“…(2011); Eliescu et al (2020); Huang et al (2009), este cambio propicio la disociación química tanto de grupos funcionales carboxílicos, amino, metilo, fosfato e hidróxidos constituyentes de la pared celular y de los metales en solución, aumentando su solubilidad y favoreciendo la disponibilidad de biosorción en la biomasa y la bioacumulación intracelular.…”

“…Al examinar el crecimiento miceliar de P. ostreatus en concentración de 50 mg L -1 de solución de Pb observaron que no fue inhibido, permaneciendo viable después de 20 días de exposición en medio sólido. Se puede suponer que P. ostreatus tiene una gran capacidad para tolerar y eliminar Pb; a través, de procesos consecutivos de adsorción y bioacumulación debido a que este metal puede fijarse en los grupos funcionales aminas (NH 2 ) e hidroxilos (OH) de la estructura química de la pared celular, logrando penetrar hasta la célula depositándose en el citosol de la estructura celular del micelio (Huang et al, 2009;Wang et al, 2019;Eliescu et al, 2020).…”

“…El mismo comportamiento lo registraron da Rocha Ferreira et al (2019) quienes midieron el incremento radial del micelio de P. ostreatus en el rango de (10-150 mg L -1 ) de Cr (VI) durante 10 días de incubación, sin inhibición de crecimiento, lo que implica que altas concentraciones de soluciones metálicas de Cr inhiben el crecimiento del hongo por el posible daño a la membrana celular, la inducción de la peroxidación lipídica, la formación de especies reactivas de oxígeno, así como daño a las estructuras de ADN y proteínas (Huang et al, 2009: Sazanova et al, 2015Eliescu et al, 2020).…”

A nivel mundial, el uso indiscriminado de productos metálicos vertidos en agua utilizada en la agricultura ha generado una grave contaminación, por lo tanto, es importante establecer una metodología para su descontaminación a través de procesos biológicos, con hongos basidiomicetos ya que se ha demostrado que pueden degradar una serie de contaminantes orgánicos persistentes utilizando enzimas extracelulares, además de eliminar metales disueltos del agua mediante biosorción, actuando, como un intercambiador natural. Los objetivos de este trabajo fueron determinar entre tres metales (Pb, Cr y Cd) cuál fue removido más eficientemente de la solución acuosa por el micelio del hongo Pleurotus ostreatus, así como evaluar su tolerancia y describir los efectos causados por cada uno sobre su estructura celular. La adsorción de metales por el micelio en medio líquido se evaluó utilizando medio Kirk modificado, se cuantificaron las concentraciones retenidas durante 8 días en solución de 20 mg L-1 de cada elemento, los resultados indicaron que la adsorción de Pb (75%) fue la más eficiente, seguida de Cr (42%) y Cd (2.25%). En los resultados en medio de cultivo sólido (PDA) ninguna concentración de Pb y Cr inhibió el crecimiento del micelio, sin embargo, con Cd se inhibió a partir de 60 mg L-1; no obstante, los tres elementos causaron en el micelio alteraciones a nivel estructural. En conclusión, la cepa de P. ostreatus presento tolerancia y biosorción significativa (p≤ 0.05) para

“…For the biosorption of lead (II) from aqueous solution, Eliescu et al [81] compared the biosorbent activity of Pleurotus ostreatus biomass derived from spent mushroom substrate and observed Pb(II) sorption parameters. The Pleurotus ostreatus spent substrate (POBM) had a higher adsorption potential (85.91 mg g −1 ) than that of the Pleurotus ostreatus original spores (PO) (57.73mg g −1 ).…”

Currently, the food and agricultural sectors are concerned about environmental problems caused by raw material waste, and they are looking for strategies to reduce the growing amount of waste disposal. Now, approaches are being explored that could increment and provide value-added products from agricultural waste to contribute to the circular economy and environmental protection. Edible mushrooms have been globally appreciated for their medicinal properties and nutritional value, but during the mushroom production process nearly one-fifth of the mushroom gets wasted. Therefore, improper disposal of mushrooms and untreated residues can cause fungal disease. The residues of edible mushrooms, being rich in sterols, vitamin D2, amino acids, and polysaccharides, among others, makes it underutilized waste. Most of the published literature has primarily focused on the isolation of bioactive components of these edible mushrooms; however, utilization of waste or edible mushrooms themselves, for the production of value-added products, has remained an overlooked area. Waste of edible mushrooms also represents a disposal problem, but they are a rich source of important compounds, owing to their nutritional and functional properties. Researchers have started exploiting edible mushroom by-products/waste for value-added goods with applications in diverse fields. Bioactive compounds obtained from edible mushrooms are being used in media production and skincare formulations. Furthermore, diverse applications from edible mushrooms are also being explored, including the synthesis of biosorbent, biochar, edible films/coating, probiotics, nanoparticles and cosmetic products. The primary intent of this review is to summarize the information related to edible mushrooms and their valorization in developing value-added products with industrial applications.

In this research, biosorption of Lead using spent Gelidiella acerosa from synthetic aqueous phase was studied in batch and fixed bed modes. Biosorbent was prepared from waste biomass of Gelidiella acerosa after extraction of agar as a model industrial waste recycle. The process efficiency and optimum lead uptake were evaluated by considering initial pH, lead concentration, and biosorbent dosage as process variables and contact time and temperature as fixed parameters. Central composite design of Response Surface Methodology was used to optimize process parameters and ANOVA showed that initial pH of lead solution significantly influences the biosorption.Interaction effects of different process parameters on process efficiency were analyzed with the help of surface response plots. The highest lead biosorption of 90.75% was noticed at optimum conditions of pH 5.15, initial lead concentration 27.35 mg L −1 and biosorbent dosage 0.04 g. Various kinetic equations were used to analyze the biosorption mechanism and found that metal binding is due to chemical reaction with multi stage mass transfer. Langmuir isotherm was found to be well fitted to equilibrium data.Column studies were also conducted to assess the suitability of the process to continuous operations. The most popular Thomas and Yoon nelson models were used to evaluate the fitness of column studies. Biosorbent was characterized using FTIR and SEM to determine surface functional groups and surface texture.
