coloring materials during dyeing process. presence color wastewater environmental concern, these are resistant degradation by physio‐chemical treatments. Bioremediation an attractive method that can completely degrade while also being cost‐effective. This comprehensive review aims provide brief insight into bioremediation based on some latest emerging treatment technologies for removal dyes. Starting with importance decolorization their impacts, different analyzed special emphasis limitations. detailed biodegradation mechanisms using bacterial species (bacteria, fungal, algae, enzyme, mixed culture) under aerobic anaerobic conditions thoroughly discussed. In article, factors affecting implementation biological explained. addition, technologies, such nano‐bio materials, genetic engineering, phytoremediation, electro‐bioremediation (microbial electrochemistry technology, MET), integrated/hybrid (such processes processes, electro‐coagulation, adsorption, ultra‐filtration, membrane, advanced oxidation) critically reviewed; challenges future perspectives highlighted. © 2021 Society Chemical Industry (SCI).

Land that has little to no utility for agriculture or industry is considered marginal land. This kind of terrain frequently found on the edge deserts other arid regions. The amount land can be used continues constrained by increasing desertification, which being caused climate change and deterioration agriculturally areas. Plants associated microorganisms are remediate enhance soil quality They represent a low-cost usually long-term solution restoring fertility. Among various phytoremediation processes (viz., phytodegradation, phytoextraction, phytostabilization, phytovolatilization, phytofiltration, phytostimulation, phytodesalination), employment specific mechanism determined state soil, presence concentration contaminants, plant species involved. review focuses key economically important plants phytoremediation, as well challenges growth capability with emphasis advantages limits in soil. Plant growth-promoting bacteria (PGPB) boost development promote bioremediation secreting variety metabolites hormones, through nitrogen fixation, nutrients’ bioavailability mineral solubilization. also emphasizes role PGPB under different abiotic stresses, including heavy-metal-contaminated land, high salinity environments, organic contaminants. In our opinion, improved fertility lands using significant (e.g., Miscanthus ) dual precession technology will result reclamation general restoration native vegetation.

With the enormous increase in population and industrial network, harmful pollutants affecting biota have also escalated. The are consumed by living organisms directly or indirectly reducing animal economic wellbeing. degradation of contaminants is imperative owing to prolonged persistence like plastics, heavy metals, pesticides, dyes, pharmaceuticals, hydrocarbons. Remediation such requires efficient methods prevent mobilizing-contaminants leaching into soil finally human beings. In this regard, metagenomics (MGs), a non-culturable technique, involving direct recovery genetic material from environmental samples an effective tool for understanding remediation process mediated microorganisms their gene products enzymes. MGs offers gateway previously hidden microbial communities grown normal extreme environment through sequence-based function-based approaches. culture-independent approach combination with other meta-omics approaches involves easy rapid method selection remediation-efficient microbes. This paper elucidates negative implications several on terrestrial aquatic besides highlighting role associated characterizing contaminant degrading research related bioremediation can help generate information that will improve aid deciphering complete microbe-mediated mechanism pathways. future be helpful comprehensively understand mechanisms involved bioremediation, develop new strategies models application rapid, accurate optimize technique. Furthermore, determine diversity specific genes act as pollution biomarkers.
