“…Nickel (3.78 mg/Kg) was also present in minor concentration. This slight variation in the metal contents might be caused by a number of physical factors, such as temperature, sampling site and various other environmental factors as reported by(Bedi et al 2018).…”

“…Similarly, showing absorption band around ~ 537 cm − 1 due to Fe-O stretching. The observed functional groups showed that proteins in the fungal metabolites form a capping layer on nanoparticles in order to prevent them from agglomeration and therefore stabilizing them in solution (Bedi et al 2018).…”

“…Recently, this method has been used to treat industrial and municipal wastes, as well as to recover important metals from low-grade ores and concentrates. Myconanomining is considered as a safe and eco-friendly technique for the conversion of metal based bulk material into nanoparticle form (Bedi et al 2018). There are many reports in which fungi are being used as agents for bioleaching to dissolve valuable metals from the tailing waste (Biswas et al 2013;Madrigal-Arias et al 2015).…”

“…Heterogeneity was also observed when data was compared with other investigators asIlyas et al (2013) reported the composition of mine tailing as Fe (18375 mg/Kg), Ni (42 mg/Kg), Zn (25.5 mg/Kg), Cu (20.1 mg/Kg), Mg (20 mg/Kg) and Co (15.3 mg/Kg) respectively. Similarly,Bedi et al (2018) investigated the chemical composition of iron ore tailing and reported that iron (41,191 mg/Kg) was the most abundant metal found in ore tailing followed by aluminum (34,530 mg/Kg), silica(12,316 mg/Kg), manganese (9614 mg/Kg) and zinc (435 mg/Kg). Nickel (3.78 mg/Kg) was also present in minor concentration.…”

Ore Tailing, a rich source of minerals stimulates the researchers to microbially recover valuable metals from this toxic waste to usable for in an eco-friendly manner. In current research, A. niger metabolites exhibited good potential for metal ions solubilization and further conversion into nano formulation by protein end capping. Synthesis of biorecovered nanoparticles were confirmed by systematic characterization using AAS, UV/VIS, FTIR, SEM and Zetasizer analysis. These BNPs with various concentrations (0.2, 0.4, 0.6, 0.8 and 1.00 ppm) were evaluated for their efficacy on seed germination and seedling growth of wheat (Triticum aestivum L.) by seed priming technique. Seedlings displayed pronounced seed germination (100% ± 0.00) and seedling growth in terms of root and shoot length (8.31 ± 0.18 &7.46 ± 0.15) in the seeds treated with 1.00 ppm of BNPs followed by green synthesized Fe NPs and bulk Fe with germination % (99.64 ± 0.12 & 99.25 ± 0.13) and root and shoot length (7.42 & 6.48cm & 6.62 & 6.26cm) respectively. Minimum growth was observed in water as control representing germination % (96.48 ± 0.13) and seedling growth (4.36 & 4.81 cm). BNP has stimulatory effect on wheat seeds as progressive increase in their germination and physical parameters were observed. So, biosynthesized nanoparticles could be an initiative for the development of nano-biofertilizers of potential importance in agriculture sector.

“…Los problemas ambientales causados por la explotación minera han aumentado significativamente por la liberación de diversos elementos químicos en el entorno circundante (aire, agua y suelo) (Navarro et al 2008, Varrica et al 2014, Zeng et al 2018. Asimismo, estas actividades minero-metalúrgicas generan cantidades considerables de residuos denominados jales, que contienen metales como sulfuros (Ye et al 2017) y fluidos o lodos de procesamiento (Kossoff et al 2014), los cuales son restos de grano fino que se depositan sin tratamiento en presas de jales (Entezari-Zarandi et al 2017, Bedi et al 2018. Los sulfuros se oxidan en contacto con el agua, lo que reduce el pH circundante y produce lixiviación de los óxidos (Kiventera et al 2018).…”

La mina Cerro de Mercado, ubicada en el estado de Durango, México, ha almacenado jales durante el proceso de extracción de hematita y magnetita durante aproximadamente 80 años. La presente investigación tuvo como objetivo llevar caracterizar los jales de la presa Boleo Estrella de la mina Cerro de Mercado y determinar el potencial de generación de drenaje ácido, considerando la Norma Oficial Mexicana NOM-141-SEMARNAT-2003. El muestreo se realizó de acuerdo con la Norma Mexicana NMX-AA-132-SCFI-2006 y se obtuvieron 27 muestras en 16.2 ha de la superficie de la presa. Como resultado de la caracterización de dichos residuos, se obtuvieron valores de pH alcalinos y concentraciones mínimas de azufre y sulfatos; la relación potencial de neutralización/potencial de acidez fue mayor a 1.2, lo que indica que no son generadores potenciales de drenaje ácido. Por otro lado, la determinación de metales y metaloides considerados elementos potencialmente tóxicos presentes en las muestras de jales, evidencian la presencia de arsénico (As) y bario (Ba) en valores inferiores a los límites máximos permisibles (LMP) indicados en la NOM-157 SEMARNAT-2009; asimismo, el 22.2 % de dichas muestras está dentro de los LMP establecidos para cromo (Cr) y el 77.8 % se halla ligeramente por encima de los LMP. En el 66.7 % de los jales muestreados no se detectó antimonio (Sb); sin embargo, el 33.3 % restante contiene Sb en cantidades superiores a los LMP. De acuerdo con el estudio realizado, se puede deducir que los jales analizados no generan drenaje ácido y en las condiciones ambientales actuales, aun con la presencia de Cr y Sb, no presentan peligro para el ambiente.

Green Nanoparticles: The Future of Nanobiotechnology

Fungi are multicellular, eukaryotic life forms that lack chlorophyll and play a major role in nutrient and carbon cycling in the biosphere as pathogens, mutualistic symbionts, and opportunistic heterotrophs. Fungi are also considered as attractive agents for the biosynthesis of nanoparticles, both intracellularly as well as extracellularly. Myconanotechnology is an upcoming science and technology innovation where fungi are explored for the green synthesis of nanomaterials. As compared to bacteria, the use of fungus is more advantageous since they provide good biomass and easy recovery and have fewer requirements of additional steps to extract the filtrate. Compared to other prokaryotic entities and even plants, the fungal mycelium has proven to be quite sturdy in withstanding adverse conditions during culturing in bioreactors or other chambers during the nanofabrication process. The chapter discusses the role of filamentous fungi, yeast, mushrooms, and lichens in the green synthesis of nanoparticles.
