In this work, fungal hyphae (FH, Irpex lacteus) was used as the carbon resource for the preparation of porous carbon materials (PCFH) using mixed alkali as the activator. The SEM, N2 adsorption/desorption, FT-IR, XRD, Raman, and XPS were used to characterize the structure and surface properties of PCFH. The results showed that the PCFH not only has a huge Brunauer–Emmett–Teller (BET) surface area (2480 m2 g−1), but also has abundant functional groups containing carbon, oxygen, and nitrogen. Rhodamine B (RhB) was selected to evaluate the adsorption properties of the PCFH prepared under different conditions in dyeing wastewater. A fast adsorption rate was observed, and an uptake capacity of 765 mg g−1 was achieved in the initial 5 min. The maximum adsorption capacity of PCFH to RhB reached 1912 mg g−1 at the pH value of 9, which could efficiently remove RhB from the aqueous solution. The adsorption process was fitted better by a pseudo-second order model, and the adsorption isotherm for the RhB was well fitted by the Freundlich model. Moreover, the probable mechanism of adsorption was analyzed. In short, the good adsorption performance of PCFH indicated that it has a broad application prospect for dye water pollution control.

Iron, one of the most abundant elements on earth and an essential element for living organisms, plays a crucial role in our daily metabolism. In the field of catalysis, the development of high-performance catalysts based on less toxic iron element is also of significant importance for green chemistry and a sustainable future. To construct Fe-based heterogeneous catalysts with excellent hydrogenation performance, precise modulation of the atomic coordination structure is a key strategy for enhancing catalytic activity. In this study, we present an in-situ coating method for applying a zeolitic imidazolate framework (ZIF) onto the surface of fungal hyphae. The asymmetric coordination structure of Fe 1 -N 3 P 1 was precisely tailored by utilizing the phosphorus source from the fungus and the nitrogen source in the ZIFs. Detailed characterizations and density functional theory calculations revealed that the incorporation of ZIFs not only increased the specific surface area of catalysts, but also facilitated the dispersion of Fe 2 P nanoparticles into the Fe 1 -N 3 P 1 center, making the lowest reaction energy barrier and resulting in the best performance for nitrobenzene hydrogenation when compared to the Fe 2 P nanoparticles and clusters. This research introduces a novel design concept for constructing asymmetric monoatomic configuration based on the inherent characteristics of natural microorganisms and the exogenous porous coordination polymers.

Etoxazole is a widely used insecticide that poses a serious threat to both ecosystems and human health. In present study, a novel strain Paracoccus versutus Y4 was isolated and identified. More than 98 % of the etoxazole (10 mg/L) was degraded as the sole carbon source within 8 d by strain Y4 in liquid culture. HPLC MS/MS analysis revealed three possible intermediates, and a novel metabolic pathway of etoxazole including oxidation, dehydrogenation, and hydrolysis reactions was proposed. The Toxicity Estimation Software Tool suggests that the biodegradation intermediates were less harmful than etoxazole. Whole-genome sequencing revealed that the genome size of P. versutus Y4 was 5320,902 bp containing 5187 coding sequences. Among them, the gene coding monooxygenase, dehydrogenase and hydrolase may be responsible for etoxazole biodegradation. The results of molecular docking analysis suggested that the monooxygenase, dehydrogenase, and hydrolase from strain Y4 may facilitate catalytic degradation through efficient substrate binding. Compared with diatomite carrier, fungal mycelium carrier can promote the growth of strain Y4. In the soil degradation experiments, the fungal mycelium carrier promoted etoxazole degradation by strain Y4 in both fresh and sterilized soil. Treatment with Y4 +fungal mycelium significantly reduced the half-life of etoxazole in fresh soil from 24.2 to 6.3 d. Our study is the first to isolate etoxazole-degrading bacteria and provides a new strategy for the bioremediation of pesticide pollution by combining degrading microbes and fungal mycelium carriers.

Selective adsorption is of high value in many important areas, but this is a well-known challenge. Here, a self-supporting carbon film electrode, used as anode for selective adsorption of NO 3 – , was fabricated successfully by using fungus hyphae as feedstock. The removal of NO 3 – by the carbon film electrode is 0.345 m mol/g anode , accounting for 85.2 % of the total removed anions. The selectivity of NO 3 – over Cl - and NO 3 – over SO 4 2- is 6.7 and 13.8, respectively. The preferential electrosorption is relevant to the narrow micropores structure and the nitrogen doping of the carbon film, based on the pore size analysis and density functional calculation. This work opens a hopeful window in providing an effective approach to fabricate electrosorption materials and also could inspire the future development of selective materials for electrosorption of target ions.

Plastic-induced pollution has recently triggered global environmental, biodiversity, and public health concerns. Plastic micro/nanoparticles suspended in water that are non-recyclable and non-degradable are found in plants, animals, and even human blood, and their remediation represents an emergent societal need. In this study, a highly efficient strategy is reported to remove microplastics by using a sustainable framework derived from fungal mycelium (FM), which has reached a record capacity at 2.49 g g −1 , as it is known. This excellent removal capacity results from both the inherent properties and surface cationization of the FM. First, FM has a loose entanglement and porous structure with extracellular polymeric substances on the surface, which endows FM with the capacity to adsorb microplastics. Second, FM is engineered with 2,3-epoxypropyltrimethylammonium chloride (EPTAC) to enable its positively charged surface, which significantly enhances the adsorption of microplastics. Kinetic analysis and density functional theory reveal that the excellent microplastic removal is attributed to the enhanced electrostatic interaction between microplastics and EPTAC- g -FM. Along with the inherent merits of FM, which are natural, renewable, biodegradable, environmentally friendly, and easy to scale up, FM represents a green, facile, and cost-effective next-generation technology for remediating microplastics in clean water.

In this study, fungal mycelium ( Aspergillus niger and Myrothecium verrucaria ) were used to prepare modified hierarchical porous carbons through a simple way, that is, the fungal mycelium were added to the medium and the composite materials were formed by combining the growth characteristics of the microorganism with agar. After carbonization and activation process, the obtained Aspergillus niger -agar hierarchical porous carbon (HCAAN, 4343.3 m 2 g −1 ) and Myrothecium verrucaria -agar hierarchical porous carbon (HCAMV, 3520.1 m 2 g −1 ) have ultra-high specific surface area. While the synthetic dye brilliant green (BG) and antibiotic tetracycline hydrochloride (THC) were used as organic pollutants models, the maximum adsorption capacities of HCAAN and HCAMV for BG were 3364.34 and 3144.56 mg g −1 , and for THC were 1441.29 and 1279.21 mg g −1 , respectively. This study proved that the modification of fungal mycelium could indeed improve the performances of the composite materials, and more importantly, it provided a new strategy for the exploration of other microbial composites.

Capacitive deionization (CDI) is an emerging technology for water desalination, especially low-salinity water. Freestanding porous carbon-based electrodes with rapid electron transfer rate and effective ion diffusion features are desired to achieve high desalination performance. Here, a porous carbon pad derived from the fungal hyphae of Aspergillus niger was prepared as a precursor of the electrode. After carbonization and activation, the intertwined and hierarchical porous structure of the fungal hypha pad was well-preserved, producing a freestanding fungal hypha activated carbon pad (FhACPad) electrode for MCDI. The interconnected carbon fibers and open pore structure of the FhACPad yielded an electrode with high electrical conductivity and rapid ion transport properties. The novel FhACPad exhibited a gravimetric salt adsorption capacity of 35.6 ± 2.3 mg NaCl /g with an average desalination rate of 1.2 mg NaCl /g electrode /min from a 585 mg/L NaCl aqueous solution at a cell voltage of 1.2 V and a flow rate of 1 mL/min. As a result, the FhACPad outperformed conventional powdered activated carbon (PAC) electrodes and the most recently reported porous carbon electrodes under similar desalination conditions. This work also provides insights into the structure-performance relationships of CDI electrodes and shows a great potential of fungal biomass-derived porous carbon electrodes for high-performance MCDI applications.

Straw, a predominant agricultural residue, represents a significant waste product. Harnessing its potential is of paramount importance both in terms of research and economic value. In this study, chemically pretreated corn straw was infused with distinct microbial fungal mycelium variants and subsequently transformed into a series of biochars through a process involving carbonization and activation. The findings revealed enhancements in the specific surface area and total pore volume of mycelium-doped straw biochars compared to the original corn straw biochar (BCS). Additionally, discernible disparities were observed in their physical and chemical attributes, encompassing functional groups, surface chemistry, and micro-morphology. Notably, in water-based antibiotic removal experiments focusing on tetracycline hydrochloride (TH) and chloramphenicol (CP), the mycelium-doped straw biochars outperformed BCS. Their maximum adsorption capacities for TH and CP surpassed those of alternative adsorbents, including other biochars. Impressively, even after five cycles, the biochar exhibited a removal rate exceeding 80%, attesting to its robust stability. This study successfully emphasized the efficacy of incorporating fungal mycelium to enhance the adsorption properties of straw-based biochar, introducing a new theoretical basis for the development of lignocellulosic materials.

Nanozymes have gained significant attention in the degradation of environmental pollutants due to their low cost and reusability. Peroxidase nanozymes, widely studied for pollutant degradation, are limited in the food industry due to hydrogen peroxide's potential damage to nutritional components. To address this, we designed a metal-organic framework material, Zirconium-Metalloporphyrin (PCN-222(Mn)), which integrates adsorption, enzyme catalysis, and photocatalysis activities. This system offers high specific surface areas for contaminant accumulation, superior laccase-like activities that eliminate the need for H 2 O 2 , and enhanced visible-light absorption due to metalloporphyrin incorporation, effectively addressing multiple challenges in mycotoxin degradation. It achieved a groundbreaking degradation efficiency of 18 mg/g within just 60 min. Furthermore, due to the challenge of recovering MOF powders, we incorporated PCN-222(Mn) into fungal mycelium to create a safe, biodegradable composite film for ochratoxin degradation in edible oil. This approach not only enhances the stability and recyclability of the MOF material but also makes it more suitable for use in food systems.

High-performance electrode materials are critical for the development of the capacitive deionization (CDI) technology for efficient water desalination. In this study, binder-free porous carbon electrodes were successfully prepared from the fungal hyphae sheet with the formation and growth of metal-organic framework (MOF) crystals on the surface of hyphal fibers. The continuous fungal fibrous structure with abundant surface functional groups provided an ideal supporting substrate for in-situ oriented MOF growth. The MOF-fungal hyphae derived carbon (MOF-Fhy-C) exhibited an excellent property for CDI application, such as a large accessible surface area, excellent electrical conductivity, high porosity and hydrophilicity. The MOF-Fhy-C electrode achieved an outstanding CDI performance with a salt adsorption capacity of 40.8 mg/g and an average salt adsorption rate of 1.4 mg/(g·min) for treating 10 mmol/L NaCl solution at a cell voltage of 1.2 V, which are considerably higher than most of carbon-based electrodes reported in the literature. This research presents an effective strategy for fabricating freestanding CDI electrodes from fungal materials with MOF for high-performance desalination.

Nowadays, extensive use of copper in electric industries has severely contaminated aquatic environments. To address this issue, combining fungal biomass with nanomaterials is considered as an efficient way for adsorbing heavy metals from wastewater. In this work, a novel composite material
"Fungal mycelium coupled with Carbon nanotubes" (FM-CNTs) was synthesized and used for adsorption of Cu(II) ions in aqueous solution. To begin with, potassium permanganate and concentrated nitric acid were used as strong oxidants to modify the surface of CNTs, creating additional carboxyl
groups for coupling with amine groups from the surface of FM. Next, various characterization approaches such as SEM-EDX, FT-IR, XPS and TGA, were used to investigate the interaction between FM-CNTs and Cu(II) ions. Characterization results showed that the surface of FM-CNTs were significantly
changed after absorbing Cu(II) ions. Further, the effect of pH on adsorption capacity of FM-CNTs for Cu(II) was explored, showing that FM-CNTs had the best adsorption performance at pH of 5. Finally, Langmuir-Freundlich isothermal models were performed to analyze the adsorption behavior of
FM-CNTs for Cu(II). The experimental data from the adsorption of Cu(II) by FM-CNTs were best fitted to the Langmuir model, and the maximum adsorption amount of the FMCNTs for Cu(II) was found to be 342.22 mg/g. More importantly, FM-CNTs showed better adsorption capacity than fungal mycelium
alone. Overall, FM-CNTs exhibited excellent performance for adsorption of Cu(II) ions, thus greatly broadening its application prospects in copper-contaminated wastewater treatment.

Fungal mycelial pellets (MPs) exhibit high biomass-loading capacity; however, their application in wastewater treatment is constrained by structural fragility and the risk of environmental dispersion. To overcome these limitations, a dual-crosslinked polyvinyl alcohol–alginate gel (10% PVA, 2% sodium alginate) embedding strategy was developed and stabilized using 2% CaCl2and saturated boric acid. This encapsulation enhanced the tensile strength of MPs by 499% (310.4 vs. 62.1 kPa) and improved their settling velocity by 2.3-fold (1.12 vs. 0.49 cm/s), which was critical for stability under turbulent bioreactor conditions. Following encapsulation, the specific oxygen uptake rates (SOURs) of three fungal strains (F557, Y3, and F507) decreased by 30.3%, 54.8%, and 48.3%, respectively, while maintaining metabolic functionality. SEM revealed tight adhesion between the gel layer and both surface and internal hyphae, with the preservation of porous channels conducive to microbial colonization. In sequential-batch reactors treating sulfamethoxazole (SMX)-contaminated wastewater, gel-encapsulated MPs combined with acclimated sludge consistently achieved 72–75% SMX removal efficiency over six cycles, outperforming uncoated MPs (efficiency decreased from 81.2% to 58.7%) and pure gel–sludge composites (34–39%). The gel coating inhibited hyphal dispersion by over 90% and resisted mechanical disintegration under 24 h agitation. This approach offers a scalable and environmentally sustainable means of enhancing MPs’ operational stability in continuous-flow systems while mitigating fungal dissemination risks.
