“…The spectra were deconvoluted with two peaks, 399.8 eV (−NH 2 /–NH−) and 401.6 eV (−NH 3+ /–NH 2+ −). 47 After CR adsorption, the content of −NH 2 or −NH– increased from 82.45 to 87.39%, which was due to the addition of the −NH 2 of CR. The C 1s spectra of mycelial pellet before and after CR adsorption are presented in Figure 5 e,f.…”

In the current study, Aspergillus fumigatus and Pseudomonas putida were co-cultured to obtain self-immobilized mycelial pellets to evaluate the decolorization efficiency of Congo red (CR). The obtained co-culture exhibited the highest decolorization efficiency of 99.22% compared to monoculture of A. fumigatus (89.20%) and P. putida (55.04%). The morphology and surface properties of the mycelial pellets were characterized by SEM, FTIR, BET, and XPS. The adsorption kinetics and isotherms were well described by pseudo-second-order and Langmuir models. The findings revealed that the removal efficiency of the mycelial pellet for CR was significantly influenced by physicochemical parameters. Thermodynamic result showed that the biosorption process was endothermic. The maximum adsorption capacity can be obtained from the Langmuir model, which is 316.46 mg/g, it suggests that mycelial pellet was an efficient biosorbent to remove CR from aqueous solution. This study indicates that the mycelial pellet can develop a sustainable approach to eliminate CR from the wastewater.

“…The study found that the main mechanisms of the adsorption process are surface complexation, cation exchange, and precipitation. 54 It can be seen that the mold mycelial pellets have a good bioadsorption performance of heavy metals, also has a biological reductive in some cases, which play a role in reducing toxicity. 55 As an environmentally friendly material with high tolerance and recycling, mycelial pellets can play a good role in continuous treatment of heavy-metal wastewater.…”

The mycelial pellet is a microbial aggregator formed under certain conditions. Besides the ability to secrete metabolites and adsorb a large amount of pollutants, the mycelial pellet has the characteristics of high biological activity, fast sedimentation speed, and easy solid−liquid separation. The technology of the mycelial pellet has been considered to be a promising technology for biomass utilization. To date, the mycelial pellet has been extensively studied for the production of various valuable products. Applications of mycelial pellets for microalgal biomass harvesting and wastewater treatment have also received more attention in recent years. Nevertheless, there are still some difficulties in the practical application of mycelial pellet technology. This review focuses on the characteristics, formation mechanism, formation conditions, and application research of mycelial pellets. This study provides much knowledge and information on the application technology of mycelial pellets in water pollution control, microalgae biomass harvesting, and industrial fermentation production. Problems existing in the scientific research and the main development trends of mycelial pellets are presented.

“…Because of their size, such beads can be easily separated from treated water in a batch reactor or used in a fixed-bed operation (Wang et al 2018a , b ). In a recent study, Bai et al ( 2020 ) prepared spheres of PBNPs by mixing them with mycelial (vegetative part of fungus) pellets. Cadmium uptake reached as high as 102 mg g −1 , for which surface complexation, cation exchange, and cadmium hydroxide precipitation were identified as the driving mechanisms.…”

Nanoparticles are abundant in the subsurface, soil, streams, and water bodies, and are often a critical control on elemental speciation, transport and cycling in the natural environment. This review provides an overview of pyrolyzed biomass-derived nanoparticles (PBNPs), their surface properties and reactivity towards aqueous species. We focus specifically on biochar-derived nanoparticles and activated carbon-derived nanoparticles which fall under our classification of PBNPs. Activated carbon-iron (nano)composites are included in some instances where there are significant gaps in literature because of their environmental relevance. Increased use of activated carbon, along with a resurgence in the manufacture and application of biochar for water treatment and soil amendment, has generated significant concerns about the mobility and toxicity of PBNPs derived from the bulk material in environmental applications. Recent examples are discussed to highlight current progress in understanding the influence of PBNPs on contaminant transport, followed by a critical discussion of gaps and future research directions.
