Heavy metals are found in nature trace amounts but, due to rapid industrialization, urbanization and various anthropogenic activities, their concentration the environment has reached an undesired level recent years. Pollution by heavy become a serious threat human health toxicity long-term persistence environment. The use of microorganisms detoxifying great potential tackling these adverse effects. Microbial bioremediation is economical effective technique alleviate toxic forms converting them into less forms. Upon inoculation, microbes help reduce elevated concentrations both soil plants. exposure some high made resistant acquire ability remove different using types mechanisms. processing conditions that affect microbial remediation include temperature, pH, substrates. Recent technological advances have suggested it be better alternative other approaches. study such interaction crucial understanding developing strategies for future research directions.

Arsenic is a toxic metalloid naturally found in the earth's crust and released into environment through natural anthropogenic activities.Arsenic becomes exceptionally even at low exposure levels because of its high water solubility bioaccumulation tendency different environmental matrices.Crops receiving arsenic contaminated irrigation accumulate it degrees depending on species variety.Consumption crops drinking has been identified as important routes for transfer food chain.Besides, consuming seafood livestock-based products such meat milk from endemic regions also contributes to chain contamination.The literature clearly indicates that effect any product highly dependent chemical speciation.Inorganic compounds are generally more than organic forms.On consumption water, only bioavailable form goes directly human body interferes with metabolic pathways.Thus, prolonged toxicity leads carcinogenic non-carcinogenic health risks arsenicosis, cancers, hepatotoxicity, kidney failure, skin diseases.Therefore, this review highlights distribution mobility soil-plant system, bioavailability plant products, chain, risks.In current state when emerged worldwide threat, an integrated strategy urgently required combat contamination, mandating creation national international action strategies contamination mitigation.

Abstract Mercury (Hg), arsenic (As), cadmium (Cd), lead (Pb) and other toxic heavy metals (HM) pose significant risks to the environment, negatively impacting morpho-physiological biological traits of plants. At present, elements constitute a proportion food chain, exerting an impact on human health due their mobility biomagnification. The metal exclusion technique stands out for its robust performance, even when dealing with extremely low concentrations. Its eco-friendly nature cost-effectiveness further enhance value. Due exponential growth pattern bacteria, these exhibit high persistence are recommended processes. Moreover, vacuoles like vesicles present in mycorrhizal fungi can hold levels HM. Microbe-assisted phytoremediation primarily occurs through two mechanisms: direct provision essential nutrients phytohormones, such as plant regulators, siderophores, enzymes, mineral; or indirectly by modulating detoxification process. This indirect mechanism involves microbes aiding accumulation sequestration plants secretion specific extracellular substances organic acids, biosurfactants, chelators. bioavailability translocation rhizosphere also altered via various mechanisms acidification, precipitation, complexation redox reactions. understanding molecular physiological processes underpinning functions arbuscular (AMF) reducing HM toxicity, improving performance procuring under HM-toxicity has significantly improved recent years. In this review, adaptive persistent methods related cross-protective bacteria (MF) resulting from evolutionary consequences toxicity have been addressed. Furthermore, article offers details reactions host fungi, stress, which may be useful unveiling new knowledge about strategies HMs remediation.

Anthropogenic activities have a critical influence on climate change that directly or indirectly impacts plant and microbial diversity our planet. Due to change, there is an increase in the intensity frequency of extreme environmental events such as temperature rise, drought, precipitation. The greenhouse gas emissions CO 2 , CH 4 NOx, water vapor, global temperature, rainfall patterns impacted soil–plant-microbe interactions, which poses serious threat food security.

(wheat) growth, photosynthetic pigments, oxidative stress parameters, roots’ lignin content, Cd ions accumulation plants were analyzed. results showed tested Cd-tolerant BS improved ability wheat seeds to germinate presence different concentrations (0, 0.1, 0.5, 1 mM). In addition, bacterial significantly decreased damaging (1 mM) seedlings’ linear dimensions (lengths roots shoots), biomass, as well integrity permeability cell walls (i.e., lipid peroxidation electrolyte leakage) resulted reduced H2O2 generation. pretreatment prevented Cd-induced degradation leaf pigments chlorophyll (Chl) a, Chl b, carotenoids. Moreover, intensified deposition under normal and, especially, conditions, thereby enhancing barrier properties wall.
