“…The fungal biomass containing pollutant can be used for the development of constructing material such as brick, tiles, roofing material, etc. (Ipeaiyeda et al, 2020; Moser et al, 2017). Utilization of fungal biomass, firstly for nanoparticles, synthetizes and, secondly for employing the retentate biomass (B R ) for the removal of reactive dye from synthetic wastewater, clearly indicates the dual application of biomass in a novel way.…”

The present study utilized Aspergillus spp. for the synthesis of silver nanoparticles (AgNPs); the developed AgNPs were categorized using analytical techniques, that is, ultraviolet–visible (UV–vis) spectrophotometer, Zeta‐potential, dynamic light scattering (DLS), and transmission electron microscopy (TEM). A sharp peak of 463 nm highlighted the synthesis of AgNPs; further Zeta‐potential of −16 mV indicates stability of synthesized AgNPs. The TEM micrograph showed spherical and hexagonal shapes of synthesized AgNPs of 6–25 nm. The photocatalytic activity of fungal‐mediated AgNPs was evaluated for degradation of reactive yellow dye in the concentration range of 20–100 mg L−1. The results showed efficient degradation of dye using AgNPs in short span of time. For antibacterial activity, synthesized AgNPs, antibiotic, and AgNPs + antibiotic were tested. As per results, the zone of inhibition (ZOI) of AgNPs showed the values of 13 and 10 mm for Escherichia coli and Staphylococcus aureus, respectively. Further, the ZOI of penicillin highlighted the values of 18 and 17 mm for E. coli and S. aureus, respectively. When AgNPs and penicillin were used in combination, a clear synergistic effect was observed; the ZOI showed 0.49‐ and 0.36‐fold increase in area against E. coli and S. aureus, respectively, in comparison with penicillin or AgNPs alone. Further, the leftover biomass (retentate biomass) was used to decolorize the reactive yellow dye at different initial concentration ranging from 20 to 100 mg L−1. It was observed that 1 g L−1 retentate biomass (BR) can effectively remove 82%–100% dye at 20 and 100 mg L−1 initial dye concentration. Results also indicated that with increase in initial reactive dye concentration from 20 to 100 mg L−1, the decolorization capacity of retentate biomass (BR) (at 0.2 g L−1) decreased from 79.2% to 32.3%. However, the use of AgNPs synthesized leftover fungal biomass can be a good option for up taking the additional dyes/contaminants, and also as leftover biomass can be utilized effectively, it can prove to be an excellent approach for environment safety. As the literature studies did not mentioned the further use of retentate biomass, the present study provides an excellent approach for further research on this aspect. Practitioner points Synthesis of AgNPs from Aspergillus spp. and characterized with the help of a U.V‐vis spectrophotometer, a zeta potential, DLS and TEM. The developed AgNPs were used for antibacterial and dye degradation activity. The left over (retentate) fungal biomass was used further for additional dye degradation activity

“…This versatility ultimately results in mycelium materials with various properties and with a potential for different applications . It is worth noting that most of the mycelium-based biocomposites are in the proof-of-concept stage because of the need for optimization of the many parameters involved in the production process. , From the proof-of-concept stage, a wide array of applications have been targeted; particularly, the building and construction could largely benefit from the development of the mycelium biocomposites. ,,, The other emerging applications include sustainable fashion (mycelium leather), ,, packaging (foams), , chitin paper, automotive parts, and flexible electronics. , …”

“…Similarly, the compressive strength of the resultant mycelium products was reported to increase 3-fold by blending natural fibers with inorganic additives such as silica, clay, as well as natural sand or aggregates. 61 It is worthwhile noting that agroindustrial residues form the most significant resource as a substrate for mycelium growth and production of biocomposite due to their availability, low-cost and ecofriendly attributes. These agro-industrial residues include but are not limited to sugar cane bagasse, rice husks, cotton stalks, wheat straw, and corn stover.…”

Extrication from the use of fossil-based products has grown more critical in recent years. This disengagement has been driven by deliberate environmental campaigns focusing on climate change and global warming threats and their consequences to humanity. As such, innovative replacements for fossilbased products, primarily by biobased materials, have recently been of considerable interest. Among the biobased materials, mycelium-bound biocomposites enhanced biologically or by nontoxic additives are one of the most creative and ecofriendly solutions because it fulfills the three pillars of sustainable development with positive impacts via circular economy design principles. In this review, the potential of mycelium-bound biocomposites is elucidated by comprehensively covering their state-of-the-art production from design strategies (variety of species, substrates, additives, and growth conditions) to postprocessing techniques and the resulting advanced material features. This review also covers the intriguing and growing areas of applications for mycelium-bound biocomposites, as well as the future outlook for enhanced material circularity and sustainability.

Engineered Living Materials (ELMs) are materials composed of or incorporating living cells as essential functional units. These materials can be created using bottom-up approaches, where engineered cells spontaneously form welldefined aggregates. Alternatively, top-down methods employ advanced materials science techniques to integrate cells with various kinds of materials, creating hybrids where cells and materials are intricately combined. ELMs blend synthetic biology with materials science, allowing for dynamic responses to environmental stimuli such as stress, pH, humidity, temperature, and light. These materials exhibit unique "living" properties, including self-healing, self-replication, and environmental adaptability, making them highly suitable for a wide range of applications in medicine, environmental conservation, and manufacturing. Their inherent biocompatibility and ability to undergo genetic modifications allow for customized functionalities and prolonged sustainability. This review highlights the transformative impact of ELMs over recent decades, particularly in healthcare and environmental protection. We discuss current preparation methods, including the use of endogenous and exogenous scaffolds, living assembly, 3D bioprinting, and electrospinning. Emphasis is placed on ongoing research and technological advancements necessary to enhance the safety, functionality, and practical applicability of ELMs in real-world contexts.
