Abstract This study aimed to assess the diversity of endophytic fungi isolated from Abutilon indicum using morphological and molecular techniques. The isolates were exposed various levels salinity, temperatures, heavy metals, including Ag 2+ Zn , at concentrations 3.6 11.5 mM. Thirty root segments each plant cultured on potato dextrose agar plates. Four randomly infected segments, belonging genera Aspergillus, Meyerozyma, Penicillium. phylogenetic analysis revealed significant among Aspergillus welwitschiae, indologenus, Meyerozyma carpophila, Penicillium citrinum with a 99% similarity in their sequences. Most able thrive under salt stress conditions NaCl 200 mM (26%), 400 (24%), 600 (21%), 800 (13%), 1000 (16%). Tolerant temperature, endophytes could survive range 25 °C 35 but not above 50 °C. Heavy metals tolerance 89% these led decrease biomass production when . Endophytic fungal showed decreased sensitivity between 33% 60% strong growth high These findings that A. welwitschiae enhanced conditions. Our indicate presence different leads growth, this be useful for phytoremediation purposes.

Heavy metals represent a significant contributor to water pollution, posing serious environmental and health risks due human activities industrialization. The release of heavy metal contaminants into sources has spurred extensive research wastewater treatment methods, including precipitation, evaporation, ion exchange, membrane processes, electroplating. However, these conventional techniques often prove costly, limited in effectiveness, may inadvertently exacerbate pollution concerns. This review underscores biosorption as highly promising alternative for effectively removing harmful ions from sources. Biosorption, physical technique, capitalizes on mechanisms such surface complexation, leveraging more economical biological materials biosorbents. Microorganisms, encompassing bacteria, fungi, algae, plant products, emerge pivotal agents biosorption, offering sustainable cost-effective approach. There is growing interest harnessing local microbiota aiming mitigate contamination without adverse impacts. Notably, both living deceased fungal biomass have garnered attention adsorbents eliminating solutions. behavior presents numerous advantages, warranting further fully exploit its potential endeavors.

Abstract In present study, 15 morphologically different fungi isolated from rhizopheric soils of an industrial area were screened for their Zn 2+ removal efficiency aqueous solution. Isolate depicting highest potential was molecularly identified as Aspergillus terreus SJP02. Effect various process parameters viz. biosorbent dose, contact time, temperature, agitation rate, pH and initial concentration on the fungal sorption capacity studied. The exhibited maximum 10.7 ± 0.2 mg g − 1 in 60 min. Desorption studies showed 71.46% recovery rate 120 min with 0.01 N HNO 3 , indicating efficient metal reuse subsequent reutilization spent mycosorbents. Acid digestion study suggested adsorption being primary mechanism accounting 87% removal. It further confirmed by FE-SEM EDX analysis.

Abstract Micropollutants, such as heavy metals and pesticides, inhibit microbial growth, threatening ecosystems. Yet, the mechanism behind mycoremediation of pesticide lindane multiple (Cd, Total Cr, Cu, Ni, Pb, Zn) remains poorly understood. In our study, we investigated cellular responses in Aspergillus fumigatus PD-18 using LC-MS/MS, identifying 2190 proteins, 1147 which were consistently present under both stress conditions. Specifically, Cu-Zn superoxide dismutase heat shock proteins up-regulated to counter oxidative protein misfolding. Proteins involved intracellular trafficking, secretion, vesicular transport; RNA processing modification showed enhanced abundance regulating response pathways. Additionally, haloalkane dehalogenase homogentisate 1,2-dioxygenase played pivotal roles mineralization. Bioinformatics analysis highlighted enriched pathways Glyoxylate dicarboxylate metabolism Purine metabolism, that are crucial for combating adverse environments. We identified hub 26 S proteasome regulatory subunit complex potential biomarker remedial targets wastewater, suggesting practical applications environmental remediation.

The expanding population, rapid growth in urbanization, and industry exacerbate pollution-related issues. Pollution of the soil water has an impact on both human health environment. Thus, restoration cleanup contaminated areas represent important technological environmental challenge for sustainable development. Among various techniques used to remediate contaminants, Mycoremediation, use fungi or its derivatives, is by far most widely employed remove degrade metal metals, persistent organic pollutants, some emerging pollutants. This chapter summarizes key aspects mycoremediation as eco-friendly, economical, approach remediation terrestrial aquatic ecosystems. current discusses potential degrading contaminants such heavy agricultural pharmaceutical wastes, dyes, polycyclic aromatic hydrocarbons. Likewise, we address major fungal species, their mechanisms, applications mycoremediation. Afterward, economic benefits, problems, future improving efficiency are addressed.

Tannery effluent poses significant risks to soil health, primarily through contamination with heavy metals like chromium, sulphides, and persistent organic pollutants (POPs). These toxic substances inhibit microbial activity, reducing nutrient cycling matter decomposition essential for fertility. Beneficial microorganisms, including nitrogen-fixing bacteria, are particularly affected, leading altered communities dominated by less advantageous, metal-tolerant species. Accumulation of POPs disrupts enzymatic activities, interferes plant root growth, complicates remediation efforts due pollutant migration groundwater potential entry into the food chain. Prolonged exposure such contaminants diminishes fertility, reduces resilience, ecosystem services, posing threats agricultural productivity environmental health. This review was aimed outline what made bioremediation a superior treatment technology among other methods used in remediating tannery contaminated soil. Efforts mitigate impacts involve combination physical, chemical, biological technologies. Physical washing, flushing, thermal desorption focus on removing or isolating contaminants, while chemical approaches as oxidation, reduction, stabilization transform harmful forms immobilize them. Biological leverages microorganisms plants detoxify sustainably. Bioremediation strategies aid bioaugmentation biostimulation do enhance activity address inorganic effectively more than physical methods. Another excellent called phytoremediation can also effectively, Achieving better technique should be coupled stringent industrial regulations, sustainable tanning methods, stakeholder awareness

Yeasts have been extensively recognized as a type of model microorganism due to their facile cultivation, short growth cycle, and genetic stability. Different yeast strains, such Saccharomyces cerevisiae Rhodotorula mucilaginosa, exhibited notable sorption capacities for heavy metals metalloids. Yeast employs diverse pathways detoxifying via its cell walls, intracellular organelles, extracellular polymeric substances (EPSs). The wall has many functional groups adsorb metals, decreasing concentrations in the environment. In regions, some proteins are capable transporting into biological metabolic processes detoxification. electrostatic well complexation mechanisms between protein EPSs is accepted. Meanwhile, mannose glucose within target sugars with metals. Many yeasts can hence work excellent biomaterials bioremediation metal pollution. they be combined other materials enhance remediation efficiency. This study reviews underlying cases yeast-mediated detoxification, alongside highlighting yeasts’ industrial applications materials.
