“…From an industrial point of view, it has been observed that the benefits of the fungus-derived material over the other leather substitutes include the simplicity of biomass cultivation (fungi can be grown under controlled fermentation conditions), the fungi's shorter growth period, and the lower carbon footprint [ 47 ]. In this research work, most strains that we discussed here are well-known for enzyme production and were less known for their application in bio-based materials.…”

“…In more recent studies, the flexible nature of the pure mycelial mats has come to the forefront as a potential substitute for non-woven materials such as animalderived leather and petroleum-based faux leather alternatives (Crawford 2023c;Crawford et al 2023). This has prompted a rise in research that investigates the development of these bio textiles and their associated properties, which this paper builds upon (Amobonye et al 2023;Raman et al 2022;Rathinamoorthy et al 2023b;Williams et al 2022).…”

This research investigates a novel method for cultivating mycelium-based leather substitutes using a carefully formulated paste consistency substrate. The primary objectives are to enhance nutrient availability, facilitate scalability, and streamline cultivation processes. The study spans a 21-day cultivation period, during which a flower-based medium is employed, eliminating the need for labor-intensive harvesting techniques. Two fungal species, Ganoderma lucidum (rishi) and Pleurotus djamor (pink oyster) are tested to assess their compatibility with the growth method. These species were chosen based on their rapid colonization rates and inherent resilience. The investigation delves into various combinations of crosslinking agents, including glycerol (a plasticizer), commercial tanner, citric acid, and magnesium sulfate. The effects of these agents on tensile strength are compared and qualitative data is analyzed through the use of scanning electron microscopy (SEM) and stereo microscopy. Furthermore, the study explores the fabrication potential of non-woven textiles derived from mycelium, emphasizing their suitability as eco-friendly leather alternatives. Scaled prototypes are highlighted to demonstrate their feasibility. Post-treatment processes, such as dyeing with bio-based dyes and acrylic leather paint, are evaluated for their aesthetic impact. The research contributes a biodegradable material alternative that addresses the environmental challenges of high textile consumption. The findings add to the growing body of sustainable design methods in the realm of leather-like materials in bio-design.

“…Nevertheless, other structures are present on the mycelium cell wall, such as proteins (e.g., mannoproteins, hydrophobins) and glucans [7]. Mycelium-based material stands out as a sustainable alternative to animal or synthetic leather, which present a higher environmental impact [8]. On the one hand, natural leather generates a large amount of toxic waste emissions, particularly from the tanning process, in which heavy metals, acids and dyes are employed [9].…”

Plasma technology is increasing its applications in the textile industry for conferring surface functionalities through greener processes. In this study, plasma treatments are studied to improve the wettability of mycelium-based material, an emerging material with a lot of potential in the near future. The plasma effect was characterized by assessing the added functionality (wettability) and inspecting surface modifications with different techniques, such as scanning electron microscopy (SEM) and X-Ray photoelectron spectroscopy (XPS). Low pressure plasma (LPP) treatments were successfully applied into the mycelium-based material and optimal power of discharge and treatment time were set for this material (750 W, 17.5 min). With the optimized LPP treatments, the water absorption capacity of mycelium-based material was improved by 2000% and some surface morphological modifications were observed by SEM analysis. On the other hand, XPS analysis demonstrated how the plasma treatment changes the surface composition.
