“…The exposure of the HM to plant may affect plants negatively which leads to lower siderophores production. On the other hand, microbial siderophores help in alleviating the stress for plant [77,78]. Numerous microbial species have been found producing siderophores and combating the metal stress in the plants [79].…”

Heavy metals (HMs) pollute the environment on a global scale and have different harmful effect on ecosystem. Outstripping accumulation of diverse toxic HMs in soils has altered the diversity, structure and function of microflora, degraded soils, reduces growth and yield of plant, and entered the food chain. HM treatment is necessary for maintaining the agricultural soil health. Many procedures and approaches have been used to recover contaminated soils in recent time, however, most of them were too pricey not environmentally friendly, and negatively affected soil properties. Usage of microbes was found as cost affective and ecofriendly approach for bioremediation of HMs. Microbes increased sustainability in agriculture soil health, which is essential to uninterrupted plant growth or improvement in stress full condition through mechanism likes productions phytohormones, organic acids, biosurfactants, exopolymers, antioxidant enzymes; and solubilization of phosphorus. It is well known that plant growth-promoting microbes enhance crop productivity and plant resistance to HM stress. In this following review, deep insight have has provided on mechanism of alleviation of HM stress by microbes and enhancement of plant growth promotion.

“…Currently, an active search for technologies of bioremediation of contaminated soils and water is in progress. The fungal degradation or transformation of hazardous organic compounds is called mycoremediation [2][3][4][5][6]. This simple and relatively inexpensive biotechnology could be applied to the remediation of soil and water polluted by industrial and agricultural waste, oil, and its byproducts, and a wide range of xenobiotics) [2][3][4][5][6].…”

“…Ligninolytic fungi are an eco-physiological group of wood-and soil-inhabiting basidioand ascomycetes, which are uniquely able to depolymerize and mineralize lignin in nature. The following properties make these fungi attractive for use in mycoremediation: (1) the ability to decompose and mineralize a wide range of persistent aromatic compounds that are structurally similar to the compounds formed during biosynthesis or biodegradation of lignin; (2) the wide distribution in nature; (3) the ability to grow on cheap natural substrates which can easily be introduced to polluted soil; (4) growth in the form of hyphae, allowing them to reach pollutants that are inaccessible to bacteria; (5) the production of a powerful extracellular nonspecific oxidative enzyme system; (6) the presence of lowmolecular-weight mediators that may increase the susceptibility of pollutants to enzymatic attack; (7) the production of constitutive forms of ligninolytic enzymes regardless of the presence of pollutants, which prevent the adaptation of the organism to contamination conditions [1,2,7].…”

Widespread Ability of Ligninolytic Fungi to Degrade Hazardous Organic Pollutants as the Basis for the Self-Purification Ability of Natural Ecosystems and for Mycoremediation Technologies

The ability of sixteen wood- and soil-inhabiting basidiomycete strains and four ascomycete strains to degrade the most hazardous, widespread, and persistent pollutants (polycyclic aromatic hydrocarbons, oxyethylated nonylphenol, alkylphenol, anthraquinone-type synthetic dyes, and oil) was found. The disappearance of the pollutants, their main metabolites, and some adaptive properties (activities of ligninolytic enzymes, the production of emulsifying compounds and exopolysaccharides) were evaluated. The toxicity of polycyclic aromatic hydrocarbons decreased during degradation. New data were obtained regarding (1) the dependence of the completeness of polycyclic aromatic hydrocarbon degradation on the composition of the ligninolytic enzyme complex; (2) the degradation of neonol AF9-12 by higher fungi (different accessibilities of the oxyethyl chain and the aromatic ring of the molecules to different fungal genera); and (3) the production of an emulsifying agent in response to the presence in the cultivation medium of hydrophobic pollutants as the common property of wood- and soil-inhabiting basidiomycetes and ascomycetes. Promise for use in mycoremediation was shown in the wood-inhabiting basidiomycetes Pleurotus ostreatus f. Florida, Schizophyllum commune, Trametes versicolor MUT 3403, and Trametes versicolor DSM11372; the litter-decomposing basidiomycete Stropharia rugosoannulata; and the ascomycete Cladosporium herbarum. These fungi degrade a wide range of pollutants without accumulation of toxic metabolites and produce ligninolytic enzymes and emulsifying compounds.

“…Therefore, besides limiting waste generation, the present scenario requires an efficient, feasible, and environmental-friendly approach for its management. Bioremediation is well recognized and widely accepted alternative to clean environment without harming the nature [1]. Further, it can be used under in-situ conditions with cost-effectiveness as the cost of excavation, transportation, treatment, etc is reduced due to its on-site application.…”

gricultural practices, industrial manufacturing, and lifestyle of human beings have raised the accumulation of hazardous compounds into the surrounding. It has drastically increased health issues and environmental concerns. Therefore, there is an urgent need for eco-friendly approaches to solving these multiple issues at a time. Contrary to the harmful chemical methods, bioremediation has emerged as an eco-friendly substitute for sustainable development. Bioremediation utilizes living microbiomes for cleaning environment and their sustainability. As advancement in science and technology, researchers have developed various bioremediation techniques but because of nature and type of pollutant, there is no single 'silver bullet' which can be applied to restore the polluted environment. The ever-increasing population and our reckless acts are turning the Earth into a huge garbage dump. The indiscriminate exploitation of resources making this condition worsen. Moreover, it is a major cause of climatic irregularities, environmental destructions, biodiversity shrinking, disease outbreaks, and agricultural issues. The present waste management efforts are proving insufficient to handle this situation.
