“…In response to toxic particles in the environment, microorganisms activate a defense mechanism triggering precipitation. Interaction between functional groups on the biosorbent's cell wall and particles leads to precipitate formation 19 , 61 . Physical adsorption occurs on the biosorbent's surface, particularly involving cell walls in microorganisms, through interactions like van der Waals forces, with the extent of physical adsorption influenced by the biosorbent's surface area 63 .…”

“…Generally, several physicochemical (membrane processes, electrocoagulation, ionic exchange, coagulation-flocculation, precipitation, etc.) and biological methods (biodegradation and biosorption) are suggested to remove pollutants in wastewater treatment 19 . Biological treatments have gained huge attention among all these treatment methods due to their sustainability and low-cost 20 .…”

Nanotechnology has increased the release of nanoparticles into the environment, which poses a risk to human health and the ecosystem. Therefore, finding ways to eliminate these hazardous particles from the environment is crucial. This research studied the ability of Trametes versicolor fungi to remove carboxylated multi-walled carbon nanotubes. The study analyzed the impact of pH, MWCNT-COOH concentration, and initial fungal growth time on the removal process. The properties of the adsorbent were measured before and after the biosorption process using SEM, FTIR, and EDS techniques. The results showed that the live biomass of T. versicolor was more effective in removing nanoparticles than dead biomass at 30 °C and pH 7. An increase in carbon nanotube concentration from 5 to 20 mg. mL−1 decreased biosorption potential from 100% to 28.55 ± 1.7%. The study also found that an increase in initial fungal growth time led to higher biomass production and adsorption capacity, increasing biosorption ability for concentrations > 5mg. ml−1. The biosorption kinetics followed a pseudo-second-order model and corresponded most closely to the Freundlich isotherm model. The adsorption capacity of live fungal biomass to remove multi-walled carbon nanotubes was 945.17 mg. g−1, indicating that T. versicolor fungi have significant potential for removing carbon nanostructures from the environment.

“…Diverse physical and chemical processes for dyes removal from wastewaters exist. Among the physical methods are adsorption, flocculation, coagulation, and membrane filtration [8,[17][18][19]. Chemical methodologies are mainly based on the oxidation with hydrogen peroxide, Fenton's reaction, photocatalysis, electrochemistry, and ozone [20][21][22][23].…”

Synthetic dyes are highly stable, offer a wide range of colors, and have easy industrial applications. Nevertheless, dyes become a problem in aqueous environments due to their long permanence and low biodegradability. White-rot fungi are useful to degrade dyes through their ligninolytic enzymes and/or biosorption. This work evaluated the effect of 2,5-dimethylaniline, glucose, ammonium tartrate, copper sulfate, pH, and temperature on the degradation of Turquoise Blue (TB) dye in aqueous solutions by Leptosphaerulina sp. (Colombian native fungus). Assays were developed applying a response surface experimental design, which found that the ammonium tartrate and pH are the most influential variables on TB removal. Leptosphaerulina sp. decolorizes aqueous solutions with TB (99%, at day 8), mainly through sorption (89%). Therefore, one of the significant findings from this study is that the Leptosphaerulina sp. biomass is a promising alternative as biosorbent, in comparison to physical-chemical traditional methods, for treating wastewaters polluted with dyes
