摘要

Purpose

Agro-industrial residues such as sugarcane vinasse pose significant environmental challenges due to their high organic load and limited reuse pathways. This study evaluates a biological waste-valorization approach using native fungal strains for producing mycelium-based material precursors.

Methods

Four indigenous fungal species were screened across multiple culture media. Abortiporus biennis was selected for further evaluation on vinasse-based substrates under solid-state and submerged cultivation conditions, with and without wheat bran supplementation. Optical microscopy, scanning electron microscopy (SEM), and the phenol–sulfuric acid method were used for characterization.

Results

Abortiporus biennis exhibited the most consistent and rapid growth among the tested strains, achieving full colonization of 60 mm Petri dishes within 2–3 days on CGA and SDA media. In vinasse-only conditions, the G-factor decreased from 63.9 μm at 24 h to 53.9 μm at 72 h, whereas wheat bran supplementation was associated with increased growth performance, as reflected by an increase in the G-factor from 84 μm to 146 μm over the same period. Sugar concentration in wheat bran-containing cultures increased over time, suggesting active substrate utilization and release of soluble sugars.

Conclusion

Sugarcane vinasse and wheat bran may serve as suitable feedstocks for early-stage biological mycelium–substrate precursor formation. The increase in G-factor with wheat bran supplementation suggests changes in hyphal growth characteristics under nutrient-enriched conditions. These findings provide preliminary evidence for the potential use of locally available agro-industrial residues in sustainable material development, although further mechanical and physicochemical characterization is needed to validate material performance.
